Error description

  • After an upgrade of a TSM 5.5 Server to TSM 6.1 (both 32bit) and
    later on a migration of this TSM 6.1 Server from 32bit to 64bit
    (same platform),
    the space reclamation fails with following errors in the ACTLOG:

    .
    During the upgrade process to TSM 6.1 on the 32bit system, a
    column in the internal AF.Clusters table got initialized with a
    size of 24 bytes. When the TSM 6.1 Server has then been migrated
    to a 64bit system (on the same platform), the size of that
    column did not change though a 64bit TSM 6.1 Server expects this
    column to have a minimum size of 32 bytes,
    .
    In this specific case, the TSM 5.5 Server has been upgraded to
    TSM 6.1 both running on Windows 32bit and later on this TSM 6.1
    Server has been migrated to a Windows 64bit system.

    reclamation is ended for volume 123456L3. An internal server
    error was detected.~
    .
    The issue is that in the server table AF.Clusters TSM keeps
    track of current output volumes used by this particular
    NODE/FILESPACE.  This list of current output volumes is used as
    a hint during processing to determine the best/most likely next
    volume(s) to use for output for a new operation.
    The specific issue is that the data for this column is not
    correct.  It is expected to be of a minimum length of 32 bytes
    but in the cases where this fails it is only a length of 24
    bytes.  So, the error is raised and the operation fails because
    TSM was not able to use the existing current output volume hint
    that is supposed to be in place.
    .

Local fix

  • In case tapes are needed, the MOVE DATA command can be used to
    empty (some of) the tapes.
