Hi,
Is it possible to use a single flash for all the switches in stack?
In one of my locations, I found four switches in stack. When I try to check the IOS for all the switches in stack, except in master, all other are not showing any output for sh flash:
If the master switch is down, how the other switches will run!!!
Here is the output of sh ver:

Hi
You should be able the do a sh flash2 and see the image version
If it's not there, the switch will continue working but will not boot if reseted
You must always have a valid image on every switch in the stack
Please rate helpful post

No each switch has its own image in its own flash , to look at it do the following.
show flash1: Switch 1
show flash2: Switch 2
show flash3: Switch 3
etc , etc , etc.............
