Nope. None at all.

I am planning on bringing down all volume groups, exporting them and removing all powerpath and SAN hdisk device and then running cfgmgr and powermt config and see if that resolves this. I'll post results

THis has been done teice. The second time we even removed the FC drivers and rediscovered everything and for some reason, the system is still referencing the old SAN. EMC and I have no idea where the system is still findin the reference to the old SAN.

After the reboot the old hdiskpower drives come back and show the WW name for the old SAN. Bizarre.

Anywho. Is anyone aware of a script that will allow me to import the volume groups on a reboot that I can incorporate into the inittab?

I rekon I would need one that inititally knows the correct PVID and verifies that before the import.

Thanks for all the help and suggestions.

Mike

I suspect you need to correct the disk config and then run savebase.
The old definitions are probably still in the boot ODM and are being copied into the runtime ODM each boot.
