We have an IBM H Chassis with two IBM 10gig switches inserted in the back. These switches are stacked and are running an older version of firmware. We would like to upgrade these switches in a non-disruptive fashion. In other words, upgrade one switch, let it reboot, and then upgrade the second switch and let it reboot. Is this possible?
Our entire vSphere server and VMWare View environment lives on the 6 blades in this chassis. If I cannot upgrade the two switches independently I need to bring down the entire environment, upgrade the switches, and then bring it all back up. This is a lot of work and a big disruption I am hoping to avoid.
