I had updated the IOS on the new switch before adding it to the stack this weekend. After adding it to the stack, I looked at the stack and noticed that the new switch had a version mismatch. To "fix" this, I deleted the IOS folder in flash on the new switch, and then I copied the IOS file from switch 1 to switch 6. This resolved the "version mismatch" error. I reloaded switch 6 through cli and it took forever to come up (actually I had to disconnect from power). I then decided this morning to connect my console cable to that switch and reload through cli again. I noticed that the switch is trying to load the old IOS (the one that was mismatched with the stack) and then it fails over to the good IOS. How can I stop this from happening?
