Adaptec HostRaid onboard - need to change disks in Raid-1

[damjanster]

I need to replace the disks that are configured in raid1 on a hostraid adapter. The new disks are twice as big, one of the old disks is making problems. I need to migrate the Windows 2000 server onto the new disks and configure them as raid1.

How can I do this without reinstalling the OS.

To migrate the system to the new harddisks is the best way to create a image of the system, make the raid new with the new harddisks and restore the image.
So after the restoration you might see some "unalocated" space on your hard drive - if your restoration procedure does not resize the partitions to match the disk already.
