Emcli Stop_Blackout Hangs if the Target Agent is Shutdown After the Blackout is Started (Doc ID 841447.1)

Last updated on DECEMBER 11, 2019

Applies to:

Enterprise Manager Base Platform - Version to [Release 10.2 to 11.1]
Information in this document applies to any platform.
This problem can occur on any platform.


A blackout is being created using the following set of steps :

- Create a blackout using :

emcli create_blackout -name="blackout_name" -add_targets="<target_name>:<target_type>"
-reason="test" -schedule="duration:-1"

- Check that the blackout has started successfully using :

emcli get_blackout_details -name="blackout_name"

- Check that the details of this blackout have been added to the <AGENT_HOME>/sysman/emd/blackouts.xml file.   

-  Stop the agent which is monitoring the above target.
-  Try to stop the blackout using :

emcli stop_blackout -name=blackout_name

The command hangs without any output and does not return back to prompt.

- Use ctrl+c to cancel the command and check the details of the blackout :

emcli get_blackout_details

Output will show that the status of the blackout is "Full Blackout - Stop
Failed "

Name                   Created By  Status

10:23:49  none      none                 Asia/Calcutta  +00:00 

If a blackout is created using similar set of steps from the console, the blackout goes to "Full
Blackout - Stop Failed ".

The above behaviour does not occur if the Agent is already down when the blackout is created or
if the agent is running but the blackout details have not been written to the <AGENT_HOME>/sysman/emd/blackouts.xml file.
