Disk Issue

[HMUSER]

We are setting up our new SAN box and this is the first for the company.

I have setup my 2 boxes and my volumes on the SAN cluster.

I then initialized the disks and formatted the drives on my server however when I rebooted the server and SAN cluster my drives now are all not initialized and need to be formatted causing me to loose the data on the drives?

Is there a way of getting the drives to appear as they were on my Server or is this because the way I have rebooted both the SAN and server?
