We have a 2-node cluster version 6.1. Running 7 oracle dbs. Everything is on symmetrix. We are going to have a storage migration from one array to another. There will be SRDF setup between two arrays. I will be getting all the luns from new array. I am just looking for the cluster steps for this migration to be successful. Can someone please share the overall steps to achieve this to avoid any corruption or cluster in consistent state and working properly.
You can do it with storage methods (SRDF), but i would do it with simple AIX means. This method will require no downtime at all, you can do everything during service time:
- Create new LUNs from the new storage equal in size to the set of disks you use now and let the "cfgmgr" run on both nodes.
- Then add the new disks to their pairwise counterparts on th active node ("extendvg") and use "mirrorvg" to set up a new mirror.
- When the disks are synced do a "importvg -L" (learning import) on the inactive node from the old disks.
- On the active node do a "unmirrorvg" and a "reducevg" to the old disks.
- On the inactive node do a "importvg -L" again, this time from the new disks. VG information is now consistent again.
- remove old disks from the configuration. Once you have them physically disconnected run "cfgmgr" again on both nodes.
Here is an example run: vg1 has 1 disk "hdisk1" (100G) from the old storage.
Create a new LUN from the new storage, which is 100G too. Run "cfgmgr" on both nodes. Say, the new disk is hdisk11.
Create the mirror: Notice that i postpone the syncing because this way i can sync several VGs at once and i can parallelize the syncing (see "-L" switch to "syncvg").

vgconvert
VGCONVERT(8) System Manager's Manual VGCONVERT(8)NAME
vgconvert - convert volume group metadata format
SYNOPSIS
vgconvert [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--labelsector] [-M|--metadatatypetype] [--pvmetadatacopies#copies] [--meta-
datasizesize] [--version] VolumeGroupName [VolumeGroupName...]
DESCRIPTION
vgconvert converts VolumeGroupName metadata from one format to another provided that the metadata fits into the same space.
OPTIONS
See lvm(8) and pvcreate(8) for options.
EXAMPLE
Convert volume group vg1 from LVM1 metadata format to the new LVM2 metadata format.
vgconvert -M2 vg1
RECOVERY
Use pvscan(8) to see which PVs lost their metadata. Run pvcreate(8) with the --uuid and --restorefile options on each such PV to reformat
it as it was, using the archive file that vgconvert(8) created at the start of the procedure. Finally run vgcfgrestore(8) with that ar-
chive file to restore the original metadata.
