we testing upgrade logical chassis with 2 x VDX 6740, and we use coldboot from 7.0.2b to 7.1.0b3 version. Upgrade was successful but both VDX6740 they were automatically rebooted. It is normally ? Because I think automatically restarting two switches at once it isnt good idea because were interrupted all services on both VDX. Is there a way to use coldboot without restarting the switch or using a gradual reboot without interrupting all services on the VDX chassis?
