3. Creating an HDLM Environment

160

Perform steps 1 to 16 in the pre-migration environment.

2.

Allocate the LUs to be used by the boot disk in the post-migration environment.

3.

Get Solaris to recognize the LUs to be used by the post-migration boot disk.

4.

Set the LU slices to be used by the post-migration boot disk.

If using Sun Cluster, go to the next step.
If not using Sun Cluster, go to step 8.

5.

Assign device IDs.
The following shows an example of executing the command:


# /usr/cluster/bin/scdidadm -r

6.

Notify the server of the new device ID information.
The following shows an example of executing the command:


# /usr/cluster/bin/scdidadm -ui

7.

Update the Sun Cluster global device namespace.
The following shows an example of executing the command:


# /usr/cluster/bin/scgdevs

8.

If the post-migration boot disk is an HDLM-managed device, exclude it from

HDLM management by executing the procedure described in 3.5.5 Using the

HDLM Device Unconfiguration Function When Performing a New Installation of

HDLM.

9.

Set the boot block for the post-migration environment, specifying the

post-migration slice 0 (

/

(

root

) file system).

The following shows an example of executing the command:


# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /
dev/rdsk/c0t0d0s0

10. Initialize the Solaris file system in the post-migration environment. If using Sun
