Error description

  • Page validation during database backup processing is incomplete
    and can result in corrupt pages not being detected.
    Beginning with the introduction of Tivoli Storage Manager server
    version 7.1.1.000, the Server began leveraging a DB2 technology
    to validate database pages during database backup operations.
    Page validation is used to uncover structural corruption within
    the database.
    Under a set of known and unavoidable conditions, this page
    validation feature can fail to properly detect and report some
    bad pages within the database.  This is caused by DB2 APAR
    IT13905.
    This is a MDVPARTL APAR for IT11954.
    Customer/L2 Diagnostics:
    If structural database corruption is identified through
    diagnostics (see TechNote 1681275), but an ANR3260E error was
    not reported by the Tivoli Storage Manager server during
    database backups, then this APAR likely applies.
    Initial Impact:
    High
    Tivoli Storage Manager Versions Affected:
    All 7.1.1.000+ Tivoli Storage Manager servers.
