If you flash the light on a storage unit (logical disk) that is a mirrorset,
stripeset, or RAIDset, the lights on all disks in the storageset will blink.
Record the /dev/disk/dskn value (dsk15) for the Tru64 UNIX disk that
matches the UDID (133) (Table 6–2).
Complete the installation, following the instructions in the Tru64 UNIX
Installation Guide.
After the installation is complete, reset the bootdef_dev console
environment variable to provide multiple boot paths (see Section 6.8).
6.8 Resetting the bootdef_dev Console Environment
Variable
If you set the bootdef_dev console environment variable to multiple paths
in Section 6.6.3, the base operating system installation, clu_create,or
clu_add_member procedures modify the variable and you should reset it to
provide multiple boot paths.
To reset the bootdef_dev console environment variable, follow these steps:
1. Obtain the device name and worldwide name for the Fibre Channel
units that you will boot from (see Table 6–2). Ensure that you choose
the correct device name for the entity you are booting (Tru64 UNIX,
cluster member system 2, and so on).
2. Check the reachability display (Example 6–3) provided by the wwidmgr
-quickset or the wwidmgr -reachability commands for the device
names that can access the storage unit you are booting from. Check the
show dev command output to ensure the device name may be assigned
to the bootdef_dev console environment variable.
____________________ Notes ____________________
You should choose device names that show up as both Yes
and No in the reachability display connected column. Keep
in mind, that for multiple-bus failover, only one controller is
normally active for a storage unit. You must ensure that the
unit is reachable if the controllers have failed over.
If you have multiple Fibre Channel host bus adapters, you
should use device names for at least two host bus adapters.
