Primary HA host failure

If the secondary high-availability (HA) host detects a primary host failure, it automatically takes over the responsibilities of the primary HA host and becomes the active system.

When a primary HA host is recovered from a failover, it does not automatically take over the active status in the HA cluster. Instead, the secondary HA host remains the active system and the primary host acts as the standby system.

Important: You must switch the primary back to the active status after successfully recovering from a primary failure. See Switching a primary HA host to active.
