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. 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.
