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.
6.6.2 Setting the Device Unit Number
Set the device unit number for the Fibre Channel disks to be used as the
Tru64 UNIX Version 5.0A installation disk and cluster member boot disks.
Setting the device unit number allows the installation scripts to recognize
a Fibre Channel disk. You have to set the device unit number because the
64-bit worldwide name is too large to be used as the device unit number.
When you set the device unit number, you set an alias for the device
worldwide name.
You use the WWID manager (wwidmgr) to define a device unit number that
is an alias for Fibre Channel devices. For instance, if DKA0 or DKA100 are
part of the device name seen in a show dev display, 0 or 100 is the device
unit number.
To set the device unit number for a Fibre Channel device, follow these steps:
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
member system boot disks. In the example in Table 6–2 the Tru64 UNIX
