I have a ibm xseries 346 with a disk expansion unit, exp 400 disk array.
The server has 2 disks set up as raid 1, these run the os. This server currently runs exchange
The disk unit has 11 disks including a hot swap.
We have an onboard scsi controller and a 6m server raid card.
We moved offices yesterday and a idiot IT guy disconnected the scsi cable connected the disk array from the server with out making a note of which channel or card the unit was connected too. I now have to connect everything up but have no idea which controller was used, and I can not afford to lose the data on the disks as an exchange restore would be a complete nightmare. What do you think the best way would be to work out which channel the disk unit should be connected too
