3. Creating an HDLM Environment
149
• To the slices of a single LU, allocate the Solaris file system, swap device,
dump device, Sun Cluster global device file system, and replica of the SDS
or SVM state database.
• To the slices of multiple LUs, allocate the Solaris file system, swap device,
dump device, Sun Cluster global device file system, and replica of the SDS
or SVM state database.
In this case, make sure that the physical path of each LU is the same.
2.
Get Solaris to recognize the LUs to be used by the post-migration boot disk.
3.
Set the LU slices to be used by the post-migration boot disk.
4.
Complete the preparations for installing HDLM in the pre-migration environment
and then install HDLM, referring to the description in 3.5 Installing HDLM.
Perform the necessary steps.
Note
Note the following when you set the devices to be excluded at step 11 of
3.5.3 Performing a New Installation of HDLM (When Sun Cluster Is Not
Being Used) or in step 17 of 3.5.4 Performing a New Installation of HDLM
(When Sun Cluster Is Being Used):
- If the boot disk in the pre-migration environment is an HDLM-managed
device, change the setting to exclude it from HDLM management.
- Set the post-migration boot disk as an HDLM-managed device.
After you finish these steps, perform the procedure described in (5) Setting Up the
Post-Migration Environment.
(4) Migration by Building a New Pre-Migration Environment
Perform the following steps in the pre-migration environment. The workflow is shown
in Figure 3-11: Flow of setting up the boot disk environment when building a new
pre-migration environment.
