failed due to missing data set initialization records. Specifically,
the log records which format space map and header pages were missing.

code of 8.

Problem determination
 This message was preceded by message
DSNU513I which identifies the log RBA range being applied. Run the
print log map (DSNJU004) utility for the table space in question over
the indicated log RBA range.
 This will show what log records
are present and may assist in determining if a log data set has been
damaged or deleted, or if the BSDS has been damaged. If damage to
table space DSNDB01.SYSLGRNX is suspected, recover it and attempt
the earlier failing recovery again.
