APAR PQ38991 addresses the problem. The fix was made available in fixtest
3.7.3.8. The fix is also in 3.7.4.0. The problem is MVS only, and affects the
CARTRIDGE devtype in levels 3.7.3.0 to 3.7.3.8, and in the 3590 devtype in
levels 3.7.1.0 to 3.7.3.8. Database backup, Export, and backupset operations
that generate more than one volume can be affected by this problem. The
recommendation is to install the fix, and create new tapes by repeating the
database backup, export or generate backupset operation.
