Enabling NIC Teaming while servers in production - OK?
Posted on 2013-10-30
I recently discovered one of my clients had their main ESXi host plugged into a 10/100 switch. I moved it to a gig switch and things are happy happy now. (ESXi 5.1)
I have 3 additional NICS on the server I'd like to enable NIC teaming with. I have cabled the other 3 nics and plan on using the default NIC Teaming settings:
Load balancing: checked - route based on originating virtual port ID
Network fail over detection: not checked
Notify switches: checked - Yes
Fallback: checked - Yes
Override vswitch failover order: checked.
Move the 3 unused adapters into the active adapters group and apply.
My question is this: Can this be done w/o having to shutdown guests? It is VERY difficult to schedule downtime and if I can do this during business hours, that would be ideal.
I've read that I have to reboot the individual VM's to get them to 'load balance' themselves. It will be much easier to schedule individual reboots rather than their entire network.
Only 1 vSwitch, flat network (no vlans).
