I have a list of LUN ID, my task is to find if disk has been added or not. How do I do that? I have been searching the forum and not able to find answer.

thanks

Hi,
it would be helpful if you could let us know which OS and what kind of storage you're using ?
Kind regards

look the LUN ID is supposed to be the number here:

for example:
c3t18d51s2

LUN ID = 51, because it is d51 (disk #51).

but be careful, it's tricky.

I suggest you trace your disks.

It seems that you have two controller (c3, c4)

and on C3, you have three targets:
t4, t14, t18

(PS: for detailed description, check your SAN to figure out why they appear as 3 targets, but that's not really important)

now your LUNs appear to be out of order:
d39, d40
d104,
d150, d151, d154

so try to MAP each LUN on your SAN to each d#..

I hope that helps !

ok, I see. I will give a try tomorrow. Thanks
