Logical volume cartridge entry processing

DFSMSrmm processes new logical volumes and imported volumes differently at entry time.

DFSMSrmm automatically defines both new logical volumes and imported logical volumes if they are not defined to DFSMSrmm already. DFSMSrmm does not define rack numbers for these volumes.
DFSMSrmm checks the rack number for a logical volume that is already defined to DFSMSrmm. If the rack number does not match the logical volume's volume serial number, DFSMSrmm fails the entry request and issues message EDG8189I. If the rack number matches the volume serial number, DFSMSrmm continues processing the request. DFSMSrmm frees the rack number for the logical volume so the logical volume is no longer associated with the rack number.
DFSMSrmm checks that an imported logical volume that is already defined to DFSMSrmm, is also a logical volume and does not reside in a virtual tape server library. When a logical volume is being imported, DFSMSrmm checks that the volume, if it is already defined to DFSMSrmm, is correctly defined as an exported logical volume. DFSMSrmm issues message EDG8183I when the entry request fails.
DFSMSrmm accepts new scratch logical volumes that match existing scratch logical volumes. DFSMSrmm updates the volume information with information for the new volume. If the volume serial numbers match but the volume is not defined as a scratch volume, DFSMSrmm fails the entry request and issues message EDG8182I.

Note: If you use REJECT commands, you have to convert from the use of REJECT commands in order to use the PRTITION and OPENRULE commands. See Converting REJECT commands to PRTITION and OPENRULE commands for information about converting from the use of REJECT commands.

Table 1 describes the entry processing decisions DFSMSrmm makes.

Table 1. DFSMSrmm entry processing decisions

Volume is not defined; no REJECT.	Added	Not applicable	Added scratch or private	Added private
Volume is not defined; REJECT.	Ignored	Not applicable	Ignored	Ignored
Volume is defined for use with z/OS.	Updated	Not applicable	Updated	Updated
Volume is defined for use with VM.	Ignored	Not applicable	Ignored	Ignored
Rack number associated with the volume is the same as the volume serial number.	Updated	Not applicable	Updated; DFSMSrmm clears the rack number.	Updated; DFSMSrmm clears the rack number.
