Continuing from the previous post and applying volume comments...

Function Apply-CmSnapPol can be used to apply snapshot policy to a volume, and returns true if successful and false if not.

FUNCTION Apply-CmSnapPol{

  Param([String]$SNAPPOL,[String]$VOLNAME,[String]$SVMNAME)

  $a = Get-NcVol -Template

  $q = Get-NcVol -Template

  Initialize-NcObjectProperty $a VolumeSnapshotAttributes

  Initialize-NcObjectProperty $q VolumeIdAttributes

  $a.VolumeSnapshotAttributes.SnapshotPolicy = $SNAPPOL

  $q.VolumeIdAttributes.Name = $VOLNAME

  $q.VolumeIdAttributes.OwningVserverName = $SVMNAME

  [Void](Update-NcVol -Query $q -Attributes $a)

  IF((Get-NcVol -Name $VOLNAME -Attributes $a).VolumeSnapshotAttributes.SnapshotPolicy -eq $SNAPPOL){ RETURN $TRUE }

  ELSE{ RETURN $FALSE }   

}

FUNCTION Check-ApplyCmSnapPol {

  Param([String]$SNAPPOL,[String]$VOLNAME,[String]$SVMNAME,[String]$LOGFILE)

  [Boolean]$Check = Apply-CmSnapPol $SNAPPOL $VOLNAME $SVMNAME

  IF($Check){ Wr ("Applied snapshot policy $SNAPPOL to volume $VOLNAME") GREEN; Wr }

  ELSE{ Wr ("FAILED to apply snapshot policy $SNAPPOL to volume $VOLNAME") RED -Log $LOGFILE; Wr }

  If($ToDisplay){ Write-Host $ToDisplay -ForegroundColor $Color -NoNewLine } else { Write-Host }

  If($LogFile){ $ToDisplay >> $LogFile }

}
