About the Veritas Access 3340 Appliance upgrade

Veritas Access 3340 Appliance supports the following upgrade methods:

  • Rolling upgrade

    Use this method if the Veritas Access 3340 Appliance is configured and the appliance nodes are part of the Access cluster.

  • Node-by-node upgrade

    Use this method if the appliance nodes are in factory state.

Note:

The appliance nodes that are in Not in Access cluster state cannot be upgraded. You can reset a node to the default factory settings, and then upgrade the node.

Upgrade method

Description

Rolling upgrade

During a rolling upgrade, each node in the Access cluster is upgraded successively without stopping the Access cluster. Rolling upgrade minimizes the service downtime.

Download the required upgrade package to one of the nodes in the cluster and upgrade the node where the upgrade package is downloaded. The upgrade process copies and installs the upgrade package to other nodes in the cluster. During the upgrade, services switch between the nodes to keep the Access Appliance online. The services are down only when the services switch between the nodes.

If upgrade fails on one of the nodes, the update is automatically rolled back on all the nodes in the cluster and the nodes are restored to their earlier version.

Node-by-node upgrade

Warning:

Ensure that all the nodes are in factory state before you use this upgrade method.

Download the required upgrade package to each node, and then upgrade each node separately by installing the update on each of the nodes.

If the upgrade fails, the update is rolled back and the node is restored to its earlier version.
