Ending—(JES3).
JDST1DRN: Drained—device is configured but is not available (JES2).
Offline—(JES3).
JDST1ACO: Device is active but varied offline (JES3).

Second status byte:

JDST2STE: Startable—device is not ready for work but has enough resource to start.
JDST2STG: Starting—device is being started.
