aTheseunits are not assigned an alias for the device unit numberbythe WWID manager command, therefore, they do not
geta device name and will not show up in a console show devdisplay.
6.6.2 Setting the Device Unit Number
Set the device unit number for the Fibre Channel disks tobe used as the
Tru64UNIX Version 5.0A installation disk and cluster memberboot disks.
Setting the device unit number allows the installation scripts to recognize
a Fibre Channel disk. You have to set the device unit number becausethe
64-bit worldwide name is too large to be used as the device unitnumber.
When you set the device unit number,you set an alias for the device
worldwide name.
Youuse the WWID manager (wwidmgr) to define a deviceunit number that
is an alias for Fibre Channel devices. For instance, if DKA0or DKA100 are
part of the device name seen in a show dev display, 0 or 100 is the device
unit number.
Toset the device unit number fora Fibre Channel device, follow thesesteps:
1. Obtain the user define identifier (UDID) for the HSG80 storageset to
be used as the Tru64 UNIX Version 5.0A installation disk or cluster
membersystem bootdisks. Inthe example in Table 6–2 the Tru64 UNIX
