Moving disk units

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

A long long time ago.... I posted a question about moving disks around
between cabinets.

The good news is that it works!  We followed these steps to a
successfull move:

save the entire system.
save the entire system.
end RAID on all units being moved or re-moved (This is why we saved
entire system twice!)
removed 8 2G units from the system ASP  (1.5 hours)
moved 8 4G units from 720 cabinet to the 5052 top hat where the 2G
drives were (1 hour)
added 8 8.5G units into the 720 cabinet (10 minutes)
started RAID on all disk units moved or added (1.5 hours)
added the 8G units to the system ASP (2 minutes)

The system happily found the moved 4G drives in their new homes. We
didn't try but are quite certain that moving the drives with RAID still
enabled would have been a problem as the controller is what handles that
and they moved to a different controller.
