A mountable optical volume resides on one side of an optical disk cartridge. The ISMF Mountable Optical Volume Application allows you to maintain optical volumes in an optical library through the use of the AUDIT, EJECT, and RECOVER line operators, or through the use of the AUDIT command. You can use line operators and commands to perform audits against volume lists, single volumes, or full libraries, eject optical disks from the library, and recover data stored on an optical disk that can no longer be read.
Restriction: You cannot use the ISMF RECOVER line operator to recover from second backup copies of objects. To recover a primary volume from the second object backup copy, use the MODIFY OAM command. See Starting the OAM Volume Recovery utility for further details on this procedure.
