RAID 1 – How to upgrade disks

Hi there, I'm currently running a Windows Server 2003 (web edition) box which runs 2 8GB U320 SCSI disks, which make up a RAID 1 array. On this array, is a C: and D: logical drive, C being my OS and applications, D being my data. I've just purchased 2 148GB drives, which I now want to swap in to upgrade the array. I've installed the first 148GB drive, and broken the mirror on the original 2 drives. I have created a mirror on the new 148GB drive, and it's all running fine at this point. My question is, how do I now remove the remaining (primary) 8GB drive, and sub in another 148GB drive? I'm assuming I'll have some boot problems if I do this, so I'm stuck at the moment.. Any thoughts?

Thanks. We'll let you know when a new response is added.

Couldn’t you use ghost or some other imaging software to make an image of the current system and then swap out the drives and put the image back?

    You edit your boot.ini and point it to the new partition, install the next 148gb drive and setup your raid. When it has completed the initialization and built the image on the newest drive you can go back and edit your boot.ini to point back to the original partition. Voiala!

    Some additional questions: How was the RAID 1 established: Software (via the O/S) or Hardware (via a dedicated RAID controller? If software RAID, you best bet would be to boot into Ghost/Drive Image Pro/Altiris/whatever you have available and image the 8GB partition onto the 148GB partition. If you have a dedicated controller, the controller probably came with (or has available) software which will facilitate the transfer. There are other possibilities, of course, but those are the easiest...
