Upgrading SFW or SFW Basic in a Windows Server Failover Cluster enviroment

This section describes the tasks to be performed to upgrade SFW in a Windows Server Failover Cluster.

You must reboot the system after you upgrade SFW. However, rebooting an active cluster node causes it to fail over. To avoid this, you must first upgrade SFW on an inactive cluster node, switch the active cluster node to a second node, and then upgrade the first node.

In the following example, the two nodes in the cluster are Node A and Node B. Initially, Node A is the inactive cluster node and Node B is the active cluster node. After completing the following upgrade steps, Node A becomes the active cluster node. You can use the Failover Cluster console to make Node B the active cluster node after finishing the upgrade.

Step

Tasks

1

Review the pre-upgrade tasks to be performed.

See Preparing the SFW or SFW HA cluster nodes for upgrade.

2

Review the upgrade notes.

See SFW or SFW HA upgrade notes.

3

Prepare the nodes on the existing secondary site for the upgrade

See Preparing the secondary site for SFW upgrade in a Windows Server Failover Cluster environment.

4

If your configuration has DMP configured, then it is recommended to reduce the number of paths to each array to one, before you begin the upgrade.

For more information about the hardware and software prerequisites for DMP DSM installation, refer to Symantec Dynamic Multi-Pathing for Windows Installation and Upgrade Guide.

If you do not have DMP DSMs in your existing environment, but plan to add this feature during the upgrade, add the HBA(host bus adapter) hardware before performing the upgrade. Connect no more than one path from the new HBA to the storage array before the upgrade and DMP DSMs installation. Select the DMP DSM option or the appropriate DMP DSMs while running the installer.

5

Perform the upgrade steps on the inactive node (Node A)

Note:

After the upgrade is complete, the installer performs certain cleanup tasks and a command prompt is displayed for certain time. Ignore the prompt and continue with the further tasks. The command prompt closes after the cleanup tasks are complete. Do not close the command prompt before the cleanup tasks are complete. The cleanup tasks are aborted if you close the prompt.

6

Re-enable DMP on Node A, if applicable

See Reconnecting DMP DSM paths after the upgrade.

7

Prepare the nodes on the existing primary site for the upgrade

See Preparing the primary site for SFW upgrade in a Windows Server Failover Cluster environment.

8

Move the active node

See Making Node A the active node.

9

Perform task number 4, if applicable

10

Upgrade SFW on Node B

Note:

After the upgrade is complete, the installer performs certain cleanup tasks and a command prompt is displayed for certain time. You can ignore the prompt and continue with the further tasks. The command prompt closes after the cleanup tasks are complete.

11

Re-enable DMP on Node B, if applicable

12

Re-enable Volume Replicator after upgrading all nodes

See Re-enabling Volume Replicator in a Windows Server Failover Cluster environment.

13

Perform the remaining post-upgrade tasks

See About the tasks after upgrading SFW.
