	Once the above steps have been completed, including Activation of the High Availability Group, the cluster will monitor node health and if a failure is detected on the node with ownership of the Shared Storage Pool, an Automatic HA Failover event will be triggered. An automatic fail-over of the Storage Group will perform a failover of the storage group to the secondary, and all clients will regain access to the Storage Volumes and/or Network Share once the resources come online.

	Creation of a HA storage pool is the same as the process for creating a non-HA storage pool. The pool should be created on the appliance that will be acting as the primary node for the pool but that is not required. ~~As of~~ QuantaStor v3.17~~, encrypted HA storage pools can be created~~.		Creation of a HA storage pool is the same as the process for creating a non-HA storage pool.

Support for Encrypted Storage Pools is available in QuantaStor v3.17 and above.
