The SSMCNTL command rule provides several functions and among them the REMOVE one. What exactly this REMOVE function does? Does it delete the resource/stc/job from the SSM tables?
The command SSM REMOVE just sets the resource to MODE=PASSIVE. With MODE=PASSIVE, SSM will just monitor the resource status but won't issue any commands to match current and desired states. This mode is useful when a task is under maintenance and will be stopped and started several times out of SSM control.
To set MODE back to ACTIVE the command READD can be used:
SSM READD JOB=xxxxxx
