• Closed as program error.

Error description

• The Tivoli Storage Manager for Space Management (HSM) dsmscoutd
  may incorrectly issue the following error to the dsmerror.log:
  .
    ANS9084E dsmscoutd: /filesystem is not managed or not locally
             managed by space management.
  .
  In some environments, these errors can be reported multiple
  times per second across every non-owner GPFS node in the
  cluster.  This can cause the dsmerror.log files to grow in
  size very quickly.
  .
  Customer/L2 Diagnostics:
  Review the dsmerror.log files on each node in the cluster.  If
  ANS9084E errors are being reported constantly, this problem
  can apply.
  .
  Initial Impact:
  Medium
  .
  

Local fix

• Reduce distributed migrations if possible and implement
  dsmerror.log pruning options to limit the size of the file
  (ERRORLOGRETENTION and ERRORLOGMAX) until a fixing level
  can be applied.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: TSM HSM client version 6.1.3 and 6.2.0 on    *
  *                 AIX GPFS and Linux GPFS platforms.           *
  ****************************************************************
  * PROBLEM DESCRIPTION: See ERROR DESCRIPTION.                  *
  ****************************************************************
  * RECOMMENDATION: Apply fixing level when available. This      *
  *                 problem is currently projected to be fixed   *
  *                 in levels 6.1.4 and 6.2.1. Note that this    *
  *                 is subject to change at the discretion of    *
  *                 IBM.                                         *
  ****************************************************************
  Upon a distributed migration in a multi-node GPFS cluster
  environment, a lot of misleading ANS9084E errors may be issued
  in the dsmerror.log.
  

Problem conclusion

• The problem has been fixed so that it no longer occurs.
  

Temporary fix

• An interim fix is currently targeted for version 6.1.3.4. Note
  that until the interim fix is actually available, this
  information is subject to change at the discretion of IBM.
