Powershell: How change the tiering-policy for a volume?

Northman — Tue, 31 Oct 2023 15:16:19 GMT

I am running ONTAP 9.11P8 .I have tried various commands, but I have had no luck with:

Update-Ncvol

Set-Ncvol

Set-Ncvoloption

I also consulted Google Bard (claiming it is updated to 9.11P8), which suggests:

# Import the NetApp ONTAP PowerShell module
Import-Module NetApp.Ontap.PowerShell

# Rename the volume
Set-NcVol -Name myvolume1 -NewName myvolume

# Get the current tiering policy
$tieringPolicy = Get-NcVol -Name myvolume | Select-Object -ExpandProperty TieringPolicy

# Set the new tiering policy
$tieringPolicy = "all"

# Update the volume with the new tiering policy
Set-NcVol -Name myvolume -TieringPolicy $tieringPolicy

But I keep getting the error: "Select-Object: Property "TieringPolicy" cannot be found"

Omitting the pipe to "Select-Object -ExpandProperty TieringPolicy" works:

i.e

$tieringPolicy = Get-NcVol -Name myvolume

Is this simply not supported in powershell for 9.11P8? Do I have to look into REST API calls?

Is it safe to say you have the volume on a FabricPoll Aggr already? Does it already have a tiering policy?

hi, yes, it is a test volume, though. I can see it has the snapshot policy right now. It is in a aggregate that is setup with a FabricPool.

Hi,

as far as I know there is only a command to get you the information about the tiering policy.

"Get-NcVolumeTieringPolicies"

The only two ways I can think of is via the Powershell Invoke SSH-Function or you can always go with the REST API POST (which I would recommend)

Best regards

I understand this is an old question, and I came across it while searching for how to set the tiering policy for a new fsx instance. There is another way to get the status in powershell using the

VolumeCompAggrAttributes on any given volume.

PS C:\> (get-ncvol vol_1).VolumeCompAggrAttributes NcController TieringPolicy ------------ ------------- xxxxxxxxxxxx all

You can set the tiering policy at volume creation in powershell using new-ncvol option of -TieringPolicy <string>. And you can update the policy using update-nvcol

update-ncvol -query @{name="$vol"} -Attributes @{VolumeCompAggrAttributes=@{TieringPolicy="all"}}

A good thing to note is how update-nvol allows you to update any attribute/setting versus what is limited in set-ncvol.

Good Luck
