NetVault Bare Metal Recovery 11.0 - User Guide for Plug-ins

In some instances of using the Windows® PE-based Plug-in Offline Client, the logical unit numbers (LUNs) of a Fibre Channel card are identified as drives by the Windows Disk Manager. As a result, NetVault Backup might also interpret the LUNs as drives, display them on the NetVault Backup Selections page, and attempt to include them in a backup job if they are selected. The VSS Backup job then fails because of this issue. To work around this issue, you can edit the “nvdrw.cfg” file to prevent the LUNs from appear on the NetVault Backup Selections page.

To update the file, perform the following steps.

Locate and open the “nvdrw.cfg” file in a text editor.

For the Plug-in Offline Client, this file is located in \\Windows\System32\. For the Plug-in Live Client, this file is located in \\NetVault Backup\config\. If the file does not exist, you can create it.

Update the file to include a section similar to the following; replace the applicable segments with the information for your card:

[Disk Vendor:Product]

IgnoreDisk=LSI, Universal Xport

Save and close the file.

For the Plug-in Offline Client, complete the following steps to restart the drdaemon:

On the NetVault Bare Metal Recovery Client, start the Windows Task Manager by typing the following at a command prompt, and pressing Enter:

taskmgr

In the Windows Task Manager screen, select the Processes tab, right-click drdaemon, select End Process, and close the Task Manager.

To restart the drdaemon, type the following at a command prompt; if necessary, click Launch CMD again; and press Enter:

drdaemon

For the Plug-in Live Client, access the Windows Task Manager on the NetVault Bare Metal Recovery Client, select the Processes tab, right-click nvdrw, select End Process, and close the Task Manager.

Access the NetVault Backup Selections page of the NetVault Backup Backup window, and verify that the changes are reflected.

Performing a restore in which Disk Numbers are different from the backup

In some instances, the Disk Number assigned to a drive during backup might be different for the restore. To work around this issue, note the Disk ID and disk order displayed on the Create Selection Set page, use the Plug-in Offline Client to boot the machine that is targeted for the restore, and then note whether the disk order is different. If the order is different, use the Rename option during the restore process to prevent data loss.

To determine whether the disk order is different, perform the following steps.

In the Navigation pane of the NetVault Backup WebUI on the NetVault Backup Server, click Create Restore Job.

On the Create Restore Job — Choose Saveset page, select Plug-in Server from the Plugin Type list.

In the saveset table, double-click the applicable saveset to open it.

When the backed-up client machine appears, double-click it to open it and list the disks that were backed up.

Note the information displayed within the parentheses for each disk.

Use the Plug-in Offline Client to boot the NetVault Bare Metal Recovery Client that is targeted by the restore, access the NetVault Backup Server, and open the NetVault Backup Selections page.

Drill down to the disk-level of the client, and note the current disk order.

If the order is different, use the Rename option during the restore.
