Cluster Snapmirror Lag


Sorry if this has been discussed before, but I wasn't able to find it.

I'm looking to find the lag time for snapmirrors on c-mode. In 7-mode, when we did Get-NaSnapmirror we could get LagTimeTS. So far I'm unable to find lag time for c-mode and I can't tell if I'm just blind or if it's not there. Has anyone else run into this?

Re: Cluster Snapmirror Lag


There isn't a LagTimeTS member for Get-NCSnapmirror as far as I could tell.  I've used LagTime to get the seconds since the last transfer and I've worked with that before. 

To find relationships older than a day: get-ncsnapmirror | Where-Object {$_.lagTime -gt 86400}

To change the output from seconds to date format I did the following:

get-ncsnapmirror | select SourceLocation,DestinationLocation,@{n="Lag";e={(get-date).addseconds(($_.LagTime * -1)).tostring('MM/dd/yyyy')}}

SourceLocation                                         DestinationLocation                                    Lag                                                
--------------                                         -------------------                                    ---

SRC:vol_homedirs                              DEST:vol_homedirs                                    09/15/2014                                         
SRC:vol_test                                         DEST:vol_test                                       01/29/2014
