• 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

• dgb132.1004.0.2.0
• 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).
