Get-NaSnapMirror (7 mode) and Get-NcSnapMirror (cDOT Cluster Mode)

Hello

Can someone please help with the following question.

We have a number of script using the NetApp PowerShell toolkit cmdlets which we have been using against 7 mode filers.

We are now upgrading to cDOT filers and I notice there is a lot of difference betweent the properties return via the above two command for example

if I do a Get-NaSnapMirror against a 7 mode volume it returns (I have change the names below for security)

Source : bovErnie:ATOntdata
Destination : whyErnie:ATOntdata
BaseSnapshot : whyErnie(1918096640)_ATOntdata.875
Contents : -
CurrentTransferError :
CurrentTransferType :

LastTransferDuration : 65
LastTransferDurationTS : 00:01:05
LastTransferFrom : -
LastTransferSize : 21528576
LastTransferType : -
MirrorTimestamp : 1437609603

ReplicationOps :
SourceLocation : bovErnie:ATOntdata
State : source
Status : idle
TransferProgress : 0

ReplicationOpsSpecified : False

If I run the same command against a cDOT vServer I get

NewestSnapshot=snapmirror.14d7295f-e4f7-11e4-9872-00a0985e53ea_3_2147484673.2015-07-23_142500

Now the thing is I want to take our 7 mode scripts and convert to work with cDOT with the minium of pain.

for example a colleague wrote the following lines of code for a 7 mode script

$Output = Get-NcSnapmirror -Controller $SourceController

foreach ($Vol in $OUTPUT)
{
$Source = $Vol.SourceLocation
$Destination = $Vol.DestinationLocation;
$BaseSnapshot = $Vol.BaseSnapshot;
$Contents = $Vol.Contents;
$CurrentTransferError = $Vol.CurrentTransferError;
$CurrentTransferType = $Vol.CurrentTransferType;
$DestinationLocation = $Vol.DestinationLocation;
$LagTime = $Vol.LagTime;
$LagTimeTS = $Vol.LagTimeTS;
$LastTransferDuration = $Vol.LastTransferDuration;
$LastTransferDurationTS = $Vol.LastTransferDurationTS;
$LastTransferFrom = $Vol.LastTransferFrom;
$LastTransferSize = $Vol.LastTransferSize;
$LastTransferType = $Vol.LastTransferType;
$MirrorTimestamp = $Vol.MirrorTimestamp;
$MirrorTimestampDT = $Vol.MirrorTimestampDT;
$SourceLocation = $Vol.SourceLocation;
$State = $Vol.State;
$Status = $Vol.Status;
$TransferProgress = $Vol.TransferProgress;
}

A lot of the above properties e.g. TransferProgress in the 7 mode output are not there by default on the cDOT output

Question.

Is there any easy way (e.g. using an alternative cmdlet) or has someone already written a function to give me the same out put I was getting in 7 mode so I do not have to adjust all my scripts?

Thanks

Ernie

What version of cDOT are you using..

Pipe your get-ncsnapmirror | gm and paste the results.. You should be seeing more

But I do agree, it appears we need to make the some conversions of the date objects, there is no friendly field, it appears..

Thanks very much for the reply.

It looks like the TransferProgress property is now available on objects returned by Get-NcSnapMirrorDestination therefore I will use this instead.

Thanks again
