I have an oes2 sp4 6 node cluster. I am trying to expand our data2 pool ( a clustered resource). I have allocated the space on the San all the nodes can see the new space after recanning the scsi bus and using EMC powerpath. I used evmsgui to initialise the new space on one of the nodes with no problem. when I try to expand the pool using nssmu it just waits at the blue screen and doesn't return any devices, pools, etc. I have to end up closing the session and killing the process. even in imanager it doesn't populate any of the devices or pools etc.
any suggestions to resolve a critical space issue for 4000 users ???? would be much appreciated.
