Chapter 1. Implementing Fibre Channel host adapter cards 19
1.6.2 Compaq Tru64 UNIX Version 4.0x host system
In this topic we explain how to install and configure a Tru64 UNIX Version 4.0x
host system. Before you configure the ESS volumes, ensure that the system and
Fibre Channel adapter cards are at the minimum supported firmware revision.
1.6.3 Verifying the Compaq configuration
The following procedures tell you how to verify the configuration for the host
adapter cards and firmware for a Compaq host system:
1. From the console prompt, type show version
This is an example of what you see when you type the show version
command.
version V5.8-2, 21-Jul-2000 17:16:08
2. Type #view /var/adm/messages to display the log file that shows the system
version and the version of the Fibre Channel adapter cards.
This is an example of how the firmware version and the host adapter is
displayed

1.6.4 Operating system device recognition
You can access the disks in the special files. You can find the special files in the
/dev directory. The disk block special file starts with rz and the character disk
special file starts with rrz. Compaq Tru64 UNIX uses the following syntax to
identify the disk special files:
[r] rz [L] [B] [P]
In this syntax:
򐂰 [L] — LUN letter. If the LUN is 0, no letter is specified for the LUN. You can
specify LUNs 2 - 7 for letters b - h.
򐂰 [B] — Bus number multiplied by 8 plus the target number
򐂰 [P] — Disk partition from a - h
Following is an example of the output that is displayed from boot log or the scu
show edt command). This shows a disk at LUN 0, bus SCSI 16, target 0.
[r]rz[LUN 0][16 * 8 + 0][a-h] = rz128a, rz128b, rz128c, rz128d, rz128e, rz128f,
rz128g, rz128h,rrz128a, rrz128b, rrz128c, rrz128d, rrz128e, rrz128f, rrz128g,
rrz128h
