action #94765

Updated by livdywan about 3 years ago

## Motivation 
 See #93050#note-15 

 ## Acceptance criteria 
 * **AC1:** openqaworker12 is verified to be usable use for production multi-machine tests 
 * **AC2:** Same as AC1 but after additional reboots to ensure reboot stability 
 * **AC3:** openqaworker12 is controlled over salt 

 ## Suggestions 
 * Look into the error report of #93050#note-15 
 * Find a good "multi-machine test scenario" to verify 
 * Bring the machine up with a dedicated worker class selection for investigation, e.g. `openqaworker12,tap` 
 * Fix any found problems 
 * Accept salt key for openqaworker12 on osd `sudo salt-key -y -a` 
 * Apply full salt state and check for success 
 * Unpause "openqaworker12: host up alert" 
 * Crosscheck monitoring results 

 ## Further details 
 * Remove As alternative to fixing multi-machine we can also remove the "tap" from worker class settings and bring back the machine for single-machine jobs only first
