How do I configure Legato's NetWorker for Mirapoint NDMP selective restore from an image?

Solution

 

Note: Before reading this article, Mirapoint highly recommends reading the latest version of the Mirapoint Backup and Restore Guide.

This document describes how to modify your existing Legato NetWorker (version 7.1) DMA configuration and Mirapoint NDMP backup setup to allow for selective restore from an image.

If you are running NetWorker version 7.1.2 on a Solaris workstation, install the 64-bit package. Legato's 32-bit version does not operate correctly when working with NDMP file histories. Versions other than the 64-bit package can "hang" when attempting to do a recovery. If you are running NetWorker's 32-bit package you need Legato's patch, or you have to uninstall it and install the 64-bit package.

Legato's Windows 2000 version also fails without their patch. Contact Legato directly for more information on running either the Solaris 32 bit package or the Windows 2000 version.

Your Mirapoint appliance must be equipped with 3.6 or higher operating system.

This procedure applies to Unix systems.

For more information on how to configure the NetWorker DMA to work with a Mirapoint appliance, see:

For more information on configuring and supporting Legato's NDMP, refer to the Legato NetWorker Administrator's Guide provided with your Legato software.

Overview of the Configuration Process

Before using selective restore, you might need to modify your basic NetWorker configuration so that it produces a history file each time you perform a backup.

Prior to release 3.6, Mirapoint required the history setting be no (n). As of 3.6, the history file settings must be yes (y).

Setting the DMA Type in the Mirapoint Software

As of Release 3.6, you can add the specific NDMP DMA you are using to the Mirapoint appliance configuration. Changing your DMA setting allows the Mirapoint NDMP service to adjust itself to the requirements of each approved DMA.

To set the NDMP DMA, do the following:

1. Open a telnet window, and log in to Mirapoint as an administrator.
2. Type the following CLI command:
    Ndmp Set Dma Legato
        To verify your NDMP DMA setting, use the Ndmp Get Dma command.
3. Log out.

Modifying Your NetWorker DMA Setup

This procedure assumes you are using a Solaris workstation.

Your Mirapoint client configuration in the Legato DMA must be modified so that it produces a history file. Do the following:

1. Open the nwadmin program by entering the following the following command at the command-line:
nwadmin &
2. Login as an administrator with full access, or as root. The Main Menu displays.

3. Select Clients from the top menu bar, and then select Client Setup from the drop-down menu.

4. Select the client whose setting you want to modify from the list in the Clients: field.
5. Verify that the Save set: attribute is set to /usr/store. If this directive does not appear on the list, do the following to add it:
a. Type /usr/store in the Save set: text box.
b. Click add.

6. Use the scroll bar to move through the list of client attributes until Application information: displays.

The following environmental variables are required:
  • HIST=y
  • TYPE=image
  • UPDATE=y
If any or all of these variables do not appear on the list below the Application information: text box, type the one not present on the list in the Application information: text box, then click add. Repeat this process to add the other variable if they are also missing from the list.
 
If either or both are present on the list but are not correctly set, change them by doing the following:
 
a. Highlight the variable (for example HIST=).
b. Type HIST=y in the Application information: text box.
c. Click change.
d. Repeat for the TYPE= variable if it is not set to image, and for UPDATE= if it is not set to y.
 
7. Click Apply.
8. Select File from the Clients pop-up window's top tool bar. From the drop-down menu, select Exit.
