These units are not assigned an alias for the device unit number by the WWID manager command, therefore, they do not
get a device name and will not show up in a console show dev display.
6.6.1.3 Set the Device Unit Number
The device unit number is a subset of the device name as shown in
a show device console display. For example, in the device name
dga133.1001.0.1.0, the device unit number is 133. The console uses this
device unit number to identify a storage unit. When you set a device unit
number, you are really setting an alias for the device worldwide name. The
64-bit worldwide name is too large to be used as the device unit number,
so an alias is used instead.
This section describes how to use the wwidmgr -quickset command to set
the device unit number for the Fibre Channel disks to be used as the Tru64
