SNC 5100
Transfer Rates: Ultra, Fast, and Asynchronous
The SCSI protocol defines two methods of data transfer: synchronous and
asynchronous. Asynchronous transfers may run as fast as 5 MB/sec, while
synchronous transfers may run as fast as 180 MB/sec (Ultra2/3) at block sizes
of 256 k. Performance is system and configuration dependent.
The rate of transfer is negotiated between a SCSI initiator, such as the SNC
5100, and each target. For each target device identified during a bus scan, the
SNC 5100 will request a transfer rate at the fastest transfer rate supported by
the SNC 5100. The target will then reply with the maximum transfer rate it will
support.
Caution
In general, devices that are capable of running at Ultra2/3 speeds should not be
mixed on a bus with slower devices, since the bus speed will be set to match the
slowest device on the bus.
Wide and Narrow SCSI Buses
A SCSI bus may be either narrow (8 bit) or wide (16 bit). The SNC 5100 SCSI
buses are all wide, but may be connected to narrow devices with the correct
cable adapters.
Although it is possible to mix narrow and wide devices on a single SCSI bus,
this configuration is not recommended. If any of the devices supports Ultra2/3
speeds, then a mix of narrow and wide devices is prohibited.
In order for the SNC 5100 to locate and communicate with the devices, each
device on the SCSI bus must be assigned a unique target ID. On a wide (16 bit)
SCSI bus, the SCSI standard allows for a total of 16 target IDs. On a narrow (8
bit) SCSI bus, the SCSI standard allows for a total of 8 target IDs. There are no
requirements about the ordering or position of the target IDs on the SCSI bus.
The only requirement is that there be no duplicate target IDs. By default, the
SNC 5100 uses ID 7. Thus, peripheral devices may be assigned IDs 0 through 6
and 8 through 15, typically selected by a switch or jumpers. These settings may
be changed.
Caution
Make sure you do not assign more than one device on a bus to the same target
ID. This will prevent that bus from working properly.

SNC5100
The SCSI protocol also defines a priority-based arbitration method, based on
the target ID of the device attaching to the bus. The SCSI ID priority order is,
from highest to lowest, 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8.
Table of SCSI Terminology and Limitations
The following table (look for updates at http://www.scsita.org/) defines the
number of devices supported, based on the negotiated transfer type. When
reviewing the limitations of a bus, the capabilities of the fastest devices must be
considered. The bus length indicates total SCSI bus length, including any
internal device cables, rather than the length between any two devices.

SCSI Bus Termination
Each end of a SCSI bus must be terminated correctly. The SNC 5100 provides
termination on each of its buses. The terminators can be disabled using a
jumper on the SNC 5100 motherboard.
The terminators can also be enabled or disabled from the ADIC Management
Console. For more information on SCSI Channel configuration, see the ADIC
Management Console User Guide.
Caution
Improper SCSI bus termination may result in excessive errors on the SCSI bus,
and may lead to data corruption or the inability to communicate with target
devices.
The SNC 5100 provides termination power on all SCSI buses for external
terminators.
Many SCSI target devices have internal terminators. It is imperative that the
terminators be disabled for all devices EXCEPT those at the physical ends of
the SCSI bus.
Problems on the SCSI Bus
When a SCSI bus fails to operate correctly, it is most often caused by incorrect
connections to the SCSI bus. Common problems include:

SNC5100
Missing terminator at the end of a SCSI bus
Check that an external terminator is attached or that the end device has
termination enabled.
Excessive termination
Check that all devices other than the end devices have termination disabled.
Multiple devices at the same ID
If two or more devices are configured at the same SCSI ID, only one of those
devices will be seen by the SNC 5100, and data transfers to that device will be
unreliable. Check that only one device is set to each ID.
Target device set to initiator’s ID
If a target device is set to the same ID as the SNC 5100 (ID 7), the bus will be
unstable and targets will not be identified. Check that no target devices are set
to ID 7, or if one must be set to 7, change the SNC 5100 Initiator ID.
Bent pins in a SCSI connector
The pins in the SCSI connectors are somewhat fragile. Inspect each connector
to find pins that were bent when the connector was attached. Replace any
cables with bent pins.
Improper device type
A DE device on an SE bus or an SE device on a DE bus will cause the bus to be
unusable.
Improper terminator type
A DE terminator on an SE bus or an SE terminator on a DE bus will cause the
bus to be unusable.

SNC 5100
Inadequate cables
Older cables may not be suitable for running at Ultra speeds. Be sure all cables
are rated for Ultra.
Mixed cable types
If a SCSI bus has both round cables and flat ribbon cables, it may suffer
problems when running at Ultra speeds. Use the same cable type consistently
for all segments of the SCSI bus.
Unshielded cables
An unshielded SCSI cable used external to a cabinet may cause reliability
problems, due to interference from other electrical devices. Use only shielded
cables.
Fuses
The SNC 5100 has a 3.15A, 250 VAC, time delay fuse on the AC line input,
and the AC harness uses an axial lead, 250 VAC time delay fuse in the neutral
line. There are no user-serviceable parts in the SNC 5100.
Host Bus Adapter Setup
Hosts are connected to the SNC 5100 through specific Host Bus Adapters
(HBAs). The installation procedure varies slightly, depending on which adapter
you will be using. The procedure involves these steps:
Step 1.
Install the adapter in the host system, following the manufacturer’s
recommendations.
Step 2.
Power on the host system and update the adapter firmware, if
necessary.
Step 3.
Step 4.

Installing the SAN Explorer
The SAN Explorer software is only available for hosts running the Windows
NT or Windows 2000 operating systems. It allows you to view the LUN
mapping through switches to which your SNC 5100 may be attached.
It includes the Host Registration Service. The Host Registration Service
provides the SNC 5100 with periodic host status information including the host
name, host type and HBA. The default notification period is 15 minutes.
See the readme file on the CD-ROM for installation instructions. For software
updates, visit www.adic.com.
Installing the Host Registration Service
The Host Registration Service is available without the SAN Explorer software
for host operating systems other than Windows NT or Windows 2000. It
provides the SNC 5100 with periodic host status information including the host
name, host type and HBA. The default notification period is 15 minutes.
See the readme file on the CD-ROM for installation instructions. For software
updates, visit www.adic.com.
Power-Up and Boot Sequence Guidelines
The SNC 5100 scans the SCSI buses after it boots. If you add or remove SCSI
devices after the SNC 5100 has booted, it will not detect the changes until you
invoke a SCSI rescan or reboot.
Before you turn on or restart the hosts that are connected to the SNC 5100, you
must wait until the SNC 5100 has finished booting. You will know that the
SNC 5100 has finished booting when the RDY LED on the user panel blinks at
intervals of one second.

Check SCSI Bus Termination
Caution
If in this procedure you determine that you need to remove a SCSI
cable or terminator, all I/O to the SNC 5100 must be stopped and
the SNC 5100 must be turned off.
Step 1.
Verify the termination for the end device attached to the channel in
question.
The last physical device on a chain of SCSI devices needs to be
terminated.
If the end device has internal termination, be sure it is enabled.
Otherwise check that an external terminator is attached to the
device.
A Differential (DE) terminator on a Single Ended (SE) bus or an SE
terminator on a DE bus will cause the bus to be unusable.
Step 2.
Verify the termination for the other devices attached to the channel
in question.
Check that all SCSI devices other than the end devices have internal
termination disabled.
A Differential (DE) terminator on a Single Ended (SE) bus or an SE
terminator on a DE bus will cause the bus to be unusable.
Step 3.
Step 4.
If there are SCSI termination problems, power down the SNC 5100
down and correct them.
If you corrected SCSI termination problems, go to "SCSI Health
If you powered down the SNC 5100 down, turn it back on.

Check for Multiple SCSI IDs
If two or more devices on the same SCSI channel are configured at the same
SCSI ID, only one of those devices will be seen by the SNC 5100. Data
transfers to that device will be unreliable.
Caution
If in this procedure you determine that you need to correct any
SCSI IDs, all I/O to the SNC 5100 must be stopped and the SNC
5100 must be turned off.
Step 1.
Enter the scsiShowcommand from the service terminal.
Step 2.
Step 3.
Write down the SCSI IDs of all devices connected to each SCSI
channel.
Check that only one device is set to each ID for each SCSI channel.
Assign a new SCSI ID to any conflicting target device.
Step 4.
Check that for each SCSI Channel, no devices are set to ID 7 except
the SNC 5100 channel ID.
If a target device is set to the same ID as the SNC 5100 (ID 7), the
bus will be unstable and data corruption may result.

Improper Device Type
Step 1.
Check to be sure that all the devices attached to a single SCSI bus
are of the same type.
Only low voltage differential devices must be attached to low
voltage differential SCSI channels.
When a mix of Ultra2/3 SCSI and Ultra SCSI devices are connected
to a single bus, the bus will run at the Ultra SCSI speed. Because the
bus will auto-adjust to the slowest speed, it is not recommended that
you run both Ultra2/3 SCSI and Ultra SCSI devices on the same
bus.
Caution
If in this procedure you determine that you need to replace a SCSI
device, all I/O to the SNC 5100 must be stopped and it must be
turned off.
Step 2.

Examine SCSI Cables
Caution
If in this procedure you determine that you need to remove a SCSI
cable, all I/O to the SNC 5100 must be stopped and the SNC 5100
must be turned off.
Step 1.
Look for damaged cables.
Check for breaks in the cable jacket, exposed or frayed cable shield,
exposed or broken wires.
Step 2.
Step 3.
Replace any damaged cables.
Look for inadequate cables.
Older SCSI cables may not be suitable for running at Ultra2/3
speeds. Be sure all cables are rated for Ultra2/3.
Step 4.
Step 5.
Replace any cables not suitable for running at Ultra 2/3 speeds.
Check for mixed cable types.
If a SCSI bus has both round cables and flat ribbon cables, it may
suffer problems when running at Ultra2/3 speeds.
Use the same cable type consistently for all segments of the SCSI
bus.
Step 6.
Step 7.
Replace any cables that are of the wrong type.
Check for unshielded cables.
An unshielded SCSI cable used external to a cabinet may cause
reliability problems, due to interference from other electrical
devices.
Step 8.
Replace all unshielded cables.

SNC 5100
Removal and Replacement
Procedures
This section describes the removal and replacement procedures for the SNC
5100 in its entirety or for one or more of its GBICs.
Handling Electrostatic Discharge-Sensitive
Parts
Caution
It is highly recommended that you follow industry best practice when handling
Electrostatic Discharge (ESD) Sensitive Parts.
• Keep the ESD-sensitive part in a static-protective bag until you are ready
to install the part into the machine.
• Make the fewest possible movements with your body to prevent an
increase of static electricity from clothing, fibers, carpets, and furniture.
• If instructed to do so, switch off the machine power before you remove
ESD-sensitive parts.
• Just before touching the ESD-sensitive part, discharge to the machine any
static electricity in your body by touching the metal frame or cover of the
machine. If possible, keep one hand on the frame when you install or
remove an ESD-sensitive part.
• You may opt to wear an ESD wrist strap.
• Do not place any ESD-sensitive parts on the machine cover or on a metal
table because large metal objects can become discharge paths if they are
not grounded. If you must set aside an ESD-sensitive part, first place it
into the ESD static-protective bag.
• Prevent ESD-sensitive parts from being accidentally touched by other
personnel.
• If possible, keep all ESD-sensitive parts in a grounded metal case.
• Be very careful when you work with ESD-sensitive parts in cold weather.
Low humidity and heating increase static electricity.

If you need to set a netmask, specify it after the network address:
Example:
foster > ethAddrSet “10.0.0.2”, “255.0.0.0”
If you need a network route and/or default gateway, you must
specify it.
Example:
foster > gateAddrSet "192.168.1.1"
value = 0 = 0x0
When more complicated routing is required, use the route
command to specify the destination address, as a full address
(single host) or as an abbreviated subnet address.
Specify the address of the gateway that is reachable on the local
subnet.
Example:
foster > route "add", "206.0.0", "192.168.1.1"
value = 0 = 0x0
Step 4.
Optionally, add User account for Telnet
If you want to access the SNC 5100’s command line interface
through its Ethernet port using a Telnet session, you need to add a
user account.

Updating Firmware and Configurations
Although the ADIC Management Console is the simplest and most efficient
tool for updating firmware and saving/loading configurations, you can use the
service terminal as an alternate method to perform these operations.
For more information, see the ADIC Management Console User Guide.
The ADIC Management Console service port supports Zmodem file transfers.
The procedures below are specific for using the HyperTerminal program on the
service terminal to transfer files. Other terminal emulation programs operate in
a similar fashion.
The Zmodem send and receive functions in some terminal emulation programs
automatically issue the command string “rz” before sending a file and the
command string “sz” before receiving a file. However, even if the program you
are using automatically sends the “rz” command, manually issuing the
command string “rz” before starting the transfer has no negative effect on the
transfer.

Setting the Time and Date
Setting the Real Time Clock
Step 1.
Use the rtcDateSetcommand to manually set the Real Time
Clock.
For more information, see the
Example:
SN60023 > rtcDateSet 2001,1,26,5,9,30,00
value = 0 = 0x0
SN60023 >
Step 2.
Use the dateSetFromRTCcommand to set the SNC 5100’s RTC as
the source of date display.
Example:
SN60023 > dateSetFromRTC
value = 0 = 0x0
SN60023 >
Step 3.
Use the tzSetcommand to set the timezone. EST is used in the
example for Eastern Standard Time.

Step 4.
Use the datecommand to confirm.
Example:
SN60023 > date
SN60023 > FRI JAN 26 9:30:49 2001
SN60023 >
Caution
Use 24 hour time when programming the real time clock.
Caution
The time will be 1 hour off while Daylight Savings time is in effect.
Adding a Host System Running Timeserver
Step 1.
To enable the timeserver functionality use the setNettime
command.
Example:
SN60023 > setNettime 1
Nettime 1 value = 0 = 0x0
SN60023 >
Step 2.
Add a Host running timeserver to the SNC 5100 using the
setTimeHostcommand.

clearReservation[devId]
The clearReservationcommand can be used to force-clear a reservation
held by a host for the specified target device. It may be necessary to issue this
command if a host that has a reservation for a shared device was disconnected
from the SNC 5100 without properly shutting down the application software
that issued the reservation. If this is the case, other hosts that attempt to access
the shared device will repeatedly receive reservation conflict status from the
device. Issuing this command may result in resetting the target device.
Parameter

diagBoot
This command is used only to transition the SNC 5100 from normal operation
to the special diagnostic mode. The diagBootcommand first ensures that the
ffs:mt directory exists. It verifies that the files diagnstk.o and diagnstk.rc are in
the flash file system. If they are in the root directory, it moves them to the ffs:mt
directory.
It copies the existing bootline to a file in the ffs:mt directory on the SNC 5100
and installs a new bootline directing the SNC 5100 to boot using a special
diagnostic startup script ffs:mt/diagnstk.rc. It renames the persistent map file
config/device.map as config/device.bak (a new file will be generated after
rebooting).
Finally, diagBootissues a rebootcommand to put the changes into effect
Caution
After completing use of the diagnostic commands, use the
normalBootcommand to restore your system to normal operation.

command. Specify one of two option parameters as follows.
Option
Number
Value
1
2
Hides the Command and Control interface and results in Inquiry data
returning “device not available” for LUN 0.
Completely disables all Command and Control functions
The SNC 5100 is addressable as a SCSI target device for command and control
support. On a Fibre Channel Interface, this device will be seen as logical unit
number 0, (LUN 0). The LUN 0 device returns a device type of 0Ch in an
inquiry command, indicating it is a controller device. Controller devices are
defined in the SCSI-3 Controller Commands specification (SCC).
In some cases, it may be desirable to disable this feature. If LUN 0 is disabled,
then a device type of 2Ch will be returned in an inquiry to LUN 0, indicating
that the device is not presently available at this LUN. LUN 0 will remain
reserved for the Command and Control interface and will not be allocated to
another target device.
Other commands are available for re-enabling the Command and Control
interface or reassigning it to a different LUN rather than hiding or disabling it.
See the enableCC command and the setSnaCCLuncommand for further
information.
Caution
If you enter the disableCCcommand without specifying an option
number, it has the same effect as disableCC 1

fcPortModeSet [port],[mode]
The fcPortModeSetcommand sets the mode for the specified Fibre Channel
port. See also the fcPortModeGet command.
The default port mode is Public Target. Consequently, if attached to a Fabric
device the SNC 5100 will register as a Target with the name server. If the port
mode is Private Target, the SNC 5100 does not register with the name server
and the Fabric device will not recognize the SNC 5100 as a Target.
The port must be in Initiator mode if you want the SNC 5100 to scan for target
devices on the port. When the port is in Private Initiator mode, the SNC 5100
only scans for devices on the local loop. If the port mode is in Public Initiator
mode, the SNC 5100 also scans for devices attached to a Fabric.

mapCompressDatabase
Caution
Compressing the map database will cause device addresses to
change unpredictably. Use this command only when no host
systems are expecting devices to remain at their current addresses.
Occasionally, it may be necessary to eliminate inactive entries and reorder the
active entries in the Persistent Device Map database. The
mapCompressDatabasecommand removes entries for devices that are no
longer present and reassigns existing device entries to new addresses. The
devices will be assigned new addresses immediately and hosts must rescan for
devices or be rebooted.
This may be required when a host system has a limited number of logical units
that may be supported, and changing devices on the SNC 5100 has caused the
logical unit numbers to increase beyond the host’s supported level.
When you run this command you will be given the option of also clearing the
SFM access settings. Because devices will be assigned new addresses, clearing
the SFMdatabase ensures that hosts will not have access to the wrong LUNs.
Accepting this option requires that the system administrator must reassign
SFM access permissions between the hosts and LUNs.

This command will compress the Persistent Device Map.
Existing SFM Access Settings may become invalid and

operates against the device list output by the mapShowDatabasecommand.
Issue the mapShowDatabasecommand before and after issuing the
mapWinnowDatabaseLuncommand to verify functionality.
The mapWinnowDatabaseLUNcommand frees the LUN for use in the device
map. If the LUN is currently assigned to an attached device, no action is taken.
If the LUN refers only to historical data (device not currently attached), the
LUN is freed for reuse.

normalBoot
Certain commands and tests are only available in diagnosticmode.
Switching to diagnostic mode saves all configuration parameters so that they
are restored before returning to normal operation. Use the normalBoot
command to restore the SNC 5100 to normal operating conditions.
This command is used only to transition an SNC 5100 from the special
diagnostic mode to normal operations. It restores the bootline that was copied
by diagBoot. The new persistent device map is erased, and the original map
file is renamed config/device.maprestoring it for use when the SNC

The rebootcommand requests that the SNC 5100 shut down existing
operations and then restart. This is the preferred method of restarting the SNC
5100. There are processes running within the SNC 5100 that may have writes
pending to files within the flash file system. Following a reboot command,
these processes flush their data to the flash file system, and the flash file system
writes all pending data out to the flash memory. Only after all pending data has
successfully been written to flash, will the SNC 5100 start a reset cycle.

ridtag [“value”]
The ridtagcommand is used to change the replacement identifier (RID) tag
for the SNC 5100 after it has been replaced by the service representative. This
should be the final step after replacing and verifying that the replacement unit
is performing satisfactorily.
The sysVpdShowcommand will display the RID tag. Before replacing the
SNC 5100, you must determine the existing RID tag, if there is one, or the
original serial number if no replacement has been made.
If the ridtagcommand is entered with a string, that string becomes the RID
tag recorded for the unit.

route
The routeutilities maintain a route file, nvfs:/mgmt/route, which is
used at system startup to initialize the network routing table. Each route entry
is a single line of the format:
destination:gateway
where
destination is an IP address (for a subnet or host) or the name of a host that is
described in the hosts file.
gatewayis an IP address or the name of a gateway to a host. The gateway
must be a device on the local subnet.
An IP address is a text string in standard IP Address format (i.e., 10.0.0.2). A
host or gateway name must be listed in the hosts file.
Here is an example of the contents of the route file.
socrates:bruno
10.0.0:bruno
The first line instructs the system to reach the host “socrates” by directing the
IP packets to the host “bruno”. The second example shows how all traffic for
the subnet 10.0.0 (implied netmask is 255.255.255.0) is sent to the host
“bruno” for forwarding. By default, no routes are defined in the route file.
The routecommand is invoked to add, remove, and list the route table.
route “add”,“destination”,“gateway”
The route “add” command adds a route to the destination through the
gateway.

rtcDateSet[year],[month],[dayofmonth],[dayofweek],
[hour],[minute],[second]
The rtcDateSetcommand allows you to set the date and time manually.
• You must use a 24-hour clock.
• All parameters are digits.
• The year can be either two or four digits.
• Single digit months or hours should not be filled out with leading zeroes.
• A digit from 1-7 needs to be entered for the [dayofweek]parameter, but
it doesn’t matter what you enter, since the command will automatically
correct it if it is wrong.
To display the new time and date data after entering the rtcDateSet
command, enter the datecommand.
To set the RTC to 9:35 A.M. on Friday, January 26, 2001, enter the following

rz
The rzcommand initiates a receive Zmodem file transfer session. You use this
command when you want to download a file from the service terminal to the
SNC 5100. The file can be either a firmware or configuration file. After issuing
this command, you start the file transfer from the service terminal by initiating
a send file operation that uses Zmodem protocol.
The example below shows the rzcommand when it is used to receive a file that
contains operational firmware. The SNC 5100 extracts individual firmware
modules from the file and saves them temporarily in memory. After the file
transfer has completed, the SNC 5100 copies the firmware modules to
nonvolatile flash memory. The SNC 5100 must be rebooted to use the updated
firmware.

Rescanning a SCSI bus may delay I/O commands pending on that bus for
several seconds. Do not rescan SCSI buses when this delay may not be
tolerated. When possible, only scan the bus where a new device has been
added.
When a device is discovered, there may be further device specific initialization
that continues after the scan has completed in which case the device may not
show up immediately when you issue the fcShowDevscommand. Tape and
Changer devices that indicate Ready status are available on scan completion.
If a SCSI target device should require replacement, remove the old device, set
the new device to the same SCSI bus ID as the old device and attach it to the
same channel. Rescan the channel to update the configuration data. The new
device should be available to host systems with the same LUN as the old
device.

setSnaCCLun [newLUN]
The setSnaCCLuncommand reassigns the SNC 5100's Command and Control
LUN to the specified value.
newLUN is the new value for the Command and Control LUN. Valid values
are 0 through 127.
The new setting takes effect immediately. The previous value is removed from
the device map and database and a trap is generated indicating that the device
was removed.
If the new LUN is not currently in use, a new entry is added in the device map
and database. A trap will be generated indicating the new device was added.
If the new LUN is already in use, the Command and Control LUN will be
disabled. It will remain disabled until the device mapped at the requested LUN
is removed and deleted from the database. In this case, you can use the
mapRebuildDatabasecommand to remove the previous LUN assignment
and to allow the new Command and Control LUN to be enabled.
Caution
Because AIX and NT use LUN 0 when they issue a Report LUNs
command, you must make sure that a device is configured at LUN
0.

SNMP community strings serve to group network devices into logical
collections for management purposes. The community string must match on
both the ADIC Management Console Server and the SNC 5100 you wish to
manage. The default settings do match. Use the ADIC Management Console to
view or edit strings that apply to the Server.
For more information, see the ADIC Management Console User Guide.
To view or edit strings that apply to the SNC 5100, use the snmp... commands

SNC 5100
An example configuration that requires the Node Name on each Fibre Channel
port to be different is where the host has two Host Bus Adapters (HBAs)
installed for redundancy. In this configuration, each HBA is connected to a
different Fibre Channel port on the SNC 5100. Fail-over software on the host
defines one of the HBAs as the primary connection and the other HBA as a
spare. If the primary HBA should fail, the fail-over software routes data
transfers to the SNC 5100 through the spare HBA.

sz “filename”
The szcommand initiates a send Zmodem file transfer session. You use this
command when you want to save configuration information to a file in case the
SNC 5100 needs to be replaced. The SNC 5100 uses Zmodem protocol to
upload its persistent address map database and configuration parameter
settings from its nonvolatile flash memory to a file on the service terminal.
After issuing this command, you start the file transfer from the service terminal
by initiating a receive file operation that uses Zmodem protocol.
The filename “config.cfg” is shown in the example below. You can specify a
different name for the file but the name must not exceed 8 characters and it
must end in .cfg. See also the rzcommand for information about receiving a
configuration file.

SNC 5100
Diagnostic Command Reference
This section specifies the procedures used when diagnostics are required.
Boot Modes
The SNC 5100 has two modes of operation: normalmode and diagmode. Two
commands are available from the service terminal to reboot the SNC 5100 to
the desired mode. The SNC 5100 remains in the existing mode until it has been
directed to reboot in the other mode.
When the SNC 5100 is booted in diagmode, the command prompt displayed
on the service terminal is diagmode >. While in diagmode, a limited
command set is available for testing the SNC 5100 interfaces. In addition, the
device drivers for the Ethernet, Fibre Channel, and SCSI interfaces are disabled
so loop back tests can be performed on them.
Entering Diagnostic Mode
Use the diagBootcommand when the special features of the SNC 5100’s
diagnostic module are required.
Follow this procedure to enter diagnostic mode.
Step 1.
Stop all I/O.
Caution
Before entering diagmode, you must disconnect all SCSI and FC
cables from the SNC 5100. If you do not, the data on the attached
tape devices will become corrupted.
Step 2.
Step 3.
Step 4.
Step 5.
Step 6.
Shut down the SNC 5100.
Remove the Ethernet cable, if installed.
Connect the terminal to the Service Port.
Turn on the SNC 5100 and wait for it to finish booting.
If the command prompt displayed on the service terminal is
diagmode> , proceed with the appropriate diagnostic tests.

If the command prompt displayed on the service terminal is not
diagmode >, enter the diagBootcommand.
Step 7.
Step 8.
Wait for the SNC 5100 to reboot.
At the diagmode >prompt, proceed with the appropriate
diagnostic tests.
Restoring Normal Mode
Follow this procedure if the SNC 5100 was placed in diagnostic mode and
needs to be restored to normal operation.
Step 1.
Connect the terminal to the Service Port, if it is not already
connected.
Step 2.
If it is not already on, turn on the SNC 5100 and wait for it to finish
booting.
Step 3.
Step 4.
Step 5.
From the service terminal, type the normalBootcommand.
Wait for the SNC 5100 to reboot.
At the command prompt, continue with the MAP that sent you here.
Special Procedures
This section contains information on special procedures.
Health Check
The Health Check function provides a method to periodically determine the
operational state of an SNC 5100 and its attached interfaces and devices.
Manual Health Check
Health Check is performed manually from the service terminal only if the SNC
5100 is in normal mode.

SNC 5100
Event Log Dump
The events that have been logged in the SNC 5100’s Event Log can be
displayed on the service terminal or viewed from the ADIC Management
Console.
For more information, see the ADIC Management Console User Guide.
This information may be useful because you can see the normal events and any
abnormal events that may lead you to the source of an internal or external
failure.
Each entry contains a sequence number, day, and time-stamp, the event code,
event source (interface name or system process), an index, and a description of
the event.
If the Real Time Clock has been set, the time-stamp will be real time.
Otherwise, the time stamp will be relative to the boot-time.
The Event Log holds more than 2000 events. When the log becomes full, the
oldest events are overwritten by the most recent events.
You can choose to view only those events logged since the SNC 5100 was last
booted or you can view a longer list of events that have accumulated from
previous boots.
You can choose to view events by severity level. Selecting Warning will
display Warning and Notice events. Selecting Information will display
Information, Warning and Notice events.
Retrieving the Code 43 Dump File
If an event code 43 was reported to the ADIC Management Console client, it is
an indication that the SNC 5100 performed an error recovery operation and had
to reset the Fibre Channel interface to clear a lock-up condition.
For more information, see the ADIC Management Console User Guide.

Boot Mode Commands
diagBoot
This command is used only to transition an SNC 5100 from normal operations
to the special diagnostic mode.
Caution
All SCSI and FC cables must be disconnected before entering the
diagBootcommand.
• The diagBoot command first ensures that the /nvfs:mt directory
exists.
• It copies the existing bootline to a file in the /nvfs:mt directory on the
SNC 5100.
• It installs a new bootline directing the SNC 5100 to boot using a special
diagnostic startup script /ffs:mt/diagnstk.rc.
• It renames the persistent map file config/device.mapas
config/device.bak (a new file will be generated after rebooting).
• It issues a rebootcommand to put the changes into effect.
normalBoot
The normalBootcommand is used only to transition the SNC 5100 from the
special diagnostic mode to resume normal operation.
• It restores the bootline that was copied by diagBoot.
• It erases the new persistent device map and renames the original map file
config/device.map – restoring it for use when the SNC 5100 reboots.
• It reboots the SNC 5100.
Diagnostic Commands
This section is a reference for the commands that are available when the SNC
5100 is booted in diagmode.
The command set is limited while in diagmode. You will need to use the
showBoxcommand and three commands (with the suffix Test) when testing
the Ethernet, Fibre Channel, and SCSI interfaces.

POST Error Codes
The Power-On-Self-Test (POST) is responsible for testing the integrity of the
processor’s SDRAM. After testing SDRAM POST will attempt to transfer
control to either the default bootrom image or an alternate image.
POST can also download binary images over the service port and write them to
flash memory. This enables POST to perform a minimal amount of emergency
recovery from FLASH errors.
POST Boot Behavior
ROM Init
Figure 10 ROM Init
After applying power the ERR LED will illuminate.
At this time postInitcode initializes the processor’s internal registers and
subsystems, including the SDRAM controller.
The processor’s internal RAM is used as a tiny-stack for this stage of POST.
Control is then passed to the IpostMainroutine for the SDRAM memory.

This test writes and reads a series of diagnostic patterns to each memory
location in SDRAM. This test is identified by the repeated flash of the SCSI2
LED. This test can take several seconds to complete.
Address Test
Figure 16 Address Test
This test writes and reads address tags to memory to test for bad SDRAM
address lines. This test is identified by the flash of the SCSI3 LED. POST then
relocates itself to SDRAM and moves it’s stack from processor internal RAM
to SDRAM. Control is then transferred to the SDRAM based Secondary POST.
Secondary POST
This stage of POST attempts to locate and execute the intermediate loader, or
“bootrom”. If the operator presses the interrupt button then POST will enter
into the service menu. See the section “POST Service Menu” for details.

POST will examine the FLASH memory primary bootrom locations to
determine whether or not it contains a viable bootrom. If the bootrom appears
valid then POST will transfer control to it. If the bootrom image is considered
invalid then POST will repeat the bootrom checks at the location of the
secondary bootrom. This step is indicated by the flash of the SCSI4 LED.
Start of Bootrom
When POST starts a bootrom image it will display a line like:
Bootrom (*FFF00100)(2)
The number in the first parenthesis is the address of the bootrom’s startup code.
The number in the second parenthesis is flag to the operating system to
determine what type of boot it has – warm or cold.
Bootrom code will set the ERR LED when it reconfigures the PLD.

This will start the ZMODEM transfer engine that transfers a single binary
bootrom image file to POST using the service port. It should not be used to
receive other kinds of binary image files. If the transfer is successful then
POST will program the bootrom image into the FLASH memory device.
While waiting for the file, POST will display:
**B000000023be50
At this point the operator may transfer the bootrom “.bin” file to POST using
the ZMODEM protocol. Refer to terminal emulator documentation for details
on how to do this. After the file is transferred, POST will display:
File transfer and update PASSED
