I have a NT 4.0 Terminal Server running software mirroring with 2 Hot swap compaq SCSI drives on a compaq 1600.. I got an error this morning "System Error- FT Orphaning- A disk that is part of a fault tolerant volume can no longer be accessed." Under Disk Administrator I can not see my DISK 0. It says OFF-LINE under that. Could anyone help me with some good pointers on how to repair my mirrored volume?? HELP !!!!

Your disk 0 has failed and needs to be replaced. Make a NT boot disk that has the Boot.ini, Ntdetect.com, NTLDR on it. Configure the Boot.ini to point to the disk and partision that is working. Its possible that your Boot.ini is already pointed to the correct partisioin since it booted. Replace the disk, then in disk admin break the mirror, and recreat the mirror. Specific help for breaking and creating the mirror can be found on MS web site. If your Proliant 1600 has an Array controller then it is my recomendation that you use the hardware (Array controller) to create the mirror. Unfortunately I do not think this can be done without starting over on the server build.

Here's something about the Boot.ini incase you need.
