I have 6 ICX 6450 in a stack. 3 on one floor and 3 on another floor. We're no longer leasing 1 of the floors and therefore consolidating everything. The 3 switches that need to be moved are acting as the active and standby switches with all others being members. What would be the best way to move these switches?
Should I make one of the switches NOT being moved the active switch and reload the stack before unplugging those switches to be moved? Or can I just unplug them and move them without doing anything? Not sure what happens to the stack when it loses both active and standby switches.
Any help will be greatly appreciated.
Certainly, if you remove switches that are NOT the master or standby hitless-failover should allow just the moved switches to restart.
That said, I do not know if it will be a simple re-election for a master change or if that will result in a stack reload. You would probably need three (3) or four (4) of those to build a stack and test.
From the sounds of it, you may need to do some stacking gymnastics and musical switches in that the definition merely says:
Hitless stacking failover provides automatic failover from the active controller to the standby controller without resetting any of the units in the stack and with sub-second or no packet loss to hitless stacking-supported services and protocols.
That would lead me to think you would have to do some numbering, so a desirable standby is elected first THEN failover from the active controller to that standby... and then change to another standby and wait for the re-election to finish.
This is the kind of stuff where I just build a lab or schedule downtime if I cannot be bothered. It is also the type of stuff I do not guarantee will not cause an outage to management.
