Error description

  • A migration process on the Tivoli Storage Manager can hang
    if it is part of a multi process migration. For example,
    if 4 processes are used for migration, one of them can
    hang and will not cancel.
    -
    This is most likely to occur if data deduplication is also
    in use.
    -
    The problem is more likely to occur at software version
    6.1.3 due to other related changes in that level.
    Tivoli Storage Manager Versions Affected:
    6.1 on all platforms
    Customer/L2 Diagnostics:

    Initial Impact:
