Error description

  • There is a race condition in the Tivoli Storage Manager Client
    where several producer threads attempt to process an extensive
      mount list. This occurs when the client is processing more
      than one file system simultaneously and there are several
      NetApp volumes. The issue should not occur while backing up a
      single file system.
    
      This issue is not specific to NetApp VFilers. It may occur on
      any NetApp filer.
    Tivoli Storage Manager Versions Affected:
      6.4 Clients
    Customer/L2 Diagnostics (If Applicable)
      When the race condition is encountered the following messages
      are seen in the dsmerror.log
      ANS3417W /nas-backup/vol/cit_dba_share: A system call
        psCollectMountTableInfo failed with code 6213 - NFS
        mount point for entity not found.
