Broadcast domain bug: how to fix ?

Greg_Wilson — Mon, 26 Jul 2021 00:26:58 GMT

I have this bug on a 2750 running 9.9.1

https://mysupport.netapp.com/site/bugs-online/product/ONTAP/BURT/1378530

"error: details not available" status as part of the "broadcast-domain show"

but I get an error when I try to remove ports as it is the "Cluster" Broadcast Domain ?

Any ideas how to fix it then ?

Hi Greg,

Have you performed an ARL headswap to this controller previously? That is a prequisite for that BURT.

In some cases, per https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/%22network_port_broadcast-domain_show%22_reports_%22error%3A_details_not_available%22_for_some_ports just changing the MTU back to 9000 will be sufficient.

Let us know how it goes!

Hi,

This is a brand new 2750 install with 72 1.8TB SAS drives.

It shipped with 9.8P3 and I upgraded that to 9.9.1

Never performed an ARL headswap

I did try to remove the ports but it complained there were LIFS on them.

I might just wait 9.9.1P1 and see if that fixes it. I don't think there is an issue.

Have you tried to change the MTU as I suggested?

like Alex suggested, modifying the broadcast domain may fix it.

Network port broadcast-domain show" reports error: details not available for some ports

Hello @Greg_Wilson ,

Were you able to fix the issue?

No I have no fixed it and its getting more annoying.

The only thing you can do is make sure its the first thing you delete/fix-up after you setup a new cluster

Don't make any LIFs until you have sorted it out, otherwise you need to delete them all.

Sorry.. I have not had a chance to look at this as we needed to start the migrations ASAP and I was not keen to play around with this as the cluster is working. I see there is also 9.9.1P1 which I plan to install ASAP when we get some free time between migrations.
