Changing location information with EDG

You can use the EDG_EXIT100 installation exit to perform these tasks:

Specify a new location name or location type for a volume.
Clear the location name to prevent a volume from being assigned to a location.
Add a location name when one was not originally assigned in the disposition control file.

You can change the contents of the PL100_NAME and PL100_LOCTYPE fields to change location or name information. On input, the fields contain values set from the disposition control file.

DFSMSrmm checks the storage location name and type that you specify against the list of storage locations defined in the DFSMSrmm EDGRMMxx parmlib LOCDEF command. If you specified a storage location that is not defined to DFSMSrmm, DFSMSrmm treats the location as a loan location.

Use the PL100_INFO_CMOVE field to determine if a volume move is to be confirmed by checking for the bit that indicates that a later confirm move is required or is marked as already completed. Set PL100_SET_CMOVE or PL100_SET_NOCMOVE for move confirmation action. PL100_SET_CMOVE forces a later move. PL100_SET_NOCMOVE marks the move as already completed.
