Does anyone have an example of using the NetApp.ONTAP PowerShell templates for requesting specific attributes? I know it’s possible with the raw/direct #1063542514780475493 using ?fields=name. I need the name of all snapshots for a volume, but nothing else. And all the other stuff tends to be expensive/time consuming. One volume of about 10 snaps took 8min to return.

I've been using it basically like this:

foreach ($lif in $lifs) {
  $q = Get-NcNetInterface -template:$true 
  $q.InterfaceName = $lif.InterfaceName
  $q.Vserver = $lif.Vserver
  $a = Get-NcNetInterface -template:$true
  $a.AdministrativeStatus = "down"
  Update-NcNetInterface -Controller $Controller -Query $q -Attributes $a -ZapiCall:$true | Out-Null
}

I don't know if requesting certain attributes (like in ZAPI/REST) is possible with PowerShell templates

Both of those seem to be acting as filters.

That's unfortunate

the first ($q) is the query, so yes, that's a filter. The second ($a) sets the attributes. I don't remember why I had to do it this way, but it wouldn't work otherwise for some weird reason 🙂

Apparently there's a command Invoke-NcSystemApi but it speaks XML which implies ONTAPI/ZAPI only. I found this provides what I need:

PS /> $snapshots = (Invoke-NcCli -Command "snapshot show" -Query '{"volume": "test_vol"}' -Fields "snapshot").value
PS /> $snapshots.Count
13
PS /> $snapshots[0]
{
  "vserver": "test_svm",
  "volume": "test_vol",
  "snapshot": "test_vol_31"
}
PS />
