** [tickets:#2998] clm: send PLM response if node down comes**
**Status:** accepted
**Milestone:** 5.19.03
**Created:** Fri Jan 11, 2019 04:28 PM UTC by Alex Jones

**Owner:** Alex Jones
If a LOCK admin command from PLM is issued on a HE or EE, CLM sends a tracking
request to AMF to validate and start the shutdown. When the START track is sent
CLM waits for a response from AMF. Because the request is coming from PLM, the
time supervision is set to UNKNOWN, which means the response has no time limit.
If the node crashes before AMF responds to CLM, then PLM never gets a response
from CLM and doesn't transition the EE or HE to LOCKED state. CLM needs to send
a response to PLM if it detects node down and there is a pending PLM operation
on that node, and no response has yet been sent back to PLM.
