Copying Bootable Images between Flash Memory Cards
Copying Bootable Images between Flash Memory Cards
As future releases of Cisco IOS images become available, you will receive these images either as a
file booted from a network server, a file on floppy disk, or a file on a Flash Disk or Flash memory
card.
The procedure for copying bootable images between Flash memory cards and between Flash Disks
is similar; however, this section is specific to Flash memory cards.
Note For procedures that explain how to copy a bootable images between Flash Disks, refer to the
Using the Flash Disk document that accompanies every Flash Disk shipped from the factory.
The following scenario describes how to use a newly released image on a Flash memory card in a
system that has an older image on a Flash memory card in slot 0 and a default boot image in the
onboard Flash SIMM.
For this scenario, the filenames are as follows:
• The new image on the new Flash memory card is new.image.
• The old image on the Flash memory card in slot 0 is old.image.
• The bootable image in onboard Flash memory is boot.image.
You will copy the new image from the new Flash memory card onto the Flash memory card that
contains the old image.
Note The scenario assumes that the new image will fit on the Flash memory card in slot 0,
alongside the old image. If there is not enough available space, use the delete command to delete
files from the Flash memory card to make sufficient room for the new image; however, do not delete
the image.old file. Then use the squeeze command to remove these deleted files from the Flash
memory card. If, after you have deleted files and used the squeeze command, the two files cannot
coexist on the Flash memory card in slot 0, remove this card (place it in an antistatic bag and store
it in a safe place), then insert the new Flash memory card (with the file new.image) in slot 0. Proceed
to Step 5 and use the command boot system flash slot0:new.image to designate the file new.image
as the default boot image.
Step 1 Boot the router. By default, the file boot.image is used.
Step 2 Enable the router as follows:
Router> en
Password:
Router#
Step 3 Insert the new Flash memory card in slot 1.
Step 4 Use the following command to copy the file new.image in slot 1 to the Flash memory card
in slot 0, only if there is enough memory space for the two images to coexist. If there is
not enough memory space, proceed to Step 5.
Router# copy slot1:new.image slot0:new.image
Note You can also enter the preceding command as copy slot1:new.image slot0:.
