Re: FAS2720 & AFF220 4 Node cluster

This is a standard setup issue. The ONLY ports that should be in that list (in other words, based on the output, in the Default Broadcast-Domain) are connected ports on the same physical network.

 

Different customers have different setups. With that, at a minimum, the broadcast-domain should include e0M from each node. *IF* you have e0c/e0d/e0e/e0f connected and are on the same physical network (whatever networ e0M is on, like 192.168.1.1 - 192.168.1.4) then it will work. If it is not, then it is entirely possible when the port fails (or the plug is pulled) it will go to another port and advertise there (Reverse ARP) that the IP address has moved.

 

I have seen this event transpire before and the cluster became unavailbel through the cluster_mgmt port.

 

Please correct your Broadcast-domain(s) and try again.

 

Typical Broadcast domains seperate things out. For example:

 

Default (MTU 1500):

node1:e0M

node2:e0M

node3:e0M

node4:e0M

 

NFS (MTU 900):

node1:a0a-101

node2:a0a-101

node3:a0a-101

node4:a0a-101

 

CIFS (MTU 1500):

node1:a0a-201

node2:a0a-201

node3:a0a-201

node4:a0a-201

 

Provide more detais if this does not work.

 

Suggestions include:

"broadcast-domain show ; ifgrp show"

Also

"net int show -failover"

 

(but please try to copy/paste if you can instead of a "picture". I know, some places cannot, but if you can, it is easier!
