Compaq AA-RHGWC-TE manual Displaying the Available Boot Devices, P00 show wwid

The disks are not reachable and you cannot boot until after the system is initialized.

If you have not set the UDID, you cannot set the device unit number as shown in Example 6–5. You have to use the quickset command with the item number displayed by the wwidmgr -show wwid command (see Example 6–4). For instance, to set the device unit number of item number 17 of Example 6–4 to 770, use the following command:

P00>>> wwidmgr -quickset -item 17 -unit 770

The device names have also been set for the Tru64 UNIX disk and first cluster member system boot disks. Record these device names for for later use.

In the reachability portion of the display, the storagesets are reachable from KGPSA pga through two HSG80 ports and from KGPSA pgb through two HSG80 ports. Also, the device unit number has been set for each KGPSA to HSG80 controller port connection, even if the storage unit is not currently reachable via that connection.

6.6.1.4 Displaying the Available Boot Devices

The only Fibre Channel devices displayed by the console show dev command are those devices that have been assigned to a wwidn environment variable with the wwidmgr -quicksetcommand.

The devices shown in the reachability display of Example 6–5 are available for booting and the setting of the bootdef_dev console environment variable during normal console mode.

If you were to execute the show wwid* console command now, it would show that the environment variable wwidn is set for two disks. Also, the show n* command shows that the units are accessible through four HSG80 N_Ports as follows:

P00>>> show wwid*

wwid0	133 1	WWID:01000010:6000-1fe1-0000-0d60-0009-8080-0434-002e
wwid1	131 1	WWID:01000010:6000-1fe1-0000-0d60-0009-8080-0434-002f
wwid2
wwid3
P00>>> show n*
N1		50001fe100000d64
N2		50001fe100000d62
N3		50001fe100000d63
N4		50001fe100000d61

Example 6–6 provides sample device names as displayed by the show dev command after using the wwidmgr -quicksetcommand to set the device unit numbers.
