This is due to a manufacturing testing and this behavior is filed in Cisco bug ID CSCtf63643 ( registered customers only). There are certain instances where these recovery files can be seen on the flash of a freshly ordered Cisco ASA appliances. Note: The FSCK utility runs automatically at startup, so you can see these recovery files even if you did not manually enter the fsck command. In general, these files do not contain any vital data and can be safely deleted with the delete command. If you can view a number of these recovery files on the flash, these may result because of an automated testing process where the ASA might be power cycled too often. In case of any filesystem corruption issues, the fsck utility generates recovery files namely fsck00?.rec. Initializing disk0: cache, please wait.Done. A successful fsck operation results in this output: CiscoASA# fsck flash:Ĭhecking the boot sector and partition table. The fsck utility repairs a corrupt filesystem. You can execute the fsck utility with the fsck flash: command. It fixes the problem within the filesystem and save that as a recovery file. This utility usually runs automatically at the start-up of the device and verifies for any anomalies within the filesystem in case of any abnormal events. The term fsck is an acronym for filesystem check. When there are issues with the access of the flash filesystem, you can complete these steps that explain troubleshooting procedures. Mitigate Cisco ASA Flash Corruption Issues Show disk1-Displays the contents of the external flash memory. Show disk0-Displays the contents of the internal flash memory. Show flash:-Displays the contents of the internal flash memory. Note: The default current directory is flash:/. The contents of this filesystem can be verified with any of these commands:ĭir-Displays the contents of the current directory. If the flash filesystem is properly accessed by the device and works properly, the device indicates this with a Solid Green on the Flash LED on the front panel of the device. This flash card is also used to save the configuration files and referred to as disk1. Except for the ASA 5505 model, all other ASA models in 5500 series have an external compact flash card slot on the rear end of the device, which can be accessed by the user easily without the need to open the device. When additional flash memory is needed, you could use an external flash card. This memory is referred to as flash or disk0. Refer to the Technical Specifications section in Table 8 of Cisco ASA Data Sheet for more information. The capacity of this depends on the ASA hardware model. This is a memory card inserted into a slot in the ASA. Background InformationĬisco ASA maintains its filesystem in an internal flash memory and stores all the files in flash memory. Refer to Cisco Technical Tips Conventions for more information on document conventions. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. The information in this document is based on these software and hardware versions:Ĭisco ASA 5500 series with software version 8.0 and later There are no specific requirements for this document. This document describes different possible errors that occur because of the Cisco ASA flash corruption and also points the possible solutions.
