HWSNAME (High Watermark Setup Names)

Use the HWSNAME statement to:

Define, to JES3, all names by which users can reference a given device type to enable high watermark setup (HWS) processing.
Identify the characteristics of each device name for the specific JES3 complex. This statement can be used to define which device names are subsets of other device names. In general, the fewer the number of alternate names, the more restrictive the device name being defined. This ensures that initial allocation for devices that are reused from step to step is the most restrictive device. It also ensures that attempts to override passed or cataloged unit names are processed correctly. Non-HWS users are encouraged to supply HWSNAME information to take advantage of this function.
