Veritas NetBackup™ Appliance High Availability Reference Guide

To recover the failure node

1. On the node that works properly, log on to the NetBackup Appliance Shell Menu as admin.
2. Go to Main > Manage > HighAvailability.
3. Remove the failure node with the following command:

   RemoveNode HostName

   Where HostName is the host name of the disaster node.

   Note:

   To avoid any data loss, make sure that you perform the following procedures after the node is removed:

   Disconnect the Ethernet cables from the removed node.

   Disconnect the Fibre Channel cables from the removed node.

4. On the removed node, log on to the NetBackup Appliance Shell Menu as admin.

   If the failure is severe enough to bring the node down, and the NetBackup Appliance Shell Menu is not accessible, refer to the section About disaster recovery in the document NetBackup Appliance Administrator's Guide.

5. Go to Main > Support.
6. Reset the removed node to its factory default settings with the following command:

   FactoryReset

7. Perform the initial configuration on the removed node from the NetBackup Appliance Shell Menu.

   For detailed instructions, refer to the section Performing the initial configuration on the partner node for a NetBackup 53xx high availability configuration from the NetBackup Appliance Shell Menu in the document NetBackup 53xx Appliance Initial Configuration Guide.

8. Once the initial configuration is complete, you can add the configured node back to the HA configuration as follows:

   • On the node that is in the HA configuration, log on to the NetBackup Appliance Shell Menu as admin.

   • Go to Main > Manage > HighAvailability.

   • Add the configured node to the HA configuration with the following command:

     AddNode hostname

     Where hostname is the short host name or the fully qualified domain name (FQDN) of the configured node.

   • When the following message appears, make sure that you checked the SSH ECDSA fingerprint directly on the partner node:

     Do the fingerprint values match? [yes, no] (no)

     To guarantee that the network is safe, you need to confirm that the SSH ECDSA fingerprint of the partner node is correct. For the instructions on how to check the identity of the appliance, refer to NetBackup Appliance Command Reference Guide.

     If the values match, enter yes.

   • After the pre-check is passed, when the following message appears, enter a reissue token to trust the host ID-based certificate:

     Reissue token is mandatory. Enter the reissue token for the required host to obtain a host-ID based certificate:

     For more information about security certificates, refer to the chapter Security certificates in NetBackup in the document NetBackup Security and Encryption Guide.

   • When the following message appears, enter yes to continue the node adding procedure:

     >> Do you want to continue? [yes, no] (no)

     When a message shows you that the procedure is successful, the HA configuration is complete.
