Increasing size of a RAID-1 Volume

[Douglas]

We have Win2K Server with two hard drives, 18GB SCSI, in a CPQ proliant with
Smart Array and RAID-1. We need more space. Can I break the mirror by
removing one drive, then insert a 72GB drive, let the system rebuild the
array, then break the array again by removing the last 18GB drive and
inserting a second 72GB? Will windows detect the size change? Has anyone
heard of doing this? Is there a better way?

Thanks!
Douglas

You would probably want to ask HP if this a supported option with their
RAID controllers. If it is, you could use diskpart.exe, to extend a data
volume after changing both disks, see this MS Knowledge Base article:

The other option is to backup, recreate and restore.
