cannot label 'c0t5000CCA0251EF65Cd0': EFI labeled devices are not supported on root pools
I'm running Solaris 10 u9. I just applied the April quarterly patch cluster. I'm trying to mirror the boot disk which is using zfs, something I've done before w/o problems prior to the patch cluster install.



Code:
disk=c0t5000CCA0251D9514d0;mirrordisk=c0t5000CCA0251EF65Cd0;echo $disk $mirrordisk
  c0t5000CCA0251D9514d0 c0t5000CCA0251EF65Cd0
   
  prtvtoc /dev/dsk/${disk}s2 > /tmp/disk-partitionTbl
  fmthard -s /tmp/disk-partitionTbl /dev/rdsk/${mirrordisk}s2
  fmthard:  New volume table of contents now in place.
   
  zpool attach -f rpool $disk $mirrordisk
  cannot label 'c0t5000CCA0251EF65Cd0': EFI labeled devices are not supported on root pools.

  A disk that is intended for a ZFS root pool must be created with an SMI label, not an EFI label. 
  You can relabel a disk with an SMI label by using the format -e command.
   
  format -e c0t5000CCA0251EF65Cd0
  selecting c0t5000CCA0251EF65Cd0: solaris
  [disk formatted]
   
   
  FORMAT MENU:
          disk       - select a disk
          type       - select (define) a disk type
          partition  - select (define) a partition table
          current    - describe the current disk
          format     - format and analyze the disk
          repair     - repair a defective sector
          label      - write label to the disk
          analyze    - surface analysis
          defect     - defect list management
          backup     - search for backup labels
          verify     - read and display labels
          save       - save new disk/partition definitions

  It looks the same.

Can you post zpool status rpool?

Old 06-04-2012
Code:
zpool status rpool
  pool: rpool
 state: ONLINE
 scan: none requested
config:

          c0t5000CCA0251D9514d0s0  ONLINE       0     0     0

errors: No known data errors

Try:
Code:
zpool attach -f rpool c0t5000CCA0251D9514d0s0 c0t5000CCA0251EF65Cd0s0

# 5  
Old 06-04-2012

try to "destroy" the disk label with dd... something like
Code:
dd if=/dev/zero of=$HARDDRIVE count=16

after that try to relabel the disk with format -e and run the zpool attach command again...

@TKD, you are using the wrong device name (without slice 0).

As bartus11 already suggested, use c0t5000CCA0251D9514d0s0
