Where is the crashinfo file in the ASA filesystem?

Unanswered Question
Oct 30th, 2009

Hi all

Our Cisco 5550 rebooted today and we can see there is some crashinfo with the command:

show crashinfo

However, the text output is very long and I'd like to copy this file onto my PC rather than looking through the serial port session. I can't seem to see any actual file called crashinfo on the ASA filesystem. Can anyone tell me if this file exists and where it can be founf and its name?

Many thanks in advance




I have this problem too.

It's normally on disk0. You can type dir all-filesystems and it will show all your file systems.

Hope that helps.

Hi Colin

Thanks for the tip. Yes, that is where I thought the file would be but I cannot see it. I've used the ASDM file manager function to browse the drive and also the serial connection. I can see the various ASDM and software revisions, but that's all.

I guess by default this feature is diabled to save to the flash

You can try to use the commands below

config t

no crashinfo console disable

no crashinfo save disable

The command:

show crashinfo save


crashinfo save enable

Which as I understand it, should save it to a file, which is why I'm a little confused.

I agree it's confusing. If you check the link, it states To disable crash information from writing to Flash memory, use the crashinfo save command in global configuration mode. To allow the crash information to be written to Flash memory, and return to the default behavior, use the no form of this command.. Scroll up on the link above and you will see more info on configuring crashinfo.

Ah-hah. What a lovely bit of logic. Why use a single positive statement when a double-negative can do the same thing!

Thanks for your help, much appreciated. Now if it does crash again, things should be easier to sort out.
