Auto Image Copy for stack units

The Auto Image Copy feature ensures that all units in a stack are running the same flash image after a stack merge. This feature
also enables automatic reload of the stack units. It prevents the image mismatch that occurs when one or more member units
join the stack with a different running image and signature than the active controller and standby controller.
Auto Image Copy is enabled by default on devices, and the user does not have to manually copy the active controller's running
image to the mismatched members.
Auto Image Copy limitations
The following limitations apply to the Auto Image Copy feature:
• Auto Image Copy is applicable only to those stack units that are in a non-operational image mismatch state.
• Auto Image Copy does not work if there is a major image mismatch, when the image version of the IPC is different from
the stack unit version.
• Auto Image Copy does not work if the user has copied a different image into the flash, creating a mismatch in versions
between the flash and the running image on the active controller for the stack.
Verifying Auto Image Copy
Use the show stack command to check for any units in the mismatch state after the stack is formed. The following example
shows that stack unit 2 is not operational, due to an image mismatch.

Disabling Auto Image Copy
Auto Image Copy is enabled by default. However, if you wish to disable this feature, enter the following command in global
configuration mode.
device# configure terminal
device(config)# image-auto-copy disable
Use the no image-auto-copy disable command to re-enable Auto Image Copy. This restarts Auto Image Copy immediately and
ensures that all stack units have the same image.
NOTE
You can use the show running-config or the show stack detail command to see if Auto Image Copy is disabled.
