I have done a hostname change on 2 of my 48k's, and FabricWatch is still sending emails with the old hostname in the From address. FOS is 6.1.0h.
verify is the "switchname" and "chassisname" corret set.
A few years ago, I met same issue in a boxtype silkworm.
At that time, I need to reboot the switch.
Could you try to hafailover?
Rebooting the switch is what I was thinking. I was really hoping not to have to do that though.
