Hi All,
below is a snippet from an ASA pair in active/standby mode but with standby unit showing as failed.
suspect it is because of the SFR missing form the standby FW (only installed on the active unit). did the no monitor-interface service-module but made no difference.
question - is it a requirement for failover to work, that you need a firepower module installed on both devices? cannot find any docs on this. if not a requirement the failed state might be unrelated to the sfr missing then?
any suggestions?

You can (as you have) tell the ASA not to use failure of the Firepower service module as a trigger to failover, its complete absence will cause the Standby unit to not have identical configuration as the Active mate and thus be in a failed state.
