10.7. Adding a New Hardware Device in an Active Cluster

When you add hardware devices to an active cluster, you add them one node at a time.

To add hardware devices to a node in an active cluster, follow the same procedure as when you upgrade OS software in an active cluster, as described in Section 10.4. In summary:

• You must move the resource groups offline and stop HA services in the node before adding the hardware device.

• After adding the hardware device, make sure cluster processes are running and start HA services on the node.

To include the new hardware device in the configuration database, you must modify your resource configuration and your node configuration, where appropriate.
