Issue

Continuous HW Assist keep alive errors
Those cleared after a few minutes, in both nodes of an HA pair.
EMS.Log Example:

14:11:29 +0100 [node_name01: cf_hwassist: cf.hwassist.recvKeepAlive:info]: hw_assist: Received hw_assist KeepAlive alert from partner(node_name02).

The errors follow a timing pattern.
Example: every 7:30 minutes.
Command storage failover hwassist show outputs shows the following error:

cluster::> storage failover hwassist show Node ----------------- node-01 Partner: node-02 Hwassist Enabled: true Hwassist IP: 10.XX.XX.X Hwassist Port: 4444 Monitor Status: active Inactive Reason: - Corrective Action: - Keep-Alive Status: Error: did not receive hwassist keep alive alerts from partner. node-02 Partner: node-01 Hwassist Enabled: true Hwassist IP: 10.XX.XX.X Hwassist Port: 4444 Monitor Status: active Inactive Reason: - Corrective Action: - Keep-Alive Status: Error: did not receive hwassist keep alive alerts from partner. 2 entries were displayed.

Command storage failover hwassist test outputs shows timed out error:

cluster::> storage failover hwassist test -node * Info: No response from partner(node-01).Timed out. Info: No response from partner(node-02).Timed out.
