Ejecting an optical disk

Use the MVS LIBRARY EJECT command to eject a specific optical disk from an optical library. This command requires that the optical volume specified be controlled by the instance of OAM on which the command was entered. If the member name associated with the volume serial number is not the member name for this instance of OAM, the command fails and message CBR1068I is issued.

In an OAMplex, if a shelf-resident volume is entered into a library that is not known to an OAM in the OAMplex, that OAM removes it from its configuration and issues a message that the volume is no longer known. After that time, any read for that volume on that OAM fails with a volume unknown error. If the volume is ejected and assigned back to a pseudo library that is known to OAM, the volume is added back to the configuration.

The following command syntax ejects a specific optical disk:


>>-+-LIBRARY-+--+-EJECT-+-,volser-+-----------+-+----------+---><
   '-LI------'  '-E-----'         +-,LOCATION-+ +-,LIBRARY-+   
                                  '-,L--------' '-,LIB-----'

The following describes the values of the options for the EJECT command:

volser: Specifies the volume serial number of one of the two optical volumes on the optical disk that is ejected.
LOCATION: Prompts the operator to specify the new shelf location information for the ejected optical disk volumes.
LIBRARY: Prompts the operator to specify a pseudo library name to which the ejected volume will be assigned.

To eject an optical disk from an optical library, enter the following command:

LI EJECT,volser,LOCATION,LIBRARY

An optical disk can arrive in the input/output station without an operator request in the following ways:

The system can eject the optical disk as a result of the Library Space Manager utility running on that library.
The system ejects an optical disk volume if there are no scratch optical volumes in the optical library, no empty slots in the optical library, and the system is attempting to write to the storage group that has an out-of-space condition.
The system ejects an optical disk volume if the volume is expired.
The system ejects an optical disk volume if an unknown volume results in an error during volume entry sequence.
A storage administrator can specify an EJECT line operator next to an optical volume serial number on an ISMF Mountable Optical Volume List panel.
The system responds to a REMAP command against the library control inventory.

Tip: You can demount an optical disk on an operator-accessible drive by varying the drive offline.
