    T2000 does not reboot because of wrong RAID configuration

    scampsd
      Good afternoon,
      On a T2000 I have a strange situation: the /etc/vfstab file mentions disk targets 0 and 2 while the RAID controller mentions disk targets 1 and 2. This seems to cause the machine not to boot.
      /etc/vfstab:
      # cat vfstab
      #device                            device       mount     FS      fsck    mount     mount
      #to mount                          to fsck      point     type    pass    at boot   options
      #                                  
      fd                                       -      /dev/fd     fd       -         no   -
      /proc                                    -      /proc     proc       -         no   -
      /dev/dsk/c0t0d0s1                        -      -         swap       -         no   -
      /dev/dsk/c0t0d0s0       /dev/rdsk/c0t0d0s0      /          ufs       1         no   -,logging,noatime
      /dev/dsk/c0t0d0s3       /dev/rdsk/c0t0d0s3      /dir1      ufs       1         no   -,logging,noatime
      /dev/dsk/c0t2d0s6       /dev/rdsk/c0t2d0s6      /dir2      ufs       2        yes   logging,noatime
      /dev/dsk/c0t2d0s4       /dev/rdsk/c0t2d0s4      /dir3      ufs       2        yes   logging,noatime
      /dev/dsk/c0t2d0s5       /dev/rdsk/c0t2d0s5      /dir4      ufs       2        yes   logging,noatime
      /dev/dsk/c0t0d0s5       /dev/rdsk/c0t0d0s5      /dir5      ufs       2        yes   -,logging,noatime
      /dev/dsk/c0t0d0s6       /dev/rdsk/c0t0d0s6      /dir6      ufs       2        yes   -,logging,noatime
      ...
      => Targets 0 and 2 are to be used.

      At boot-prompt:
      {0} ok probe-scsi-all
      /pci@780/pci@0/pci@9/scsi@0
      
      MPT Version 1.05, Firmware Version 1.09.00.00
      
      Target 1 Volume 1
      Unit 0   Disk     LSILOGICLogical Volume  3000    143112591 Blocks, 73 GB
      Target 2 Volume 0
      Unit 0   Disk     LSILOGICLogical Volume  3000    143112591 Blocks, 73 GB
      => Here the targets 1 and 2 are defined. Most probably this mismatch causes the machine not to boot.

      As the machine can be formatted, I am wondering how to do this (I have no experience working with RAID controllers). Does anybody know how to remove target 1 from the "show-volumes" and how to create target 0?

      Thanks
      Dominique
