Components Used The information in this document is based on the Cisco 5500 Adaptive Security Appliance (ASA) with software version 7.x. The information in this document was created from the devices in http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/81884-asa5500-disk0-error.html a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

The FW are configured in a A/S setup, and we ran into a bug that required us to upgrade the code. Problem was, one of the ASAs in the pair didn't even let me get to the disk0 via #dr while the other ASA constantly error opening failed to upload the image via FTP. FW01/pri/act# dir Directory of disk0:/ %Error opening disk0:/ (Too many open files) 8238202880 bytes total (4793798656 bytes free) Googling around I found a few articles stating that the flash of the ASA could of gone bad and one could try to reformat the flash. http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/113266-asa-flash-error-ts.html Not a good look when the ASA is in ANOTHER country in a datacenter with NO ONE around! Trying error opening disk0 other commands to get to the flash/disk resulted in similar outputs FW01/pri/act# show flash: filesys %Error show flash: (No such device) FW01/pri/act# show flash: all %Error show flash: (No such device) FW01/pri/act# show disk0: all %Error show disk0: (No such device) FW01/pri/act# show disk0: controller %Error show disk0: (No such device) So to me it looks like the whole ASA is running off RAM! Real bad! I could either risk loosing the config and rebooting the box or hoping it'll clear out the disk issue once it reboots and it comes back online working OK. I also couldnt upload a new .bin file to the disk0 of the device, seeing how the ASA itself couldn't even see it! Aftering attempting to run the checkdisk, it all showed failed. FW01/sec/act# fsck disk0: fsck of disk0: complete WARNING: Restoring security context mode failed. WARNING: Restoring cluster interface mode failed. Looked to me like rebooting this guy would cause an RMA call to TAC. And sure enough -- it did. Turns out we hit a bug CSCub40805 -- which in my case the fix WASNT to reboot the ASA since we lost connection to the box, but to simply RMA a new ASA since the flash/disk0 was basically shot. So whats the moral of the stor
