Restoring a client to dissimilar disks
Table: To perform a dissimilar disk restore is an overview of the process to restore to dissimilar disks. If you did not prepare a restore configuration in advance, BMR automatically creates an editable restore configuration during this process.
Note the following for UNIX and Linux DDR:
Unused VxVM disks on Solaris clients are marked restricted and should remain restricted.
You cannot map Linux LVM volume groups with the physical volumes that were created on top of multi devices with the same configuration. The physical volumes are mapped to either disks or partitions but not to a multi device.
Table: To perform a dissimilar disk restore
Step | Task | Procedure |
|---|---|---|
Step 1 | Prepare to restore the client. | If you prepared a restore configuration in advance, select that configuration during the prepare operation. |
Step 2 | Begin the restore by booting the client using either network boot or media boot. |
If you use a configuration where the protected system's volume configuration is already mapped to the new disks, the restore proceeds as a standard restore. No intervention is required. If BMR detects that the disks are different and are not already mapped, BMR enters DDR mode. In case of Windows, you can map volumes to recovery time disks at this point by using auto popped-up BMR configuration mapping GUI. See BMR restore process. |
Step 3 | Save the editable restore configuration. | Non-editable configuration only. If you use a configuration that cannot be edited, BMR creates an editable restore configuration. It copies the current configuration and prompts you to enter a name for it, as follows: Current configuration name for restore is 'current'. Please enter the name for a new editable configuration: |
Step 4 | Save the discovered configuration. | To obtain the layouts of the new disks, BMR discovers the hardware of the client. BMR prompts you for a name for the discovered configuration, as follows: Please enter the name for a new discovered configuration: BMR saves the discovered configuration. Later, you import the disk layouts from this discovered configuration into the restore configuration by using option on BMR configuration mapping GUI (as described in step-6). |
Step 5 | Open the Change Configuration dialog box . | After the discovered configuration is saved, in the NetBackup Administration Console on the master server, open the Change Configuration dialog box for the restore configuration. |
Step 6 | Initialize the restore configuration. | Initialize the restore configuration with the new disk layout from the discovered configuration. And then map the original volume configuration to the new disks. |
Step 7 | Prepare to restore and then restore the client, using the edited restore configuration. | See Preparing a client for restore. |
Step 8 | If the disk mapping in the restore configuration is incomplete, BMR enters DDR mode again so you can continue to map volumes to disks. |
