ACTION PLAN

====================================================

Please check correct physical path from OS output for root and root mirror

reset-all

probe-scsi-all (try boot now, if not worked, please use below mention reference steps)

====================================================

Please unencapsulated the root disk as per below procedure

How to unencapsulate from SVM

1. boot -F failsafe or boot cdrom -s

this should automatically prompt to execute fsck /

and will automatically prompt to mount rootfs /a

Otherwise, ‘boot cdrom -s’, run format and confirm which

controller/target number relates to hardware path.

# format

## Note – when booted from cdrom or failsafe don’t assume the bootdisks controller/target

number is the same as before.

Always confirm the hardware path from format to ensure you fsck the correct disk.

The device trees can differ when booted cdrom to how they are when booted from your normal

boot disk.

2. fsck on your primary boot disk

example# fsck /dev/rdsk/c0t0d0s0

3. mount the boot disk upon the successful completion of fsck.

ex: # mount /dev/dsk/c0t0d0s0 /a

4.i) cp /a/kernel/drv/md.conf /kernel/drv/

ii)

Update the md driver

# update_drv -f md

devfsadm: mkdir failed for /dev 0x1ed: Read-only file system (don’t worry about this message)

5.Collect the following outputs

#metastat -p

#metastat -c

#metadb -i

6. Edit the /etc/system file, and remove the “rootdev” line shown below:

# vi /a/etc/system

*rootdev:/pseudo/md@0:0,0,blk

Do not comment-out this line – REMOVE IT!

7. In the /etc/vfstab file, replace the lines for the system file system

metadevices with their underlying partitions.

For example, change lines from:

/dev/md/dsk/d0 /dev/md/rdsk/d0 / ufs 1 no –

to:

/dev/dsk/c0t0d0s0 /dev/rdsk/c0t0d0s0 / ufs 1 no –

ONLY change the lines for root (/) ,/var,/opt, /usr and swap and commentout all other file system entries.

8. Clear the metadevices for root (/) ,/var,/opt, /usr and swap

ex: # metaclear -f -r d0 d1 d2

9. clear the metadatbases

Ex: # metadb [-f] -d c0t0d0s7

10. Install the bootblk

ex: installboot /a/usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0

11. update the boot archive

bootadm update-archive -fvR /a (must use -f option, it will forcedly update boot archive)

12. init 0

13.ok> boot devalias of primary disk

14)Then remirror rootfs using standard SVM procedures.
