Netapp Aggregate Snapshot Reserve Full Warnings - spam to me

Is there a way I can tell the Netapp file to not send alerts on aggregate snapshot reserve full?  It is not actionable and just an inbox filler as far as I can tell.  Thanks!

    Assisted Solution

    This is your Operations Manager/Data Fabric Manager Server stating that your snapshot reserve is full

    You should look at it since snapshot can write into usable storage once they go beyond snapreserve since the snap reserve is only used for accounting.  

    I am not sure you can disable the alarm in DFM but what I typically do is change the schedule for the snapshot on the aggregate which lowers the snap reserve.

    Our typical configuration is to change the shapshot schedule to every 2 hours and keep for 2 days.  This way if a reallocate gets corrupt or issues with the aggr you can get back to operational a lot faster.

    Accepted Solution

    On your DFM server, enter these commands:

    dfm eventtype modify -v Normal aggregate-snapshot-reserve-full
    dfm eventtype modify -v Normal aggregate-snapshot-reserve-almost-full  

    This will disable these warnings
