6.6.1.3 Set the Device Unit Number
The device unit number is a subset of the device name as shown in
ashow 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 analias forthe device worldwidename. 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
