UNABLE TO SELECT A VOLUME FOR UNIT <xxxxxxxx>

Reason:

During volume selection, CA Allocate checks the validity of the unit name that was specified by the user or with a SET &UNIT= statement. If the unit name cannot be found, or it is a unit address such as 1A0, this message is issued. CA Allocate bypasses volume selection for this allocation request. A JCL error is issued when an invalid unit name is detected. The allocation could end normally in the case of the unit address. The user would also have to specify in the JCL the correct permanently mounted volume serial number.

Action:

Review the contents of the storage pools defined in the member specified in sysparm PLSSTRMB.
