The number within the brackets ([ ]) is the item number of the
device shown on any particular line.

The UDID is assigned at the HSG80 with the set Dn 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.

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).

The console environment variable set for this worldwide name.
Only 4 wwidn console environment variables (wwid0, wwid1,
wwid2, and wwid3) can be set. The console show dev command
only shows those disk devices for which a wwidn console
environment variable has been set using the wwidmgr -quickset
