SQL1768N Unable to start HADR. Reason code = “1”

I was asked to troubleshoot a problem related to a HADR start

and issued the following db2 command:

$ db2 start hadr on db MY_DB as standby

I got back the following error description

SQL1768N Unable to start HADR. Reason code = “1”.

It turns out the the users had attempted to set HADR up with circular logging , archive logging is required
to run HADR
