We recommend that you use the format flash command to reformat the ACE
Flash memory only under the guidance and supervision of Cisco Technical
Assistance Center (TAC).
The ACE uses the third extended file system (ext3) as the base file system. The
file system is used to allocate and organize storage space for various types of
storage, such as startup-configuration files, SSL certificate storage, core files,
image storage, and log files.
To erase all data on the Flash memory and reformat it with the ext3 base file
system, use the format flash: command. All user-defined configuration
information is erased.
The ACE performs the following verification sequence prior to reformatting Flash
memory:
If the system image (the current loaded image) is present in the GNU GRand
•
Unified Bootloader (GRUB) boot loader, the ACE automatically performs a
backup of that image and then performs the reformat of Flash memory.
If the system image is not present in the Grub boot loader, the ACE prompts
•
you for the location of an available image to backup prior to reformatting the
Flash memory.
If you choose not to backup an available image file, the ACE searches for the
•
ACE-APPLIANCE-RECOVERY-IMAGE.bin image in the Grub partition of
Flash memory. ACE-APPLIANCE-RECOVERY-IMAGE.bin is the recovery
software image that the ACE uses if the disk partition in Flash memory is
corrupted.
If ACE-APPLIANCE-RECOVERY-IMAGE.bin is present, the ACE
–
continues with the Flash memory reformat. The CLI prompt changes to
"switch(RECOVERY-IMAGE)/Admin#" as a means for you to copy the
regular ACE software image.
