    How to unmirror a NW 5.1 Volume

    Locked

    by jf555 · about 19 years, 7 months ago

    Hello,

    I used to have a procedure whereby I could unmirror a NW 5.1 volume by starting with Server -na -ns, loadstage 0, 1, 2(?) and then eventually load nwconfig from where then I could break the mirror. Disk 0 is defective, however, Disk 1 is OK so that I have to use it as the primary then install a good disk for secondary. I would appreciate if you could complete and correct the forgotten procedure, Thanks

      I had to do this once a long time ago, with a disk that was intermittently failing. As I recall, it was fairly straight forward:

      DOWN the server to a DOS prompt.

      If the boot partition is on the defective disk (disk0), be sure to create a partition on disk1, make it bootable, and copy the DOS partition contents from DISK0 to DISK1

      Swap the ID’s of the disks.

      Boot the server with -na -ns. (this confirms that the “good” disk is bootable)

      Manually load the driver for the disk controller(s)

      Mount SYS

      Use NWCONFIG / Disk options / mirroring. highlight the defective drive, press DEL.

      Once you’ve replaced the drive, just re-create the mirror set.

      If you know which drive is failed, why don’t you just unplug and or replace it? This is the safest thing to do.

      That’s the smart thing to do, as Novell will automatically mount any disk mirror that it can read.

      You can type ABORT REMIRROR PARTITION and it will abort mirroring until you reboot or tell it to continue to remirror.
