DFSMStvs is unable to locate previously hardened data when reading from the system log during the backout of a task. This implies that data on the system log has been lost. The integrity of the system log is suspect.
DFSMStvs is quiesced to let as many tasks complete as possible. Any tasks that enter backout from this point on are not backed out. DFSMStvs forces the next start to be cold to ensure that no data is read from the system log.
None
Because the next DFSMStvs start must be cold, ensure that any units of recovery that were in-flight are recovered. If the error condition persists, contact the IBM® Support Center.
After the cold start, any data sets for which recovery was owed are most likely left in a damaged state and need to be recovered manually. If the data sets are forward recoverable, then their forward recovery logs might also be damaged. IBM recommends that you manually recover the data sets (without using forward recovery), take backups of them and of any other data sets that use the forward recovery log, and then delete and redefine the forward recovery log.
