ONTAPI volume-get-iter call fails to return some volume-id-attributes

Last Updated:

Applies to

  • ONTAP 9
  • Veeam
  • SnapVault


  • A backup job in Veeam is not deleting secondary storage snapshots because of a rescan job.
  • An issue with the ONTAPI volume-get-iter call found that it is sometimes not returning all the requested information, like the volume <uuid> tag under <volume-id-attributes>.
  • Volumes without the <uuid> tag are not correctly written into the Veeam database, and their snapshots are not cleaned up.
  • The following error is reported in the Veeam logs:

[08.07.2022 08:22:19] <01> Info     Response:

[08.07.2022 08:22:19] <01> Info         </next-tag><num-records>7</num-records></results>
[08.07.2022 08:22:19] <01> Error        Property 'volume-id-attributes/uuid' was not found (System.Exception)
