Troubleshoot software image expansion failure due to lack of bootflash space
Problem
When using the controller-mode enable command on a device to change to Controller mode, the command output indicates that there is insufficient space on the bootflash to expand the software file.
Conditions
This scenario can occur when changing a device to Controller mode in releases earlier than:
-
Cisco IOS XE Catalyst SD-WAN Release 17.12.5a
-
Cisco IOS XE Catalyst SD-WAN Release 17.15.2
-
Cisco IOS XE Catalyst SD-WAN Release 17.16.1a
Possible causes
If the bootflash is storing previous software image files or other data requiring significant space, there may not be enough room to expand the latest software image .bin file.
Possible solutions
Step 1 | Use these steps to determine whether the device has successfully expanded the software image file. |
Step 2 | If the device was not successful, follow these steps.
|
Step 3 | If the device does not successfully expand the software image file after you have freed up space on the bootflash, contact Cisco support for assistance. |
