vg backup & Restoration in linux

[ManojK_1]

Hi Friends,

We are going to migrate our SAN from EVA5000 to EVA8000.

Two Linux servers are clustered through Service Guard. Before SAN migration i would like to take the VG backup.

How can i achieve that. OS is RHEL4 Update 4. If anybody is having the pre requisite for the SAN Migration.Please help me?

The same way our DB servers also we are planning to migrate (HP Ux 11i v3).DB is oracle 10g, if somebody can help by giving the pre-requisite for both, will be a big help for me.

If you meant the vg configuration backup then "vgcfgbackup". But in Linux the vgcfgrestore a lot more complicated (AFAIK).

Hi Santosh,

Thanks for your reply. The migration is over yesterday night with out any problem.

Anyway for precaution i have taken the vgcfgbackup on linux server.But probe-luns commands has detected the new lun from the migrated SAN with same disk path and vgscan done the rest.

HP unix server also migrated with ORACLE 10g & ASM. So i am closing this thread.
