Image mismatches
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 that of the master and standby units.
Auto Image Copy is enabled by default on Brocade devices and the user does not have to manually
copy the master’s running image to the mismatched members.
This feature is available on the following Brocade devices:
• Brocade FCX Series (FCX) Stackable Switch
• Brocade ICX 6610 Series (ICX 6610) Stackable Switch
• Brocade ICX 6430 Series (ICX 6430) Stackable Switch
• Brocade ICX 6450 Series (ICX 6450) Stackable Switch
NOTE
To manually copy the master image to the stack units, refer to “Copying the flash image to a stack
unit from the Active Controller” on page 283 and “Reloading a stack unit” on page 283 for more
information.
