Hi,

For consistency check ONTAP cluster and switches use CONFIGADVISOR. For reference/compliance version table see support site.

ONTAP 9.7P2 does limit support CN1610 switches (from 9.6 actualy) Your CN1610 should be 1.3.0.2 with rcf 1.2

Met vriendelijke groet / Kind regards,

My mistake 😉 Here is my output just for reference…. I think it’s a pretty old software I have on the switches 😉

Should be

system cluster-switch show-all

The command you had is for the FC switch for things like flex array (attached storage through a FC switch)

I’d like some others to try this:

If you have a switched cluster run this command and record version of ontap you have and the time it takes to complete (it may take a few moments-minutes)

system cluster-switch show

Then run this command and note the time (which should be instant or near instant)

I want to open a bug on this but need more details like when / which release this actually stopped responding quickly.

In your case, it is able to read the switch name - in my case, it's not (name is just "-"). So maybe this is is also the reason for the message, because CDP was disabled in the first place.

I think what I'm looking for here is a way to "restart" this CSM daemon or to restart the validation/detection process, if that's possible at all.

OK, mine looks like this... and as you can see two nodes are connected to the same switches...

So I get this error... 6/17/2020 14:10:40 DK01NETAPP01-03 ERROR csm.mismatchRemoteDevice: CSM connection between source LIF 1001 and destination address 169.254.48.70 might not be optimal for session 0a05a7bb5da3abb3. The source is currently connected to nasw02 remote device and the destination is currently connected to nasw01 remote device.

(I get other such messages... so I assumed it was because of the cabling)

Maybe it's the switch config? I sadly does not have any remote management to my switches.....

I'm on ONTAP 9.7P2 so pretty new version...

Hi there

I have the same messages in my 4-node cluster. I believe it's because of the cluster cabling isn't correct (in my case anyway) we have two interconnected cluster switches, I think it's because we hooked up two cluster ports to the same switch.... We are in the process of migrating to a new cluster pair, so we don't want to investigate it further because the clustering works __ But I would suggest to check that you have one cluster cable from each host in each of your cluster switches...

Hi,

I have pages of those on a newly expanded cluster (was 6 nodes, now 10 for a tech refresh). CDP is enabled all over, and “net device-discovery show” shows good data. Currently 9.5P12.

I do have one of the ports down (bad cable, RMA taking 4+ days) so perhaps that is why? — Jason
