My ASA reloaded and now gets stuck at Loading Boot Loader... when booting. i tftp'd an image to the asa in rommon, but while its booting i see that it failed to mount disk0: (the flash). Once it is completely booted a dir disk0: show that disk0: has 0 bytes available 0 bytes total. any ideas?
I had a asa 5520 that had a corrupted flash. So I formated the flash, and reloaded. The device came up in Rommon. In rommon, I set the address, server, gateway, image and port. When I run tftpdnld, I can execute the image and escape out of rommon to the ciscoasa prompt, the pwd is blank, so now i am in ciscoasa# enable mode.
Like, you I see the mount errors and the disk space on my flash is 0 bytes.
At this time, I format the flash again. Now the flash looks good. Now, I need to prepare the device to connect to my tftpserver to download the image (asa and asdm) and perhaps a backup of the config to the device. Once that is done, now, I can re-download the image to flash and write mem without any issues.
I have seen this on 5510 and 5520. Where I have to format the flash that second time.
I have a question that goes along with this. My friend had a case where his flash did something similar. He did not reformat it, but was wondering if there is any way to recover the activation key, as he had not taken note of it before?
what activation key? the 3DES/AES key can be gotten at anytime, through the website all you need is a serial number. When this happened to me i just searched through old emails and found it, they should have sent him an email with the activation key in it...
thanks for your help. I ended up purchasing a flash card and replaced the one i was having problems with. I even put the card in a PCMCIA flash card reader formatted it and copied the image over from my laptop. this still resulted in the same problem.
