points the possible solutions. Prerequisites Requirements There are no specific requirements for this document. Components Used The information in this document is based on these software and hardware versions: Cisco ASA 5500 series with software version 8.0 and later The information in this document was created from the devices in 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. Conventions Refer to Cisco Technical Tips Conventions for more information on document conventions. Background Information Cisco ASA maintains its filesystem in an internal flash memory and stores all the files in flash memory. This is a memory card inserted into a slot in the ASA. The capacity of this depends on the ASA hardware model. Refer to the Technical Specifications section in Table 8 of Cisco ASA Data Sheet for more information. This memory is referred to as flash or disk0. When additional flash memory is needed, you could use an external flash card. Except for the ASA 5505 model

%error Opening Disk0:/.private/startup-config (no Such File Or Directory)
comments Ran into a strange issue today with a pair of Cisco ASA 5525x series routers. cscub40805 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 error opening disk0 / (too many open files) the ASAs in the pair didn't even let me get to the disk0 via #dr 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 http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/113266-asa-flash-error-ts.html 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 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) http://www.nycnetworkers.com/self-improvement/cisco-asa-error-opening-disk0-many-open-files/ 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 story? I'm NYer, and NYers are skeptical….sometimes. I didnt fully trust when the bug ID said "reboot and its fixed". I made sure to do a FULL backup of the #sh run using the #more system:running-config command and of course perform this during the proper maintenance window. Its times like these maintenance is where people loose their jobs. A upgrade or ma
