How to move VG configuration from one machine to another?

dictum9 — Fri, 17 Mar 2017 15:52:34 GMT

I have cloned one machine to another via Ignite. It only took care of the vg00 volume group. I still need to restore Oracle volume groups. What is the best way to accomplish that?

The disk names (LUNs) are different on both machines. Would it be easier to recreate the volume groups manually? vgcreate/vgextend/lvcreate? Just wondering if there is a shortcut. with vgcfgbackup. But how do I get it to understand that all the LUN definitions are new?

Both machines are 11.31/rx8640

do you want to move the disks to the new system with data in place?

No, I don't want to move the disks. the machine is a clone and the disks defined on it have different names. The LUNS presented to the old computer can only be presented there.

You have to be more specific about what you need to do here.

Do you want to make the LVM layout (VG/LV names and mountpoints) the

same on both servers? Once you have presented the new LUNs to the new

(clone) server, you can recreate the LVM structure to match the old server.

Yes, you have to recreate the volume groups via vgcreate/vgextend/lvcreate for your particular case.

On a different occassion, let's say you have a snaphot ( via storage system ) of the LUNs of the non vg00's, you can do a -

# vgimport -m <mapfile> <new_vgname> < new_CTD_of_the LUN>

Cheers!!
