homeyjoe is right. You'll need to update the zoning on your SAN switches. You will also need to update the SAN device, and it's wwpn mappings. Each LUN is "mapped" to particular fiber adapter addresses called wwpn's (world wide port name). SAN switches have zones which are part of zonesets. At it's simplest, zones specify which fiber adapters can communicate. zones are grouped together in zonesets.
You can determine what the wwpn of the new fiber card is using
Code:
lscfg -vpl fcs1 | grep Network
