Mirror a SCSI drive with NT 4.0

Anyone have any notes or sights telling me how to mirror a 18 GB SCSI drive using the feature in NT 4.0?

Mirroring is pretty straightforward. All you need is NT server and 2 hard drives. In the disk administrator, highlight the primary drive and the empty drive. From the pull down menus select create mirror set. It will take a while to become "healthy" during which time you will see constant drive activity. By a while i mean it could be hours. David Moore

I tried highlighting both then using the drop down menu, but the option is jut blocked out. I have already formated the other drive with NTFS also.

The second drive needs to be completely unformatted - no file system, no partitions, no nothing. NT will create everything as an exact duplicate of the primary disk.

Highlight the primary disk, hold the Ctrl key and highlight the second, select "Fault Tolerance" and "Establish Mirror" (verbage may be different). NT will do the rest and yes, it does take a while. Your system will still be available during the mirroring process, but will be real sluggish...

if this is a production box I'd strongly suggest using hardware for any RAID level (0, 1 or especially 5) instead of disk administrator.

just my 2c

You are probably selecting drives of different sizes of 2 drives that already have data on them.

Take a volume that is smaller or the same size as an empty amount of space on a physically different disk and follow what Voyager1 said.
