LVM export in RedHat 5.5-6.1 1

[neuralnode]

Hi All,

Setup: 2 RedHat 5.5 servers with Oracle 10g installed, each server in a different Datacenter.

Situation: Datacenter A goes down. Server A is no longer available, but the DB is critical. The storage from server A containing the DB filesystems is replicated and connected to Server B in Datacenter B.

Task: Configure the newly connected disks on server B, so that the LVM structure is preserved, and the DB filesystems can be mounted.

How do I do that??

I'm not really experienced with RH. On Solaris the easiest way is to import/export a ZFS pool.
What would be the equivalent operation on RedHat with LVM?

Thanx in advance!

Thanx, BadBigBen!

Still, I'd have one more question. What if both machines have the same VG and LV names? Can I force the import of a VG under a new name?

to tell you the truth, I've no idea, I had only done this once a few years back, and it was just to upgrade the hardware...

I would think that either using unique names or just remounting them on new hardware and then transferring/backing-up data, is the key to success...
