Error description

  • Version 6.1 Tivoli Storage Manager servers configured as
    library managers may invalidly attempt to reclaim drives
    being used by library clients.  Drive reclaim is intended to
    prevent resources from being hung out for long periods of time
    should a library client become hung or stop running for any
    reason. The library manager will attempt to reclaim a drive(s)
    if there has not been a confirmation of use received within the
    LIBSHRTIMEOUT setting.  The default LIBSHRTIMEOUT is 15
    minutes.  A message similar to the following is issued to the
    activity log when a drive is reclaimed for use by others:
    .
    14.09.2009 08:24:47  ANR8925W Drive XXXXX in library XXXXX has
    not been confirmed for use by server XXXXX for over 900 seconds.
    Drive will be reclaimed for use by others.
    .
    If this problem is encountered, the drive reclaim may occur
    invalidly.  The drive should not be reclaimed if the mount
    occurred less than LIBSHRTIMEOUT minutes before.  Here is an
    example of a message issued when a volume is mounted:
    14.09.2009 08:21:18      ANR8337I LTO volume XXXXX mounted
    in drive XXXXX (/dev/rmt1).
    Note:  The volume was mounted at 08:21:18 and the drive was
    reclaimed at 08:24:47 which is less than the LIBSHRTIMEOUT.
    .
    Tivoli Storage Manager Versions Affected:
    All Version 6.1 Tivoli Storage Manager servers configured as
    library managers
    .
    Initial Impact: Medium
    .
    Customer/L2 Diagnostics:
    A trace on the lib manager with PVR MMS classes will show
    symptoms similar to the following if this problem is
    encountered:
    .
    trace enable PVR MMS (the key subclass is PVRMP)
    .
    06:36:00.521 ■164782■pvrmp.c■1689■pvrConfirmSharedMountPoint
    :Confirming shared mp 0 for XXXXX - class XXXXX, lib XXXXX,
    devType 21, format 0, drive XXXXX, vol XXXXX.
    ...
    06:39:47.046 ■19■pvrmp.c■8455■UpdateAllMpPings:Begin
    updating/reporting all stored mp pings.
    06:39:47.046 ■19■pvrmp.c■8506■UpdateAllMpPings:Error mp
    time stamps don't match 09/14/09 04:20:38, 09/14/09 04:36:00.
    06:39:47.047 ■19■pvrmp.c■8516■UpdateAllMpPings:Cannot find
    mp trying to find using volname XXXXX.
    ...
    If there is no trace point with
    "Error mp time stamps don't match"
    then this APAR most likely does not apply.
