How to: Load a compact flash via card reader


Good morning, CSC.

Is there a way to load a spare compact flash with a running-config, ASA IOS, & ASDM software via card reader? I need to load another flash card with all of the settings necessary for normal operation. This "spare" card will replace the flash that is currently in use. The reason for the replacement is capacity and because of changes made to the running-config. The "in-use" card is 256MB, the "spare" one is 512MB. Also, the new card will have a few changes made to the running-config, so it will, in essence, be a reload.

I have a card reader for the compact flash cards. If there is a way to load up this new card using the card reader, without monkeying with the firewall, I would prefer that. Like I said in the previous paragraph, this new flash card will replace the other one, once it's ready.

Hardware: ASA 5510

CF: 256MB (wanting to upgrade to the new 512MB card)

ASA IOS: 8.4

Thoughts, comments, and opinions welcome.

Thanks in advance!

Best regards,

Josh Dunbar

I've done it a bunch of times. Copy the files from your current flash to your PC with TFTP/FTP. Then place the 512 card in the ASA and format it. Put the 512 in the card reader and copy the files that you TFTP'd to your PC to the 512 card. Once complete put the 512 card in the ASA and make sure you can read it (dir /all). Note that the configuration file is not stored on the flash card. You can copy the config to it then copy it into running config, save it and then it is in NVRAM where it is stored.

Hope it helps.

I don't suppose there's a way that I can do this without interrupting the firewall? I want to leave the firewall up until I am ready to swap flash cards. I could just format the flash card with diskpart in Windows, instead of the ASA formatting it, right? If it's FAT, FAT32, or NTFS, I can.

And for clarification, the running-config isn't stored on the compact flash? Where is it stored? The NVRAM?

Thanks Collin.
