Troubleshooting image copy issues
The copy tftp flash command copies the image to all stack units including the active controller. The
copy flash flash command copies the image from the primary or secondary flash on the active
controller to the primary or secondary flash image of a stack member, respectively. If you are unable
to copy an image to one or more stack units, check the following:
• Make sure the unit is actually part of the stack. Use the show stack command.
• If a unit joins a stack after the image copy command was issued, you will need to copy the image
to this unit separately.
Stack mismatches
When a stack mismatch occurs, the active controller can put any stack member into a non-operational
state, which disables all of the ports except the stacking ports. Stack mismatches can occur for a
variety of reasons, which are discussed in this section.
NOTE
The active controller can still download an image to the non-operational unit.
The active controller generates a log message whenever it puts a stack unit into a non-operational
state. The following examples describe the types of mismatches and the related log message:
• Advanced feature mismatch - The active controller is enabled for advanced features (such as
BGP) and the stack unit is not enabled.
Stack: Unit 2 0000.0020.0100 doesn’t have the matching advanced feature privileges
• Image mismatch - A stack unit is running a different software image than that of the active
controller.
Stack: Unit 2 0000.0020.0100 image mismatch
• Configuration mismatch - The module configuration for a stack unit does not match the
reserved configuration on the active controller.
Stack: Unit 2 0000.0020.0100 config mismatch
• Memory allocation mismatch - The active controller does not have enough memory to
accommodate the stack unit.
Stack: Malloc failure for unit 2.0000.0020.0100
These mismatches are described in the following sections.
