The migration to tape of the VSAM data set with the name dsname was successful, but there was an error in creating an entry in the TTOC for this migration. An attempt was made to mark the MCV record of the tape volume ineligible for deletion and this attempt failed. This tape must be marked ineligible for deletion because there is no TTOC entry for the migration copy of the data set. Recycle processing cannot move this migration copy to another tape. When recycle processing empties the tape except for this last VSAM data set, the TTOC indicates there is no more valid data on the tape. However, the unrecorded migration copy is still there. If an attempt is made to delete the volume with the DELVOL command and the volume is not marked ineligible for the DELVOL command, the only copy of a user’s data set will be lost.
The data set remains migrated; DFSMShsm processing continues.
Issue a FIXCDS command to set the flag MCVFNDLV on. This marks the MCV record of the volume volser ineligible for deletion and protects the VSAM data set that is not listed in the TTOC. This VSAM data set dsname should be recalled and a FIXCDS command should be issued to set the flag MCVFNDLV off. Now that the TTOC is in sync with the actual valid data on the tape, it is safe to allow normal processing on the tape volume.
