“Heartbeat timeout from ACTIVE” — When the timeout occurs, this alarm 

is only logged on the standby side. After logging the alarm, the servers 

should have interchanged, so that the:

●

Alarm normally resides on the newly active (healthier) server

●

Previously active server has backed down to the standby role

As potential causes, either the:
Alternate side is in normal shutdown (irregular, but possibly innocuous).

1. On the standby server, look for occurrences of the stop command, 

either from the:

- Web interface, by:

a. Selecting View System Logs

b. Selecting Platform command history log

c. Specifying the Event Range for the appropriate time frame

d. Matching the “Stop” pattern

- Linux command line, by entering listhistory

Note: From the system’s perspective, this is normal behavior. 
However, in terms of potential service outage due to human error, this 
is quite irregular. Shutting down a server effectively downgrades a 
duplex-, high-, or critical-reliability system to an unsupported 
standard-reliability system.
