Where is the PVID stored
Quick background on all this before the real question is asked.
A couple of weeks back I configured an HACMP cluster between to servers with SAN based shared storage. Now that the cluster is up and functional with no problems an issue with the EMC frame comes up. The only fix for the problem, according to the SAN guys, is to move everything over to a new frame.
My concern with moving the disks to a new frame is regarding the PVIDs. If those change then HACMP will have to reconfigured, if they don't change then there is very little for me to do other than to shutdown the cluster and reboot the servers.
So, the big question(s) is/are:
Where is the PVID stored?
Will this break HACMP?
