Validating new values through ISMF

ISMF validates the NEW VALUE input for the use attribute to allow only ‘P’ or ‘S’. The NEW VALUE input for storage group is validated on the same selection entry panel; however, blanks are acceptable in this field.

ISMF does not validate the existence of the storage group in the active configuration; however, if the tape volume is library-resident, OAM provides the validation to ensure the following:

The volume’s storage group is defined in the current ACDS as a tape storage group.
The volume’s library is defined in the specified storage group.
The volume’s library is defined in the current ACDS as a valid tape library.
Note: If the tape volume is shelf-resident, only the first check is made.
