How to upgrade the boot image on the 7200 and uBR 7200 series router
To upgrade the boot image in a Cisco 7200 or uBR 7200 series router, perform these steps:
Copy the new file into bootflash.
If the image is too large to load into the Flash SIMM, you will receive the messages shown in this example:
Router #copy tftp bootflash:
Address or name of remote host ? ....
Source filename ? c7200-boot-mz.120-5.XE2
Destination filename [c7200-boot-mz.120-5.XE2]?
Accessing tftp:c7200-boot-mz.120-5.XE2... Loading c7200-boot-mz.120-5.XE2
from 22.214.171.124 (via Ethernet4/0): !
%Error copying tftp:c7200-boot-mz.120-5.XE2 (Not enough space on device)
Crashinfo cannot write because it does not have memory.
The router tries to write as much as possible in the free space and then terminate with a write failure error message. Nothing happens to other files already in the Flash SIMM.
In a Cisco 7200 series router, this issue might appear even if there is no other file in the bootflash, since there are some oversized Cisco 7200 and uBR 7200 boot images.
