Hello @mark_schuren,
Certain fields in the output object from PSTK are not returned by ZAPI, but rather created by PSTK to make life easier for us as users. Created is one of those fields. When PSTK receives a ZAPI response which includes the "AccessTime" property it calculates/creates and populates the properties "Created" and "AccessTimeDT" (and of course "AccessTime") in the object returned.
We can determine this using the Get-Member cmdlet for the snapshot object:
PS C:\Users\asull> Get-NcSnapshot -Template | Get-Member
TypeName: DataONTAP.C.Types.Snapshot.SnapshotInfo
Name MemberType Definition
---- ---------- ----------

The easiest way to get what you're asking for is to simply specify both the SnapmirrorLabel and AccessTime properties...
Get-NcVol $volume | Get-NcSnapshot -SnapName $snapshot -Attributes @{ AccessTime = ""; SnapmirrorLabel = "" } | Format-ListYou could also use template objects if desired...
$template = Get-NcSnapshot -Template
$template.AccessTime = ""
$template.SnapmirrorLabel = ""
Get-NcVol $volume | Get-NcSnapshot -SnapName $snapshot -Attributes $template | Format-List
Finally, it's imperfect, but you can attempt to specify that all fields should be returned using this bit of script:
$template = Get-NcSnapshot -Template
$template.psobject.Properties | ?{ $_.IsGettable -eq $true -and $_.IsSettable -eq $true } | %{
$property = $_.Name
try {
$template.($property) = $true
} catch {
$template.($property) = $null
}
}
Get-NcVol $volume | Get-NcSnapshot -SnapName $snapshot -Attributes $template | Format-ListNote that it simply guesses as to an acceptable value for the property in order to force it to be returned by PSTK.
Hope that helps.
