MTU setting between one our FAS3210 fires and its HA partner don't match. One filer has MTU defined in the /etc/hosts file, the other filer does not. Wondering if removing the defined entry to mimic the HA partner is a disruptive procedure or will the system accommodate that change without disruption.
Sorry, this is an HA pair. One doesn't have it defined in the rc file and is at 1500. The partner does have it statically set and it is at 1500. This became an issue when I ran an upgrade advisor and it was pointed out that the rc files don't match.
The reason I was asking b/c I wanted to make sure there were no jumbo frames.. Also you didn't mention you were doing an upgrade
It really doesn't matter technically b/c by default if you don't have MTU size it defaults to 1500, but for consistency, i would recommend removing it out of the RC file and then when you perform the upgrade you will have to do a takeover/giveback on each node and it will enter the running config.
