Filesystem and storage arrays confusion

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.

using multipath -ll you should see an identifier of the storage type:

dm-0 HP,OPEN-V
dm-4 HP,HSV450

Sadly we only have HP storage where I am working.
So above HP is the vendor after the comma is the product.
FYI
OPEN-V is XP storage
HSV450 is EVA
