Programming the Flash Memory
The IIR controller normally comes ready to be installed into the computer motherboard
immediately. However, you may need to reprogram the RAID firmware that is located in
the flash memory of the IIR controller.
There are 2 options for programming the firmware, Firmware Update or Firmware
Recovery. Use the Firmware Update procedure to overwrite the existing firmware with a
problems with the flash memory, for example, if the current firmware programmed in the
flash is unusable or if a previous firmware update was inadvertently interrupted (see
2.4
SCSI Termination
Termination is a commonly overlooked requirement when connecting SCSI devices
together. When these devices are connected together, the resulting set of devices is
typically referred to as a SCSI bus. SCSI devices such as hard disks and tape drives must
be terminated if they are the last physical devices at either end of the SCSI bus (if nothing
else is actively terminating the end of the bus such as a terminator or backplane). If a
device is inserted into the middle of the SCSI bus, then it (the device itself) should not be
terminated. Only terminate each end of the bus. The modular RAID on motherboard
(MROMB) design lowers cost by utilizing the SCSI controller and connectors that are
integrated into the system’s motherboard. With MROMB, termination occurs on the host
SCSI controller.

After Ultra2 all new speeds are wide only.
3.3.2
Support for Non-Hard-Disk-Drive SCSI Devices (Non-Direct-
Access Devices)
The RAID controller will pass through to the host operating system direct access to non-
direct-access SCSI devices which are connected to a SCSI bus (channel) of the RAID
controller. The RAID controller passes through all control of these devices to the host
operating system.
Types of supported non-Direct-Access SCSI devices (this does not cover specific vendors
and models):
• SAF-TE Processors
• Tape Backups
• CD-ROMs
3.4
RAID Array Drive Roaming
Array Roaming allows the user the ability to move a complete RAID array from one
computer system to another computer system and preserve the RAID configuration
information and user data on that RAID array. ††Compatible RAID controllers must
control the RAID subsystems of the two computer systems (see list of compatible
controllers in this section). The transferred RAID array may be brought online while the
target server continues to run if the hard disk drives and disk enclosure support hot plug
capabilities; however, not all operating systems support this feature. The hard disk drives
are not required to have the same SCSI ID in the target system that they did in the original
system that they are removed from. The RAID array drive that is being roamed must not
be of type Private. This includes all non-private host, array, and logical drives.
20
Hardware Installation and User’s Guide
Hardware Specifications and Features
Warning: †† The SRCMRU adapter, with firmware 2.34.yy-Rzzz, is not compatible with all
previous controllers and firmware versions. Do not attempt RAID Array Drive
Roaming between RAID controllers that are not compatible with the SRCMRU
controller. Unpredictable behavior may include, but is not limited to, data loss or
corruption.
Compatible controllers include:
• SRCU42L – Firmware version 2.34.yy-Rzzz
• SRCU31LA - Firmware version 2.3x.yy-Rzzz
• SRCU31A– Firmware version 2.3x.yy-Rzzz
• SRCU32 – Firmware version 2.3x.yy-Rzzz
• SRCMRU – Firmware version 2.3x.yy-Rzzz
• SRCZCR – Firmware version 2.3x.yy-Rzzz
Note: Compatibility refers only to how data and RAID configuration information are written to
the hard disks. Compatible adapters have the same data file format.

RAID Controller Drive Limitations (Host, Array,
Logical, and Physical)
The following are limitations assuming the following:
• U160 or U320 speed depending on the SCSI controller on the motherboard
• Dual channel SCSI controller
• Cabling that meets U160 or U320 specifications depending on the SCSI controller
Physical drives are limited by the number of SCSI channels being controlled by the
RAID controller. The firmware/software supports a maximum of 15 hard disk drives per
channel (or 14 if one SCSI ID is being occupied by an intelligent enclosure processor).
The maximum number of array drives is limited to 35 by the RAID firmware. The actual
supports channel spanning where an array can consist of physical drives that are attached
to either one or to both channels of the RAID controller. An array drive requires a
minimum of two hard disk drives (or logical drives). Therefore the maximum array
limitation for each RAID controller is the physical drive limit of that RAID controller
divided by two. An array drive can contain (or have reside on it) up to a maximum of 2
host drives.
Hardware Installation and User’s Guide
21
Hardware Specifications and Features
RAID firmware limits the controller to a maximum of 30 host drives (RAID volumes) per
controller. There is a minimum of at least one host drive per array drive. A host drive can
only be associated with (or reside on) a single array drive. Like array drives, host drives
can reside on hard disk drives that are isolated to a single channel or span both of the
channels of the RAID controller.

Firmware Update Procedure via XROM StorCon
The Storage Console (StorCon) is a full-featured monitoring and configuration utility with
a text-based user interface. StorCon manages all aspects of the RAID subsystem as well as
many features of the RAID adapter. Refer to the Software Guide for more details about
StorCon.
You can use StorCon to update the firmware image. The menu option, Firmware Update,
allows you to update the firmware, BIOS and expansion ROM (XROM) StorCon
currently programmed on the flash memory of the IIR controller. Because the Flash-RAM
can be reprogrammed many times, the software modules can be easily updated, without
having to remove the controller from its PCI slot.
The firmware, BIOS and XROM StorCon are part of the file, SRC_RXFW.xxx, where the
file extension xxx indicates the version stepping. The current firmware file can be found
on the RAID Software Suite CD-ROM. To get the latest firmware for the IIR controller,
Note: The Firmware Update option is not available when StorCon is accessing the IIR
Controller remotely.
