ASA 5520's unable to boot from disk1:

Unanswered Question

We recently purchased two Cisco compatible 512 MB flash drives for our ASA. The drives work fine when first inserted into the ASA. We are able to load boot images, ASDM, CSD on the flash cards. However, when we change to boot statement to boot off of the image on disk1:, after a reboot the ASA can't see disk1: until it is removed and reinserted. Here's an output of the boot load:

Cisco Adaptive Security Appliance Software Version 7.2(3)

.WARNING: BOOT variable added, but unable to find disk1:/asa803-k8.bin

*** Output from config line 93, "boot system disk1:/asa80..."

.............................................WARNING: interface inside security level is 80.

*** Output from config line 1335, "logging host inside 172...."

.Device Manager image set, but unable to find disk1:/asdm-603.bin

*** Output from config line 1361, "asdm image disk1:/asdm-6..."

You see that the ASA complains that it cannot find disk1:. Once the ASA boots, the CF card in slot1 cannot be seen until it is removed and reinserted. We tried this with two different CF cards (from the same Cisco compatible manufacturer) and two different ASA's, with the same results.

Anyone have experience with this?

Thanks,

Jon

I have this problem too.

Try this command "show run | inc boot" and the output should be as follows:

ciscoasa(config)# show run | inc boot

boot system disk0:/asa706-k8.bin

boot system disk0:/asa802-k8.bin

If there is no boot system command, the output should be null, so you need

to add the boot system command as follows:

ciscoasa(config)# boot system flash:/asa802-k8.bin

INFO: Converting flash:/asa802-k8.bin to disk0:/asa802-k8.bin

Now if you issue the command "show run | inc boot" the outpurt will be as shown below:

ciscoasa(config)# show run | inc boot

boot system disk0:/asa802-k8.bin

Use the following commands to save the config and then to reload.

ciscoasa(config)# write mem

ciscoasa(config)# reload

Performing the above mentioned steps might resolve the issue.also try removing the bootimages and add them back after a reboot.

Hi Jon,

If disk0 does not have a valid image, the boot loader will not look for an image in disk1 - since the presence of disk1 is not mandatory

This behavior is by design. This is the reason you get the error message "Cannot find disk1:/asa803-k8.bin".

Hope that helps.

Regards,

Vibhor.
