Append additional property to existing cifs share using Powershell

[bsnyder27]

Given whatever change occurred between us running 8.3 and now being at Ontap 9.1, we need to add the show_previous_versions property to a number of cifs shares to give users VSS functionality back.

Anyone know how to append instead of replace the properties using the Set-NcCifsShare cmdlet for a given cifs share?

Start with this one

 Set-NcCifsShare

I should have added a little more detail.

Most shares are with the default settings.

How many shares are outside of the following default settings

oplocks, browsable, changenotify, show_previous_versions

You can just push all these settings back down by doing a get | set

If you have different requirements, you can do stuff like

$share = (get-nccifsshare -VserverContext vservername -ShareName data$).shareproperties -join ","

That's your current properties of the share,

Then you can adjust $share each time and re-write it each time.  Fairly simple

I did it like this using a foreach loop, to keep the current set of share properties and just append the "show_previous_versions" property:

$results = @()

Connect-NcController -Name $controller -Credential $creds -Verbose

$shares = Get-NcCifsShare -CifsServer $cifsserver

$results = $shares|? Path -like "*path_string_here*"|? ShareProperties -NotContains "show_previous_versions"

foreach ($result in $results)
     {$change_array = @()
     $change_array = $result.shareproperties + "show_previous_versions"
     Set-NcCifsShare -Name $result.ShareName -ShareProperties $change_array -VS vserver_name_here}

Didn't think about using -join "," but that works really well too.

Edit: Also, I filtered on a group of CIFS shares that shared a common string in the path that I knew I wanted to isolate, which is why I used the Where-Object -like "*path_string_here*", but you could leave that off and then echo out $results to see what paths do not have "show_previous_versions."  You can also add the -whatif parameter to Set-NcCifsShare to see what would be changed before making the change.
