Problem summary

• ****************************************************************
  * USERS AFFECTED: TPC 4.1.x users who install agents (SRA or   *
  *                 Data Agents) on AIX and use them to scan     *
  *                 GPFS file systems.                           *
  ****************************************************************
  * PROBLEM DESCRIPTION: During TPC scan, the agents enter       *
  *                      the snapshot directory of the GPFS      *
  *                      file system and collect information     *
  *                      about the files there. Because of       *
  *                      this, the number of files scanned is    *
  *                      much larger than the real number of     *
  *                      files in the file system.  The scan     *
  *                      log displays the number of scanned      *
  *                      files:                                  *
  *                       AGT0144I: X total files scanned        *
  ****************************************************************
  * RECOMMENDATION:                                              *
