TPCEDLXT Exit

The TPCEDLXT exit routine invokes elimination logic, which marks devices ineligible in the EDL (during allocation) and removes them from the offline device list (during allocation recovery). By defining elimination logic, you can remove certain devices from consideration in almost every condition. However, if the devices you remove are the only ones a job can allocate or if the only remaining devices are reserved for other jobs, TPCF ignores your elimination logic so that the job can allocate a device.

Note: Elimination logic does not affect selection of devices in SWAP processing.
