Compaq AA-RHGWB-TE manual Using Fibre Channel Storage

•After a cluster member has been added to the cluster with clu_add_member (but before the member system is booted).

_____________________ Note _____________________

You do not use this procedure after using clu_create to create the first cluster member. Before booting the first cluster member, you reset the bootdef_dev console environment variable to multiple boot paths.

To set the bootdef_dev console environment variable when booting from a Fibre Channel device, follow these steps:

1.Obtain the device name for the Fibre Channel units that you will boot from. Ensure that you choose the correct device name for the entity you are booting (Tru64 UNIX, cluster member system 2, and so on). They show up in the reachability display as shown in Example 6–3 with a Yes under the connected column. You can also use the wwidmgr -show reachability command to determine reachability. Example 6–4 provides the display for a show dev command, which shows the device names of devices that may be assigned to the bootdef_dev console environment variable. Example 6–3 and Example 6–4 show that the following device names can be used in the bootdef_dev console environment variable as possible boot devices:

•dga131.1002.0.1.0

•dga131.1004.0.1.0

•dga132.1002.0.1.0

•dga132.1004.0.1.0

•dga133.1002.0.1.0

•dga133.1004.0.1.0

•dgb131.1002.0.2.0

•dgb131.1004.0.2.0

•dgb132.1002.0.2.0

•dgb132.1004.0.2.0

•dgb133.1002.0.2.0

•dgb133.1004.0.2.0

Note that each of the storage units are reachable through four different paths, two for each host bus adapter (the Yes in the connected column).
