Error description

  • When data from a node is being stored into multiple directory
    container storage pools, it is possilbe that the data will be
    stored into the wrong container with a different storage pool id
    than the one the container belongs to.
    This is only seen when includes are used and the files are
    larger than 25MB.
    For example, node NODE1 is backing up the folder \temp\Folder1
    to IBM Spectrum Protect server SERVER1. In \temp\Folder1, we
    have the following four files -
    FileA.aaa  50MB
    FileB.bbb  50MB
    FileC.aaa  50MB
    FileD.bbb  50MB
    The include exclude file has the following include statements
    specified:
    include \temp\Folder1\*.aaa MGMT1
    include \temp\Folder1\*.bbb MGMT2
    At SERVER1, there are two management classes named MGMT1 and
    MGMT2 which tie out to two directory container storage pools
    named CONT1 and CONT2.  As a result of this APAR, when backup of
    \temp\Folder1 occurs, it is possible that data stored into a
    container for CONT1 actually belongs to CONT2 or vice versa.
    This can lead to problems when attempting to empty and delete
    containers.  Running move container against the affected
    container can also result in extents being marked damaged.
    Audit container will not detect or fix the problem.
    Once this APAR is addressed new incoming data will be stored in
    the correct containers.
    This APAR is similar to the issue described in IT17718.
    Customer/L2 Diagnostics:
    To confirm if the problem is being encountered, the following
    can be run via a cmd prompt:
    db2 connect to tsmdb1
    db2 set schema tsmdb1
    db2 "select sdcl.poolid as sdcl_poolid, sdcn.poolid as
    sdcn_poolid, sdcl.cntrid as cntrid, sdcl.refcount as refcount,
    sdcl.flags as flags, count as count from sd_chunk_locations sdcl
    inner join sd_containers sdcn  on (sdcn.cntrid=sdcl.cntrid)
    where sdcl.poolid!=sdcn.poolid group by sdcl.poolid,
    sdcn.poolid, sdcn.cntrid, sdcl.cntrid, sdcl.refcount, sdcl.flags
    for read only with ur"
    If the select returns some rows of data, then you are most
    likely affected by this APAR or APAR IT17718.
