PLEASE HELP
 You manage a Windows 2003 computer named Trade1 that functions as a file
server. The data volume on Trade1 is mirrored. Each physical disk is on a separate
controller.
One of the hard disks that contain the data volume fails. You discover that the
failure was caused by a faulty SCSI controller. You replace the SCSI controller.
You need to restore the data volume to its previous state on immediate basis?
A. Run the diskpart active command on the failed volume
B. Convert both disks to basic disks, and then restore the data
C. Break the mirror, and then re-create the mirror
D. Select a disk in the mirror, and then reactivate the volume

SCSI controller is compatible with each SCSI drive, so answer D is correct "Select a disk in the mirror, and then reactivate the volume"

This is a software RAID-1 and using Disk Management snap-in console you can fix it according to D answer. SCSI controller must be compatible with server and requires appropriate drivers for it.

Krzysztof

@KCTS: yup, looks like 290 exam :] In a question is a statement that SCSI controller cause that, not disk :) So after SCSI controller was replaced by new one, just only reactivate volume :) You don't have to break mirror and recreate it (IMHO)

Is Your AD Toolbox Looking More Like a Toybox?

My thoughts were that the the controller had failed then the disk on that controller is likley to be corrupt - so the suspect disk needs to be zapped and the data re-mirrored from the 'good' disk'
