How to create a Snapshot Policy

AllenChang — Wed, 04 Jun 2025 09:49:36 GMT

I use new-ncsnapshopolicy command to create a snapshot policy,

it appear a error,and told me need svm parameter

PS C:\File> New-NcSnapshotPolicy -Name mysspolicy1 -Schedule sm1min -Count 60 -SnapmirrorLabel 1min
New-NcSnapshotPolicy : Svm parameter neither specified nor set
位於線路:1 字元:1
+ New-NcSnapshotPolicy -Name mysspolicy1 -Schedule sm1min -Count 60 -Sn ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [New-NcSnapshotPolicy], ArgumentException
+ FullyQualifiedErrorId : Svm is empty,DataONTAP.C.PowerShell.SDK.Cmdlets.Snapshot.NewNcSnapshotPolicy

But when I add -Svm parameter,
It still error

PS C:\File> New-NcSnapshotPolicy -Name mysspolicy1 -Schedule sm1min -Count 60 -SnapmirrorLabel 1min -Svm svm1
New-NcSnapshotPolicy : 無法繫結 'Svm' 參數。無法將類型 "System.String" 的 "svm1" 值轉換為類型 "DataONTAP.C.Types.Snapshot.Svm"。

+ ... ysspolicy1 -Schedule sm1min -Count 60 -SnapmirrorLabel 1min -Svm svm1
+ ~~~~
+ CategoryInfo : InvalidArgument: (:) [New-NcSnapshotPolicy]，ParameterBindingException
+ FullyQualifiedErrorId : CannotConvertArgumentNoMessage,DataONTAP.C.PowerShell.SDK.Cmdlets.Snapshot.NewNcSnapshotPolicy

How can I fix this problem ?

I haven't used these 'new-nc*' commands, so don't knw how it works. Can you check - Which context are you connected to : Cluster?

Try connecting to SVM context and then run those commands.

PS C:\> Connect-NcController -Name <SVM_Mgmt_IP>

Note: make sure 'vsadmin' account is unlocked for the given SVM.

Hi Ontapforrum

ok.

Try connecting to SVM context and then run those commands.

PS C:\> Connect-NcController -Name <SVM_Mgmt_IP>

Let us know if it works, or you get different error?
