SUMMARY: disk drive model# from shell? Fibre Channel problems...

The feelings about a5200 were mixed, some said "we never had such
problems", others said "a single disk failure causes the entire disk array
to fail", and Sun is of course, helpless..


There seem to be a couple of tools that can display disk model #:

./ -v disk
which can be found at

there is also a 3rd party tool called  scsiinfo

But I didn't really look into either of those.
Apparently you can use luxadm display <enc>,disk to get that info
But even better you can use 
iostat -En (was told works on sol8,9, but worked on 7 as well).
(it's better, b/c it's faster)

Anyway, before I got the last answer, I already used luxadm display:

for a in a b c d; do   for b in f r ; do  for i in 0 1 2 3 4 5 6 7 8 9 10
;do printf "array: $a disk: $b,$i "; luxadm display $a,$b$i|grep Pr
oduct| awk '{print $3}';done;done; done;

For their kind answers/suggestions.
