The following is an example when the post-replacement HDLM device is

c6t50060E8010027A80d8s0:

# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk

/dev/rdsk/c6t50060E8010027A80d8s0

5. Execute the eeprom command to specify the post-replacement device as

the boot device.

# eeprom boot-device=/pci@7c0/pci@0/pci@1/pci@0,2/SUNW,qlc@2,1/

fp@0,0/disk@w50060e8010027a80,8:a

For how to set a boot device name, see step 11 in Setting Up the Post-

Migration Environment on page 3-91 of Procedure for Configuring a Boot

Disk Environment on page 3-83.

For how to obtain a device name to be set for OBP, see the

documentation of the HBA you are using.

6. Execute the init command to restart the host.

# init 6

Do not use the reboot command to restart the host.

Performing a Check after Restart

After the host restarts, perform the following check:

1. Execute the df command to make sure the file system is mounted.

# df

/ (hdlmpool/ROOT/hdlmboot):124234885

blocks 124234885 files

/var (hdlmpool/ROOT/hdlmboot/var):

124234885 blocks 124234885 files

/export (hdlmpool/export ):124234885 blocks

124234885 files

/export/home (hdlmpool/export/home):124234885

blocks 124234885 files

/hdlmpool (hdlmpool ):124234885 blocks

124234885 files

Make sure the / (root) directory, the /var directory, the /export

directory, and the /export/home directory are mounted in the root pool

(hdlmpool) after the migration.

2. Execute the dumpadm command to make sure the dump device is migrated

to the root pool (hdlmpool) after the migration.

Make sure /dev/zvol/dsk/hdlmpool/dump is valid.

3. Perform the view -path HDLM command to check the path status after

the migration.

If the ZFS boot disk environment after the migration is a device which is

not managed by HDLM, this procedure is not necessary.
