Error description

  • The Tivoli Storage Manager server "EXTEND DB" command uses the
    DB2 "ALTER DATABASE ADD STORAGE" command which is deprecated for
    DB2 10.5.
    Because of this, the server is still exposed to DB2 APAR  DB2
    APAR IT14021:
    "DB2 MIGHT TRAP ON "ALTER DATABASE ADD STORAGE" IF FILE SYSTEM
    DISK SECTOR SIZE IS NOT OF 512 BYTES"
    
    
      Tivoli Storage Manager Versions Affected: 7.1
      Customer/L2 Diagnostics (If Applicable)
    Under the APAR condition, there is no error returned upon the
    "EXTEND DB" initiated "ALTER DATABASE ADD STORAGE" when NO FILE
    SYSTEM CACHING and disk sector size is not 512 bytes.
    This can result in the DB2 trap with similar output in
    db2diag.log:
