Which SAN disk is which?

Really simple one this : SAN disk provided, but you don’t know which one is which and you don’t yet have any details from your storage team of LUN device numbers that you might be able to look up. Some, or all of the disks need to be left raw, i.e. not added to a volume group.

Assuming the disks provided are different sizes, you might get some indication using something like:

for i in $(lspv | awk '{print $1}')
do
   echo $i : $(getconf DISK_SIZE /dev/$i)
done

Hopefully, that will give you a clue.
