Am new to SAN's so any help would be appreciated. I have 2x HP server connected via duel SAS cables to a HP P2000 SAN with Duel controllers. I have provisioned a VDISk and shared storage on the SAN and can see this on the server. However when I remove on of the cables to the SAN the drive disappears. How do I set the SAN to be a shared storage location accross all of the 4x Cables to the 2 servers. Do i need to set the servers into a failover clustered enviroment to achive this?
