SCSI Cabling  
You can daisy chain up to 15 devices on the SunSwift SBus Adapter as follows:  
Wide-to-wide devices  
Use a 68-pin to 68-pin cable.  
Always put wide SCSI devices closest to the host system.  
Use a 68-pin to 50-pin cable.  
Wide-to-narrow devices  
You can include only one wide-to-narrow cable along a  
chain of peripherals.  
Always put the narrow SCSI devices at the end of the  
chain.  
The SCSI bus must be terminated at the end of the chain.  
Single byte data transfers from an odd memory address to a SCSI device are  
not supported by the SunSwift SBus Adapter SCSI-2 (fas) device. Refer to  
SMCC Open Issues Supplement Solaris 2.5 Hardware: 1/96 for more detailed  
information.  
If you use the SunSwift SBus Adapter for SCSI purposes only, you must  
change the device name from SUNW,hmeto SUNW,hme_idleto avoid a  
Link Down — cable problem?message. Refer to SMCC Open Issues  
Supplement Solaris 2.5 for more detailed information.  
Ethernet Cabling  
An additional Ethernet cable is required if you want to use your systems  
existing Ethernet interface and the SunSwift SBus Adapter Ethernet interface.  
Disabling Your Current Ethernet Device  
If you remove your systems existing Ethernet cable (either from its on-board  
Ethernet device or from an existing Ethernet card) and insert it into the  
SunSwift SBus Adapter Ethernet connection, you must disable your current  
cards Ethernet device. For example, if your current Ethernet device is called  
le0, you would remove its IP address and hostname from the /etc/hosts  
file and remove the /etc/hostname.le0file itself.

3.1 Preparing for Software Installation  
Note – If the CD-ROM drive that you are using for software installation is  
attached to a remote machine, refer to your SunOS installation guide for  
remote CD-ROM access.  
For Solaris 2.5 Systems  
Some newer systems are pre-loaded with the SunSwift SBus Adapter driver  
(hme). Before installing the driver from the CD-ROM, perform the following  
task.  
As superuser, check for the hmedriver and its revision number by using  
the modinfocommand:  
# modinfo | grep hme  
You should see a line similar to the example below if the driver is already  
installed:  
51 50270000 9f78 7 1 hme (FEPS Ethernet Driver v 1.40)  
If the revision number is 1.40 or above, your system already has the  
SunSwift SBus Adapter driver, and loading from the CD is unnecessary.  
If the revision number is below 1.40, or nothing is displayed as a result of  
the modinfocommand, install the software from the CD-ROM that came  
with the SunSwift SBus Adapter. (See below).  
Installing Software From the CD-ROM for Solaris 2.4 and 2.5  
Install the software drivers from the CD-ROM that came with the  
SunSwift SBus Adapter. Refer to the CD-ROM documentation that came  
with your adapter for driver installation instructions  
(Part No: 804-5303-10).

3.2 Net-Install of Solaris 2.4 Over the hmeInterface  
This section is only applicable if you are installing Solaris 2.4 on a net-install  
client system over the SunSwift SBus Adapter (hme) interface.  
Note – The Solaris 2.4 CD-ROM cannot be used to perform a net-install (read  
only), thus the Solaris 2.4 CD image archive is required to update certain  
SunSwift SBus Adapter files.  
Updating the Solaris 2.4 Archive to Use the hmeInterface  
1. Determine the directory where the CD image is located on the boot server.  
For example, if the Solaris software is located within a directory named  
DIR, change to the root partition of the client being installed by typing:  
# cd DIR/export/exec/kvm/<archive_of_arch>/etc  
The / etc/bootparamsfile will point you to the clients root partition.  
2. Edit the name_to_majorfile by adding an entry for the SunSwift SBus  
Adapter device (hme).  
If the major device number for the last file entry is nthen use n+1for the  
hmechannel major device number. As shown in the example below, if the  
last entry for the major device number is 108, use 109for the hmedevice.  
# llcl 107  
# audiocs 108  
# hme 109  
3. Copy the hmedriver from the SunSwift SBus Adapter CD-ROM to the  
clients root partition as follows:  
# cp /cdrom/sunswift_1_0/2.4/SUNWhmd/reloc/kernel/drv/hme \  
DIR/export/exec/kvm/<archive_of_arch>/kernel/drv  
4. On the client system, perform the tasks in Section 3.5.3, “Booting From  
the Network Using Solaris 2.4.”

5. Complete the client installation. Refer to your Solaris documentation for  
detailed instructions.  
6. Reboot the system.  
7. Install the software drivers from the CD-ROM that came with the  
SunSwift SBus Adapter. Refer to the CD-ROM documentation that came  
with your adapter for driver installation instructions  
(Part No: 804-5303-10).  
3.3 Host File Configuration  
After installing the SunSwift SBus Adapter software, you must create a  
hostname.hme<num> file for its Ethernet interface. You must also create both  
an IP address and a hostname for its Ethernet interface in the /etc/hostsfile.  
To prepare your system for the SunSwift SBus Adapter:  
1. Create a /etc/hostname.hme<num> file, where <num> refers to the  
number of each SunSwift SBus Adapter channel you plan to use. For  
example, use channel hme0for the first card; use channel hme1for a  
second card.  
Do not create /etc/hostname.hme<num> files for SunSwift SBus Adapter  
channels you plan to leave unused. The /etc/hostname.hme<num> file  
must contain the hostname for the appropriate network interface.  
The hostname should have an IP address and should be entered in the  
/etc/hostsfile.  
The hostname should be different from any other hostname of any other  
interface, for example: /etc/hostname.le0and /etc/hostname.hme0  
cannot share the same hostname.  
Following is an example of the /etc/hostname.hme<num> files required  
for a machine called zardozthat will be known as zardoz-11and  
zardoz-12on the networks connected to the hme0and hme1Ethernet  
interfaces.  
zardoz # cat /etc/hostname.hme0  
zardoz-11  
zardoz # cat /etc/hostname.hme1  
zardoz-12

2. Create an appropriate entry in the /etc/hostsfile for each active hme  
channel.  
Using the example in step 1, you will have:  
zardoz # cat /etc/hosts  
...  
127.0.0.1  
localhost  
129.144.10.57 zardoz  
129.144.11.83 zardoz-11  
129.144.12.41 zardoz-12  
loghost  
3.4 Caution: Package Dependency  
Caution – There is a package dependency with the SunSwift SBus Adapter.  
Before proceeding, perform the following task.  
!
As superuser, check for the adapter packages by using the pkginfo  
command:  
# pkginfo | grep SUNWhmd  
If you see lines containing SUNWhmdl and SUNWhmdlu and lines  
containing SUNWhmd and SUNWhmdu, then do not remove any of these  
packages from your system.

applies to your specific needs.  
3.5.1 Booting From the Network Using Solaris 2.5  
To use the SunSwift SBus Adapter Ethernet interface as the boot device for  
Solaris 2.5 systems, perform the following tasks.  
1. At the okprompt type:  
ok show-devs  
The show-devscommand lists the system devices. You should see the full  
path name of the hmedevice, similar to the example below:  
/iommu@f,e0000000/sbus@f,e0001000/SUNW,hme@3,8c00000

3.5.2 Diskless Client Booting for Solaris 2.4  
In order to boot a diskless client with a local SunSwift SBus Adapter interface  
(hme) on a Solaris 2.4 system, the following tasks must be performed on the  
boot server.  
1. Go to your clients root partition by typing the following:  
# cd /export/root/<client name>/etc  
2. Edit the name_to_majorfile by adding an entry for the SunSwift SBus  
Adapter device (hme).  
If the major device number for the last file entry is nthen use n+1for the  
hmechannel major device number. As shown in the example below, if the  
last entry for the major device number is 104, use 105for the hmedevice.  
# qec 103  
# qe 104  
# hme 105  
3. Copy the hmedriver from the CD-ROM to the clients root partition as  
follows:  
# cp /cdrom/sunswift_1_0/2.4/SUNWhmd/reloc/kernel/drv/hme \  
/export/root/<client name>/kernel/drv/hme  
4. Create a hostname.hme<num> file for the client in the /etcdirectory in  
the clients root partition.  
Proceed to Section 3.5.3, “Booting From the Network Using Solaris 2.4” for the  
client system.

3.5.3 Booting From the Network Using Solaris 2.4  
The device name of newer SBus cards for Solaris 2.5 is identified by a  
“SUNW,” prefix. If your system is running Solaris 2.4, it will not recognize the  
device. Perform the following tasks to set up your system so the device driver  
can recognize the SunSwift SBus Adapter.  
1. At the okprompt type:  
ok setenv use-nvramrc? true  
ok show-devs  
The show-devscommand lists the system devices. You should see the full  
path name of the hmedevice, similar to the example below:  
/iommu@f,e0000000/sbus@f,e0001000/SUNW,hme@3,8c00000  
2. Type:  
ok nvedit  
3. Type the following exactly as shown, spaces and quotation marks  
included, pressing the Return key at the end of lines 0, 1and 2:  
0: probe-all install-console banner  
1: cd (full path name of the hme device)  
2: “ hme” nameprop  
3: device-end  
4. Press the Control-C keys after typing device-end.  
5. At the okprompt, type:

3.6 Post-Installation Procedures (Optional)  
Perform the tasks in the following sections to verify and customize the  
performance of the SunSwift SBus Adapter.  
3.6.1 Using Hubs That Do Not Send Link Pulses  
Certain hubs are not compliant with the IEEE 802.3 Ethernet standards for link  
pulses, therefore do not send link pulses. To connect your system to these non-  
compliant hubs, you need to disable your system from looking for link pulses.  
1. At the okprompt type:  
ok show-devs  
The show-devscommand lists the system devices. You should see the full  
path name of the hmedevice, similar to the example below:  
/iommu@f,e0000000/sbus@f,e0001000/SUNW,hme@3,8c00000  
2. Type:  
ok nvedit  
3. Type the following, pressing the Return key at the end of line 0:  
0: probe-all install-console banner  
1: apply disable-link-pulse (full path name of the hme device)  
4. Press the Control-C keys after typing (full path name of the hme device).  
5. At the okprompt, type:  
ok nvstore  
ok setenv use-nvramrc? true  
6. Reboot your system.

3.6.2 Configuring Driver Parameters  
The hmedevice driver, which is loaded from the CD-ROM, controls the  
SUNW,hmeEthernet device. The device driver automatically selects the link  
speed using the auto-negotiation protocol with the link partner. (See  
Section 3.6.5, “Auto-Negotiation.”)  
You can manually configure the hmedevice driver parameters to customize  
each SUNW,hmedevice in your system in one of three ways:  
Configure the hmedriver parameters generally for all devices in the system  
by entering the parameter variables in the /etc/systemfile.  
Set a parameter on a per-device basis by creating the hme.conffile in the  
/kernel/drvdirectory.  
Use the nddutility to temporarily change a parameter. This change is lost  
when you reboot the system.  
3.6.3 Increasing 100BASE-T Performance  
The 100BASE-T performance of the SunSwift SBus Adapter can be increased by  
changing the TCP hiwater marks to 64K. This can be done with the nddutility  
as follows.  
1. As superuser type:  
# ndd -set /dev/tcp tcp_xmit_hiwat 65535  
# ndd -set /dev/tcp tcp_recv_hiwat 65535  
# ndd -set /dev/tcp tcp_cwnd_max 65534  
The changes will take effect immediately.

3.6.4 Forcing Network Speed Between 10 Mbps and 100 Mbps  
1. At the okprompt, use the show-devscommand to list the system devices.  
You should see the full path name of the hmedevice, similar to the example  
below:  
/iommu@f,e0000000/sbus@f,e0001000/SUNW,hme@3,8c00000  
2. Type:  
ok nvedit  
3. Type the following, pressing the Return key at the end of line 0:  
0: probe-all install-console banner  
1: apply transfer-speed=10 (full path name of the hme device)  
4. Press the Control-C keys after typing (full path name of the hme device).  
Note – In the above example, the speed is forced to 10 Mbps. To force the  
speed to 100 Mbps, replace 10 with 100.  
5. At the okprompt type:  
ok nvstore  
ok setenv use-nvramrc? true  
6. Reboot your system.  
Refer to the Platform Notes: The hme Fast Ethernet Device Driver document (Part  
No: 802-3970) for more information on the hmedevice driver and forcing  
network speed. This document is also available on the Solaris 2.5 and the  
Solaris 2.5: 1/ 96 AnswerBook.

3.6.5 Auto-Negotiation  
A key feature of the SunSwift SBus Adapter is auto-negotiation. The auto-  
negotiation protocol, as specified by the 100BASE-T standard, automatically  
selects the operation mode (half-duplex or full-duplex) and speed (10 Mbps or  
100 Mbps) for the adapter.  
The hmedevice driver operates the SUNW,hmedevice by default in half-duplex  
mode only.  
If the SunSwift SBus Adapter is connected to a remote system or interface that  
is not capable of auto-negotiation, your system automatically selects the speed  
and half-duplex mode.  
If the SunSwift SBus Adapter is connected to a link partner with which the  
auto-negotiation protocol fails to operate successfully, you can configure the  
device to not use this protocol and force the driver to set up the link in the  
mode and speed of your choice.  
Refer to the Platform Notes: The hme Fast Ethernet Device Driver document (Part  
No: 802-3970) for more information on the hmedevice driver and auto-  
negotiation. This document is also available on the Solaris 2.5 and the Solaris  
2.5: 1/ 96 AnswerBook.

Note – For Solaris 2.5 diagnostics testing, refer to the SunVTS 1.0 Users Guide.  
A.1 Sundiag  
Sundiag is an on-line system exerciser that runs diagnostic hardware tests. It is  
used primarily with the OpenWindows software interface that enables you to  
quickly and easily set test parameters to run tests.  
Note – Sundiag does not probe for SunSwift SBus Adapter devices by default.  
For Sundiag to acknowledge an hme<num> channel, the .usertestfile must  
be edited before bringing up Sundiag, as described in the following section.  
A-1  
Download from Www.Somanuals.com. All Manuals Search And Download.  
A
A.1.1 Editing .usertestFile  
1. Login as superuser and then type the following:  
zardoz# cd /opt/SUNWdiag/bin  
2. Edit the file .usertestby adding the following line wherein the format  
is test label, test name, and command-line arguments.  
The example given is for a single hme0interface; for multiple channels add  
an additional line for each channel using hme1, hme2, etc.:  
hme0, nettest, IF=hme0 v  
Because testing the SunSwift SBus Adapter is user defined, default options  
are not displayed in Sundiag. Test options for an hme<num> channel can be  
defined in the .usertestfile using the command nettest. Type the  
command nettestwithout arguments for a list of options, for example:  
zardoz# nettest  
Usage: nettest [TARGET=h1+h2...] [IF=interface] {TEST=0..7}  
N=nopkts} {P=pattern} [T=seconds]  
A.1.2 The Sundiag Window  
Note – Examples in this section show Sundiag running in the OPEN LOOK®  
environment. Sundiag run in the SunView™ environment will look different.  
To start Sundiag, cdto the Sundiag directory  
(/opt/SUNWdiag/bin/sundiag) and then type the sundiagcommand.  
After you enter the sundiagcommand, the Sundiag window is displayed on  
your screen, refer to Figure A-1. This window is the primary interface for  
running Sundiag. Refer to the Sundiag manual that came with your operating  
system for further details.
