    Break RAID1 without losing data on T3-1 server

      Hi everyone,

      With raidctl it was possible to remove a RAID1 volume but still be able to boot from 1 of the 2 disks. I now tried the same thing on a T3-1, I went into the OK prompt and did a delete-volume. When I now try to boot from either one of the disks I get this:

      {0} ok boot disk0

      SPARC T3-1, No Keyboard
      Copyright (c) 1998, 2011, Oracle and/or its affiliates. All rights reserved.
      OpenBoot 4.32.4, 15872 MB memory available, Serial #97699876.
      Ethernet address 0:21:28:d2:c8:24, Host ID: 85d2c824.

      Boot device: /pci@400/pci@1/pci@0/pci@4/scsi@0/disk@p0 File and args:
      Bad magic number in disk label
      Can't open disk label package
      ERROR: boot-read fail


      Can't open boot device

      Is there a way I can still fix this, or will I have to reinstall Solaris 10 from scratch.

          Docs (http://docs.oracle.com/cd/E19836-01/E21415/E21415.pdf ) say:
          Caution – When you create a RAID volume using the on-board disk controllers, all
          data currently on the disks you include in the volume will be lost.

          But you can try boot from CD ( or net), restore label and partition on disk, check that data available and reinstall boot block.
