2. Task 7 Recover the Application and User Data To recover the application and user data that was on the NetWorker server 1 Log in as root 2 Load and inventory the devices This ensures that the NetWorker server can recognize the location of each volume Note If you load a clone volume you must either delete the original volume from the media database or mark it as suspect in the media database If you are using a clone volume it will be used for the remainder of the recovery process 3 Run the nwrecover program 4 Mark all of the directories or files that you want to recover A Important Do not recover any UNIX operating system boot files that should not be overwritten during a recovery For more information on boot files see Prerequisites on page 28 5 Click Start to begin the recovery Note By default the directed recover option is enabled when you install the NetWorker client If the directed recover option was disabled on the client before the disaster you need to explicitly set this option to disable directed recoveries to this client This option is set through the nsradmin command For more information about setting the disable directed recover option on the NetWorker client refer to the Legato NetWorker Administrator s Guide UNIX Version Task 8 Perform a Test Backup and Recovery To test the server recovery process 1 Perform a test backup or recovery to make sure the server is fully recove

To perform a complete cluster recovery in the event that both cluster nodes Node_A and Node_B have failed 1 Ensure that the system disk of each node is configured using the same partitioning scheme and drive letter that was in use prior to the loss of the node Note On each cluster node the repaired or replaced system disk must have the same partitioning scheme disk format and drive letter configuration that was in use prior to the node failure However drive letter assignments of available volumes during Windows setup may cause the system disk drive letter to change Therefore prior to reinstalling the Windows operating system disconnect the SCSI bus if the shared drives are being enumerated before the local drives 2 Format and verify the system disk on each node 3 On each node reinstall Windows to the partition it occupied before the node failure During Windows setup on each node verify that the domain controller is available and that each potential node is able to join 4 Delete the MSCS folder on the quorum disk 5 On the quorum disk run the chkdsk command 132 Legato NetWorker Release 7 0 Disaster Recovery Guide Chapter 7 Microsoft Cluster Disaster Recovery Windows 2000 and NET 6 For Windows 2000 systems install the Cluster Service on Node_A a While Node_B is still detached from the shared SCSI bus using the Control Panel Add Remove Programs tool add the Windows component Cluster Servi

8. Legato NetWorker Release 7 0 Disaster Recovery Guide 67 NetWorker Server Recovery Requirements During the installation keep the following points in mind e Ifthe NetWorker installation kit is available on a shared drive you can install it over the network e To update the NetWorker software first recover the server to its state immediately prior to the disaster then perform the update e You do not need to reload the license enablers they will be restored later in the recovery process e Because the NetWorker mmrecov command is case sensitive the NetWorker installation path must be in the same case as the original For example C Program Files Legato nsr is not same as C Program Files legato NSR 2 Install any NetWorker patches that were in use prior to the disaster Task 2 Configure the NetWorker Server To configure the NetWorker server 1 Inthe NetWorker Administrator program open the NetWorker server s Client resource and verify that the Aliases attribute in the Preferences tab contains the correct information For example aliases for a computer named kingdome might be kingdome kingdome seattle washington com 2 Create and configure the NetWorker server s Device resources Do not mount or relabel any volumes in the devices For more information refer to the Legato NetWorker Installation Guide Microsoft Windows Version e If you are using an autochanger with Removable Storage disabled a Star
