The scratch volume encountered an error during mount processing that makes it unusable. The status of the volume is changed to private so that it is not selected for future scratch mounts. (Although the status has become private, it is not defined to a storage pool.)
Processing continues with another scratch volume.
See previous error messages to determine the cause of the mount failure, and correct the problem. If the problem is a mislabeled volume or unreadable label, relabel the scratch volume using the dsmlabel utility with the "-overwrite" option. If the volume is missing from its home slot, issue the AUDIT LIBRARY command against the library. If the volume has lost or corrupted VCR-data, relabel the volume. (This reinitializes the VCR-data by writing to the volume from beginning-of-tape.) Once the problem is corrected, update the status of the volume to scratch by using the UPDATE LIBVOL command.
