A CHECKIN LIBVOLUME or LABEL LIBVOL command with SEARCH=BULK is in progress. Load all volumes to be processed into the multi-slot entry/exit port of the given library within the time limit specified in the message.
The server waits until a REPLY command is issued, or until the time limit expires.
Insert the volumes into the library’s entry/exit port; and issue a REPLY command, along with the request ID, to tell the server that the volumes have been inserted.
