Veritas NetBackup™ Appliance High Availability Reference Guide
Introduction to the NetBackup 53xx high availability operations
In an operational high availability (HA) configuration, you can run the following operations from the NetBackup Appliance Shell Menu:
This command transfers the services and workload of one node to the other node. Before you upgrade the HA node that runs the MSDP services, you must first run this command to switch the services over to the partner node.
Note:
You cannot perform this operation with the virtual hostname or the virtual IP address. You must use the physical host name or the physical IP address of the specific node.
A switchover automatically initiates email notifications to report the service status changes.
Use this command to check the status of the HA configuration and all the HA-related services.
Use this command to remove a node from the HA setup to perform maintenance, or when you need to replace or re-purpose a node. You must use the physical host name or the IP address of the node to remove it from the HA setup.
You can add the node back to the HA setup only if you do not perform a factory reset on it after removing it from the HA setup. If you perform a factory reset on a removed node, it reverts the node back to a non-HA appliance.
Note:
If you attempt to run a factory reset or initiate a rollback to a non-HA checkpoint on a node in an HA setup, the HA setup can malfunction.
If you remove a node from the HA setup to replace it or re-purpose it, you must also do the following:
Disconnect the Ethernet cables from the removed node.
Disconnect the FC cables from the removed node.
Perform a factory reset on the removed node.
Note:
If you remove a node from the HA setup, the node that remains in the setup cannot be upgraded. HA nodes must be upgraded from within an HA setup that contains both nodes.
GetAssetTag
You can retrieve the asset tag of the HA configuration to identify the hardware devices in your working environment.
The asset tag works as the identity of an HA configuration. Once the HA configuration is complete, an asset tag is automatically attached to each firmware of the two nodes and the shared Primary Storage Shelf. To ensure that the changes take effect, Veritas recommends that you restart the two nodes.
The values on the three components are identical. If the values vary, restart the node or nodes with the different value from the shared Primary Storage Shelf.
For the detailed usage of the respective commands, refer to NetBackup Appliance Commands Reference Guide.
