Unified Switch software supports a dual image feature that allows the switch to have two software images in the permanent
storage. You can specify which image is the active image to be loaded in subsequent reboots. This feature allows reduced
down-time when you upgrade or downgrade the software.
delete
This command deletes the supplied image file from the permanent storage. The image to be deleted must be a backup
image. If this image is the active image, or if this image is activated, an error message displays.
