This forum is specific to Dell PS Series Storage (Equallogic)
However, with all SAN storage, you want to first shutdown the servers, then shutdown the storage
I would check in the GUI, for a shutdown option. That's preferred to just powering off the SAN. If you are going to do that. Wait 5 minutes after shutting down all the hosts before pulling power. This should insure that all data in cache is written to the RAID.
