Sep 10, 2014 | Bugs, Real World, Security, Self Improvement | 0 comments cisco asa format flash Ran into a strange issue today with a pair of Cisco ASA 5525x series routers. The FW are configured in a
%error Opening Disk0:/ (too Many Open Files)
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 https://quickview.cloudapps.cisco.com/quickview/bug/CSCub40805 while the other ASA constantly 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 http://www.nycnetworkers.com/self-improvement/cisco-asa-error-opening-disk0-many-open-files/ a datacenter with NO ONE around! Trying 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
