    We are on a windows 2008 x64 and SQL 2008 x64. Our cluster is a 2-node active passive one. We need to replace our existing SAN with a new one and would like to keep using the existing nodes for it.
    Has anyone have any experience or idea of what to do? I need some detail steps because I will need to do it on a live system and no testing resource I can use to test this move.

    For that project , it could have 2 applicable solutions :

    1. Either to use purely SAN based techniques to replicate the concerned SAN LUNS with the same configurations + data + disks signature + disks no ( This is already applicable through Enterprise SANs like EMC…etc)

    2. Or to use SAN + DB techniques tighter by:

    · Replicating the concerned SAN LUNS with the same configurations + data but with different + disk signature + disks no then you could rebuild another cluster on the new SAN LUNs…

    · Then restoring MSDB from old cluster to preserve all old jobs

    · Then attaching the same DBs on the new clusters.

    · But assure the same logins with their DB users are exists there by the same privileges
