Same disks, different HW paths

[PSS SYS ADMIN]

Hi everyone,
I would upgrade my EMC storage with a new pair of fc card.
This storage is connected to an L2000 via 2 fc in alternate link.
Can you suggest a failsafe, fast procedure to upgrade my LVM configuration without any risk?
The vg00 is on internal disks, so I must upgrade the other vgs.

Regards...
PSS

Hi,
Are you using volume logix?
because wwn number of the fc card changes with different card.
If you install the new card in same slot then hw path may not change.In case it is changes then do a vgexport and vgimport with -s options
vgexport -v -m /tmp/vgxx.map -s /dev/vgxx
then do a vgimport
mkdir /dev/vgxx
mknod ....
vgimport -v -m /tmp/vgxx.map -s /dev/vgxx
