OCR/Votting disk change location

Hi,

I need to move my 2 nodes RAC (Solaris 10 / Oracle 10g (10.2.0.3)) to a new data center.

My OCR and Votting disks are on a SAN (x) and on the new datacenter I want to put them on a new SAN (y).

How can I perform this server movement without losing the current RAC/Clusterware configuration?

I was planning to do the following:

- Backup current databases
- Backup spfile
- Backup Diskgroups/ASM configuration
- Delete databases
- Delete Diskgroups/ASM
- Shutdown CRS (crsctl stop crs)
- Backup OCR disks (ocrconfig -export export_filename)
- Backup Votting disks (dd if=voting_disk_name of=backup_file_name)
- Turn off the servers
- Move them to the new Datacenter
- Attch the new SAN
- Restore Votting disks (dd if=backup_file_name of=voting_disk_name)
- Restore OCR disks ( ocrconfig -import export_filename)
- Then recreate Diskgroups/ASM
- Restore databases


Is this the right procedure/commands to accomplish it without losing the RAC configuration?

I am trying to avoid rebuilding the whole RAC from scratch.

Thanks,
AShum
