zfs discuss - Jul 2008 - zfs sparc boot "Bad magic number in disk label"

Hello,

I recently installed SunOS 5.11 snv_91 onto a Ultra 60 UPA/PCI with OpenBoot
3.31 and two 300GB SCSI disks. The root file system is UFS on c0t0d0s0.
Following the steps in ZFS Admin I have attempted to convert root to ZFS
utilizing c0t1d0s0. However, upon "init 6" I am always presented with:

Bad magic number in disk label
can''t open disk label package

My Steps:

1) format 1 -> Partition -> Modify -> Free hog -> All available to
slice 0 -> label > quit
2) zpool create pool c0t1d0s0
3) lucreate -c c0t0d0s0 -n sol11 -p pool

Result:
  Analyzing system configuration.
  Comparing source boot environment <c0t0d0s0> file systems with the file 
  system(s) you specified for the new boot environment. Determining which 
  file systems should be in the new boot environment.
  Updating boot environment description database on all BEs.
  Updating system configuration files.
  The device </dev/dsk/c0t1d0s0> is not a root device for any boot
environment; cannot get BE ID.
  Creating configuration for boot environment <sol11>.
  Source boot environment is <c0t0d0s0>.
  Creating boot environment <sol11>.
  Creating file systems on boot environment <sol11>.
  Creating <zfs> file system for </> in zone <global> on
<pool/ROOT/sol11>.
  Populating file systems on boot environment <sol11>.
  Checking selection integrity.
  Integrity check OK.
  Populating contents of mount point </>.
  Copying.
  Creating shared file system mount points.
  Creating compare databases for boot environment <sol11>.
  Creating compare database for file system </>.
  Updating compare databases on boot environment <sol11>.
  Making boot environment <sol11> bootable.
  Creating boot_archive for /.alt.tmp.b-b2.mnt
  updating /.alt.tmp.b-b2.mnt/platform/sun4u/boot_archive
  Population of boot environment <sol11> successful.
  Creation of boot environment <sol11> successful.

4) luactivate sol11
5) lustatus
  
Result:
  Boot Environment           Is       Active Active    Can    Copy      
  Name                       Complete Now    On Reboot Delete Status    
  -------------------------- -------- ------ --------- ------ ----------
  c0t0d0s0                   yes      yes    no        no     -         
  sol11                         yes      no     yes       no     -         

6) eeprom | grep boot-device

Result:
  boot-device=/pci at 1f,4000/scsi at 3/disk at 1,0:a /pci at 1f,4000/scsi at
3/disk at 0,0:a

7) init 6

Any advice in this matter would be appreciated. Thank you.

Hi Joe,

It is possible that your c0t1d0s0 disk has an existing EFI label instead
of a VTOC label?

(You can tell by using format-->disk-->partition and see
if the cylinder info is displayed. If no cylinder info, then an EFI
label.)

Relabel with a VTOC label, like this:

# format -e
select disk
format> label
[0] SMI Label
[1] EFI Label
Specify Label type[1]: 0
Warning: This disk has an EFI label. Changing to SMI label will
erase all current partitions.
Continue? yes

The entire process would look like this:

1. Destroy the existing pool.
2. Relabel the disk.
3. Recreate the pool.
4. Restart the LU migration.

Please let me know if this is the case. I''ve run so many LU
migrations recently that I can''t remember if this is EFI scenario
or not.

Hello Cindy,

That did the trick. Thank you for your quick assessment and solution.
