Hi all I have a job to do this Saturday which involves upgrading the hard drives in a Compaq Proliant 1600 NT4 Server (SP6a). At present it has a hardware raid0 mirror consisting of 2x 18.2 GB SCSI disks. There is very little free space on the system - hence the need for an upgrade. My intention is to leave the mirror in place, install a 3rd drive into the system (36GB) and clone the original volumes onto this new drive using Acronis True image Server 8. Then I'll physically remove the original drives and leave the newly cloned disk in their place. When i get my hands on another 36GB scsi drive (should be a few days) I can regenerate the mirror set. Can anybody see any reason why this wouldn't work? Thanks in advance Paul.
