I have a 2 node GPFS cluster setup on AIX (using VIO clients with 7.1).
Installed Oracle RAC (with GPFS), and taken LUN snapshots.
I want to present/restore these luns to another gpfs cluster and restore the exact application setup.
Is there any command or procedure to restore the gpfs on to the new cluster (similar to importvg ..).
NOTE: the luns are exported to the host.
I tried the following:
() mmnsddiscover and mmdevdiscover but did not help.
() mmexportfs (its expects the FS to be unmounted on all nodes)
which is not helpful.
() mmbackupconfig (expects all the nodes to be up) again not
I'm looking for a way to backup the config and restore on another cluster.
Any inputs are highly appreciated.

The commands you're going to be looking at are:
a. mmfsctl <gpfsdev> suspend # to flush all cache to disk for a consistent on-disk copy
b. mmfsctl <gpfsdev> resume # to resume I/O to the file system
b. mmfsctl <gpfsdev> syncFSconfig # to copy the file system definition to the remote GPFS cluster
