Product and Software: This article applies to all Aruba controllers.
Several reasons could prevent a controller from booting to a point where a user cannot log into the CLI:
- A corrupted startup configuration is uploaded and attempted to be booted. Search the KB for the procedure to boot from a dummy configuration file to try to recover from this error.
- When the file system is full, the ArubaOS may not fully load to a point that will allow a user to login.
- Hardware damage.
The flash can be recovered by formatting the entire file system, but the recovery process would require the restore of the ArubaOS that will delay the recovery process. For accidental upload of a corrupt configuration file, search the KB for the procedure to boot from a dummy configuration file.
The recovery process can be abbreviated by just formatting the partition where the file-system is full or damage. Partition 0:0 and 0:1 is where the two ArubaOS is stored. Partition 0:2 contains the full file system or a corrupted configuration file.
To try to recover the controller, follow these steps:
1) Power cycle the controller and break into the CPBoot by hitting the enter key on startup (console access).

2) Format Partition 0:2, which is where the configuration file is stored.
cpboot> format 0:2
Format will erase everything on the internal flash's partition 2.

3) Reload the controller and follow the start-up wizard to regain IP connectivity to the controller.
4) Restore the last offline flash backup and reload the unit.
5) Verify the images in the two partitions by issuing the following command:
