I can see the new LUN when running fdisk:
so I think the new LUN is /dev/sda
I don't think this is the same LUN because otherwise you would see the filesystems/partitions/whatever on it. Notice that LUNs have an identifier (the so-called "WWN" and you can identify it by this. Use your HBAs driver software to find out the WWNs of your attached disks.
Notice also that there is the "zoning" which has to be correct: basically zoning is somewhat analogous to firewall rules: each partner (the LUN, the HBA, the fabrics port) has an identifying WWPN (World Wide Port Number) and you create a rule that says WWPN A (your adapter) is allowed to connect to WWPN B (the LUN) and vice versa. If the LUN was part of a different system before you perhaps need to change this rule to make it visible to the new system (or, more precisely, to its FC adapter). Your storage administrator should be able to explain the intrinsics to you in more detail.
