Cause
With firmware 8.21 and higher, a "

code:

chkdsk

" function is automatically executed at system initialization in order to perform a DOS file system corruption check, with repairs as possible. This function will occasionally find something that needs to be corrected.

Solution

code:

...could not be repaired...

") is seen, then the repair routine could not fix all issues on this pass. If this occurs no more than a few times consecutively and is followed by the "

code:

...was repaired...

" messaging, then follow the "

code:

...was repaired...

" instructions below. Otherwise, if the condition persists in a reset loop then please contact the GTAC for assistance.

If the second set of messaging ("

code:

...was repaired...

") is seen, then the user should check that the configuration as displayed in the output of a '

code:

show support

' or '

code:

show config

' matches to the backup configuration file taken as of the last known config change. Apply any necessary corrections, but no action is warranted beyond that.
