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 1 highlights the hex string that identifies a storage unit volume that is attached to an AlphaServer.

01000010:6000-1fe1-4942-4d20-0000-0000-2821-5660

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 2 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 2 shows that the storage unit volume number is decimal 282.

Figure 3 shows a hex representation of the last 5 characters of the storage unit volume serial number.
