Compaq AA-RHGWC-TE manual P00 wwidmgr -clear all P00 show wwid

UNIX Version 5.1 installation disk or cluster member system boot disks. Setting the device unit number allows the installation scripts to recognize a Fibre Channel disk.

To set the device unit number for a Fibre Channel device, follow these steps:

1.Use the HSG80 show unit command to obtain the user defined identifier (UDID) for the HSG80 storageset to be used as the Tru64 UNIX Version 5.1 installation disk or cluster member system boot disks. Record the UDIDs. The show unit command also displays the HSG80 disk name, so you can be sure you are using the correct device.

In the example in Table 6–2 the Tru64 UNIX disk is unit D133 with a UDID 133. The UDID for the cluster member 1 boot disk is 131, and the cluster member 2 boot disk is 132.

2.From the AlphaServer console, use the wwidmgr -clear all command to clear the stored Fibre Channel wwid1, wwid2, wwid3, wwid4, N1, N2, N3, and N4 console environment variables. You want to start with all wwidn and Nn variables clear.

P00>>> wwidmgr -clear all P00>>> show wwid*

____________________ Note _____________________

The console only creates devices for which the wwidn console environment variable has been set, and are accessible through an HSG80 N_Port as specified by the Nn console environment variable also being set. These console environment variables are set with the wwidmgr -quicksetor wwidmgr -set wwid commands. The use of the wwidmgr -quicksetcommand is shown later in Example 6–5.

3.Example 6–4 shows the use of the wwidmgr -show wwid command to display the UDID and worldwide names of all devices known to the console. Note that at this time, if you were to issue the show device
