The VARY AVAILABLE command releases a not-available device by VARYing that device online and making it available for allocation. In addition, an operator may use the command to wake jobs waiting for a device on the z/OS allocation queues.
For example, two jobs have gone through allocation recovery and an operator has responded WAIT to the IEF238D messages and NOHOLD to the IEF433D messages. If the operator issues a VARY AVAILABLE command to any device that could satisfy both job requests, then the command wakes both jobs and sends them through allocation again.
You can specify the LOCAL, EXTERNAL, GLOBAL, or systemid parameter to indicate the scope of the status change.
Note: For more information, see the Statement and Command Reference Guide.
