SSD disk always showing as is-media-scrubbing=true

We are using the API in Nagios to query disk health and one of the states we query is "is-media-scrubbing".  We recently added an AFF8080 to our cluster which has 12 SSDs.  2 of the 12 SSDs are always showing as is-media-scrubbing=true.  I am unable to find this value via the CLI.  What does this true value mean?

 

This is the sprintf output for the disk queried from "storage-disk-get-iter".

Re: SSD disk always showing as is-media-scrubbing=true

Is the RAID group doing a media scrub?  Use the command "storage aggregate show-scrub-status" from the CLI (or PowerShell cmdlet "Get-NcAggrScrub").

Re: SSD disk always showing as is-media-scrubbing=true

I do not believe a scrub is running.  The API status is showing is-media-scrubbing=true since we installed the AFF8080, never seems to go to false.  Our FAS8040 never showed as true.  The AFF8080 was an addition to our FAS8040 cluster.

Re: SSD disk always showing as is-media-scrubbing=true

We are observing the same problem on two systems after an upgrade from 8.3.2P? to 9.1P11.

 

In our situation, after digging a little deeper into the problem, it looks like all spare disks on the cluster are having the <is-media-scrubbing> property set like this:

 

                    <disk-raid-info>

                                <active-node-name>stgb-pidpa-n01</active-node-name>

                                <container-type>spare</container-type>

                                <disk-shared-info>

                                </disk-shared-info>

                                <disk-spare-info>

                                        <is-media-scrubbing>true</is-media-scrubbing>

                                        <is-offline>false</is-offline>

                                </disk-spare-info>

                                <disk-uid>5002538A:07219DE0:00000000:00000000:00000000:00000000:00000000:00000000:00000000:00000000</disk-uid>

                        </disk-raid-info>

 

and some data disks are reporting media scrubbing like this:

 

                  <disk-raid-info>

                        </disk-raid-info>

 

Now, all those disks, in our situation, are ADP partitioned disks that have at least one partition that is not used and in fact uased as spare, eg.

All those disks are "scrubbing" even the disks in shelf 30 whose partition 2 is actively in use.

 

We have a case open with support (2007380388) to look a little deeper into this. I will report back as soon as something comes out of this.

 

Best regards!

Re: SSD disk always showing as is-media-scrubbing=true

Forgot to add, if you are using a Nagios plugin such as check_netapp_ontap.pl it will look specifically for this info:

 

if (defined($nahDisk->child_get("disk-raid-info")->child_get("disk-aggregate-info"))) {
$hshDiskInfo{$strDiskName}{'scrubbing'} = $nahDisk->child_get("disk-raid-info")->child_get("disk-aggregate-info")->child_get_string("is-media-scrubbing");

 

Because it is looking specifically under disk-aggregate-info, those disks will pop up as scrubbing when for instance spare disks where <is-media-scrubbing> is sitting under <disk-spare-info> and this Nagios plugin doesn't check this.
