Disable snapshot on netapp C mdoe volume using powershell commands

[CAPATEL_NET1984]

I was looking for command to disable snapshot on a volume but not able to find an option in netapp PS toolkit.

is there a command or options in cmdlet i can set to disable the snapshots on a particular vol?

Hello @CAPATEL_NET1984,

There are two ways you can disable snapshots:

1. Set the snapshot policy to "none"
2. Set the volume option "nosnap" to "on"

To change the policy, you can use this PowerShell:

Update-NcVol -Query @{ Name = $volName } -Attributes @{ VolumeSnapshotAttributes = @{ SnapshotPolicy = "none" } }

To disable the volume option:

Get-NcVol $volName | Set-NcVolOption -Key nosnap -Value on

You can read more about PSTK + snapshots here and volumes here.

Hope that helps!

taht query of setting it to none worked, but when i chnage the snapshot policy directly to none in create volume command's inputs in wfa it does not work

so I can use another powershell command to set none as SS policy on a volume but i can not use the wfa create volume certified command's in put name snapshot policy and can not set as nonw

also I ahve differnt code version in lab and prod and i noticed that on older code version 9.1p1 i need to do below, added -FlexGroupVolume:$false and it worekd fine

i did not added this on 9.2 version and it still worked

Update-NcVol -Query @{ Name = $VolumeName } -Attributes @{ VolumeSnapshotAttributes = @{ SnapshotPolicy = "none" } } -FlexGroupVolume:$false

Take a look at get-ncvol and update-ncvol.  I think the volume attribute you want to update is .NoSnap.  This could also be the option to enable user access to teh snapshot directory, so you will want to test this.  Look at the Example at the end of

get-Help Update-NcVol -full   for an example of how to do this.
