1
The number within the brackets ([ ]) is the item number of the
device shown on any particular line.
2
The UDID is assigned at the HSG80 with the
set D n IDENTIFIER
= xxx
command, and is not used by the Tru64 UNIX operating
system, but may be set (as we have done with the
SET D131
IDENTIFIER=131
group of commands). When the identifier is not
set at the HSG80, a value of -1 is displayed.
3
The worldwide name for the device. It is prefixed with the value
WWID:01000010:
. The most significant 64 bits of the worldwide
name resembles the HSG80 worldwide name, and is assigned when
the unit is manufactured. The least significant 64 bits is a volume
serial number generated by the HSG80. You can use the HSG80
SHOW unit
command to determine the worldwide name for each
storage unit (as shown in Example 6–2).
4
The console environment variable set for this worldwide name.
Only 4
wwid
<
n
> console environment variables (wwid0, wwid1,
wwid2, and wwid3) can be set. The console
show dev
command
only shows those disk devices for which a
wwid
<
n
> console
environment variable has been set using the
wwidmgr -quickset
or
wwidmgr -set
command. In this example, none of the
wwid
<
n
>
environment variables is set.
4. Look through the
wwidmgr -show wwid
display and locate the UDID
for the Tru64 UNIX disk (133) and each member system boot disks (131,
132) to ensure the storage unit is seen. As a second check, compare the
worldwide name values.
5. Example 6–3 shows the use of the
wwidmgr
command with the
-quickset
option to define the UDID as the device unit number as an
alias for the worldwide name for each of the devices. The
wwidmgr
-quickset
utility sets the device unit number and also provides a
display of the device names and how the disk is reachable (reachability
display).
Example 6–3 shows:
• The use of the
wwidmgr -quickset
command to set the device unit
number for the Tru64 UNIX Version 5.0A installation disk to 133,
the cluster member system boot disks to 131 (cluster member 1) and
