I broke a 7450 stack

We had a stack set up with a 7650 and 5 7450s.  There's an issue with the primary and secondary flash on one of the 7450s and, in trying to fix it, I rebooted the stack.  Now, the last two switches have been dropped from the stack and I would like some help getting them back.

Hey Clayton,

-You need to check if the images on the missing units are intact by  consoling to it.  Make sure it is same image version.  Also try to recopy the files that was corrupted on the unit 24.
-Also you can check if the SPX  Stack ports are up. (show spx connections)
-Check log files for any information as to why it fell off the stack.

I think it would be a good idea to open up a ticket as it might be a bit more complex.

Thanks.  When I console to the #24 switch, I get a "ICX7450-Boot>" prompt and I couldn't see which commands to use to access the flash memory.

Also, I thought one of the selling points of a stack configuration was that you could add a new switch, cable it up and issue one command to add it to the stack.  Don't I just need that command to re-add these two switches to the stack?

Hey Clayton,

We need to debug this further, it is stuck in boot monitor.

Best thing is to open a case and work with TAC.
