When an optical volume is ejected from a library, it must be assigned to a pseudo library. In previous releases, shelf resident volumes were associated with a pseudo optical library that represented volumes of that media type. Pseudo libraries do not have a device type association.

If the volume being ejected already has a pseudo library name associated with it in its volume record, that pseudo library continues to be used unless it is overridden with the LIBRARY keyword on the EJECT command. If the volume being ejected does not already have a valid pseudo library associated with it, the default pseudo library associated with the library from which the volume was ejected can be used, if one exists, unless it is overridden with the LIBRARY keyword on the EJECT command. If the optical volume being ejected does not already have a valid pseudo library associated with it, or the library from which the volume was ejected does not have a default pseudo library in its definition, or the LIBRARY keyword was specified on the EJECT command, the system issues message CBR2602A or CBR2603A, or both.

CBR2602A Eject pending for volser in r-library-name. Default pseudo library
         is p-library-name. Reply 'U' to use, or 'R' to respecify.

CBR2603A Specify pseudo library name for volume volser.

If the volume being ejected has an invalid pseudo library associated with its volume record and the library from which the volume is being ejected has a default pseudo library in its SCDS definition, message CBR2602A is issued. This message asks if the default is to be used or if another pseudo library name is requested.

If the library from which the volume is being ejected does not have a default pseudo library in its SCDS definition, or “R” was replied to message CBR2602A, message CBR2603A is issued. This message requests a pseudo library name to assign the volume to when it becomes shelf resident.

CBR2604I Volume volser cannot be assigned to pseudo library p-library-name, it is
         not a valid pseudo library definition in the active SMS configuration.

CBR2603A Specify pseudo library name for volume volser.
