Applies to

  • ONTAP 9 and later
  • CIFS auditing enabled

Issue

  • MDV volume size increasing more than 2GB and consolidation job is not running on the node where MDV volume is located.
  • Due to this, CIFS auditing is not working and no further log destination file is being generating.
  • MDV volume full or nearly full alerts seen in ems logs:

  • One or more MDV volume size is more than 2GB:
