Autopath Feature Assumptions

You can make the following assumptions about the Autopath feature:

It is designed to improve average availability of tape drives over a long period of time.
It should help provide the most resources to the busiest systems.
In the short run, there is no guarantee that any specific job will benefit from Autopath. This feature is designed make more devices available on busier systems, not to move specific devices for specific jobs.
Note: We recommend that you not allow allocation recovery messages to remain outstanding while waiting for a device to be attached. This delays allocation and there is no guarantee that a device will be available to be attached.
In some cases, certain system conditions can prevent Autopath from obtaining needed tape drive resources. For example, Autopath may be unable to act when two or more systems frequently invoke allocation recovery.
