16.3.6 Handling power-related events

ClosedContext

Power actions are considered NODEMODIFYURL events and are not recorded by default, but you can configure Moab to include power-related events in the logs. Also, if a node fails to turn on (or off), it's best to associate a reservation on the failed node so that Moab won't keep trying to perform the power action over and over.

To configure Moab to record power-related events

  1. Modify the RECORDEVENTLIST parameter.

    RECORDEVENTLIST +NODEMODIFY

    Power-related events are logged to the Moab log file.

To put a reservation on a node that fails to perform a power action

  1. Configure the NODEFAILURERSVPROFILE attribute of RMCFG and create an RSVPROFILE with a high duration.

    RMCFG[torque] NODEFAILURERSVPROFILE=failure
RSVPROFILE[failure] DURATION=3600

    Nodes that fail to power on or off have a 1-hour reservation placed on them.
