[Veritas-bu] SAN drive persistent binding with JNI

Joe

I use a FC64-1063, instead of a FCI-1063, but the procedure's probably
the same.

I'd suggest downloading the JNI EZIfibre config gui from their website.
This will allow you to specify the target numbers for each binding and
assign them permanently.

Otherwise, you'd need to add the entries to /kernel/drv/fcaw.conf
manually, using info from /var/adm/messagess (tricky to do; better to
use the gui).
