Tru64 UNIX UDID hexadecimal representations
This section describes UDID representations for storage unit volumes.
The UDID for each volume appears as -1, signifying that the UDID is undefined.
With the supported storage unit LMC, all UDIDs for storage unit volumes are
undefined.
The underscore in Figure 12 highlights the hex string that identifies a storage unit
volume that is attached to an AlphaServer.

console
The third and fourth quartet of the UDID number is always the value "4942-4d20".
This is the string IBM in hex and represents a storage unit volume.
The underscore in Figure 13 highlights an example of a hex string that identifies the
decimal volume number of the storage unit volume. The first three characters of the
next to last quartet of numbers is the hex string representation. Figure 13 shows
that the storage unit volume number is decimal 282.

unit volume on an AlphaServer console or Tru64 UNIX
Figure 14 shows a hex representation of the last 5 characters of the storage unit
volume serial number.

Preparing to boot from the storage unit for the Tru64 UNIX host
system
This section lists the steps you must perform to prepare to boot from the storage
unit.
Use the wwidmgr command to set up each device that you use for booting or
dumping. After you set up a device, the console retains the information that is
needed to access the device in nonvolatile memory. Rerun the wwidmgr command
if the system configuration changes and the nonvolatile information is no longer
valid.
