File System and Storage Array Confusion please help

munna529 · 04-01-2014, 11:51 AM

Hi Friends,
I have a host(Suse Linux 10.4) which has 2 luns presented from 2 different arrays HP eva and xp. we are planning to migrate hp eva to 3par. When i look for physical volume i see /dev/dm-4, /dev/dm-5, /dev/dm-7and when i look for multipath -ll i see dm-8,dm-9,dm-7. So i can't confirm which physical volumes or filesystem reside on the EVA array as multipath names are not used in same way during the physcial volume creation. Is there anyother way i can find which file system/Physical volume resides on the EVA array ?
Please, Let me know if you need more information.
Please reply. any help is greatly appreciated.

Sample Output:
From Multipath output i can see storage is coming from 2 different arrays:
dm -6 and dm -7 are coming from EVA and the rest from XP array.

Code:
