Reserving a Device for a Job

To reserve a tape device for a certain job, specify the JOB parameter on the VARY command. For example, to reserve device 01A0 for the job named PAYROLL on all systems, issue the following command:

VARY 01A0 JOB=PAYROLL GLOBAL

Note: If a device is reserved for a job on the local system only, then the device can only be used by that job on that system. No job can use the device on any other system, including the job for which the device is reserved locally. The device must be reserved for the job on all systems for the job to be allowed to allocate the device on any system.

Note: Tape swap is not affected by job reserve processing.
