WFA 4.2 / CDOT Pack 1.5.0 - Issue with tiering policy in modify volume command

MartinRohrbach — Wed, 04 Jun 2025 13:33:25 GMT

After upgrading to the latest "WFA pack for managing Clustered Data ONTAP" 1.5.0, we have issues with the "Modify Volume" command.

In the latest version, it takes a new parameter as such:

 [parameter(Mandatory=$false, HelpMessage="The tiering policy that is to be associated with the volume.")]
 [ValidateSet("auto","none","backup","snapshot-only")]
 [string]$TieringPolicy,

This parameter is mapped to Volume.tiering_policy.

However, a newly created volume using "Create volume" without a defined tiering policy will default to "snapshot_only", note the underscore, this is the part from the reservation:

        IF('${TieringPolicy}' IS NULL,
        "snapshot_only",
        '${TieringPolicy}'),

This "snapshot_only" will then not be accepted by the "Modify Volume", because it only takes "snapshot-only" with a dash rather than an underscore.

@netapp: can you confirm that and/or is this a known bug and in the works or does that need a ticket?

Hi Martin,

The upcoming release name from ONTAP is DayBlazer (9.5.0).

This issue will be fixed in CDOT 9.5.0 pack.

Note:

Since, CDOT pack aligned with ONTAP release, the next CDOT pack version will be 9.5.0
