Re: How do i enable an ifgrp in clustered mode

Was this ever resolved? I am having the same issue in my environment.

 

Thanks,

Re: How do i enable an ifgrp in clustered mode

Apologies for the late reply.

 

I raised a case with Netapp and was asked to collect some data running the following commands. The moment i ran step 13 below, which corresponds to the ports involved in the LACP itslef, my ifgrp was back online. We were running 8.3p4 at the time and Netapp put this down to a firmware issue with the CNA Qlogic cards on the controller. After upgrading the firmware, never experienced the problem again.

 

What version of firmware are you running?

 

Hope this is of some use.

Upload CNA firmware dump from

     /mroot/etc/log  ->  qla_<port>_*.dmp (FW dump)

Re: How do i enable an ifgrp in clustered mode

I had a similar issue with implementing NFS for VMWare on AFF300.

 

The root cause was traced to an incorrect vpc configuration on the switch. Due to a misslabeling of the switch ports, we were configuring vpc for ports belonging to separate NetApp nodes. This caused one physical port/node on NetApp be down.

 

networking group ran the following command:

show vpc consistency-parameters vpc # (ie 19), and realized that lag-id was not the same on (in our case one port per swtich).

 

on the netapp side, we ran the following command (two nodes in our environment): 

node run -node "nodename" cdpd show-neighbors 

node run -node "nodename" cdpd show-neighbors 

 

This provided us information showing where the 10 GB NetApp NFS designated ports were connecting to the Cisco Nexus switch. Once the right ports were configured for vpc, ifgrp was up an health, and both ports were healthy as well.

 

Hope this helps.
