High Availability Firmware Upgrade did not complete on Primary

When a firmware upgrade is performed on a High Availability pair. The firmware upload was successful on the primary appliance and the boot option was selected for the new firmware. As expected, the new firmware was pushed to the backup HA unit and it rebooted. The backup unit then assumed active status. But the primary unit never rebooted. Using the management IP to check each unit revealed that the backup unit, now Active, had the new firmware. However, the primary unit now showed idle, still with the old firmware. Rebooting the primary unit did not help.
On current Active appliance (originally the backup unit):
Go to the High availability | Advanced page.
Click on the Synchronize Firmware button to push firmware to backup (idle) unit.
The firmware will pushed out to the idle unit; it will reboot and assume Active status again.
Test the network to ensure all traffic is passing normally.
