Command to see Flash contents in old IOS version?

[GeneralDzur]

Updating the routers IOS image. It is currently using 12.1(3r)T2. I can't use the command "copy tftp: flash:" because the "flash" word isn't in the command syntax.

These are the available options:

917_gw_rtr#copy tftp: ?
ftp: Copy to ftp: file system
lex: Copy to lex: file system
null: Copy to null: file system
nvram: Copy to nvram: file system
pram: Copy to pram: file system
rcp: Copy to rcp: file system
running-config Update (merge with) current system configuration

startup-config Copy to startup configuration
system: Copy to system: file system
tftp: Copy to tftp: file system

I want to update the IOS - which option would I choose? thanks

Try not typing the :

Command as follows:

router#copy tftp flash

Hmmm..what platform of router is it?

I have 12.1-9a on a 2524 and it shows copy tftp: to flash:

Try downloading Router Software Loader from cisco's website and see if that helps.

 

[GeneralDzur]

JOAMON - trying it w/out the semicolons didn't work. It still doesn't recognize the word "flash".

ReadRight - I'm going to the cisco website now to download the Router Software Loader. Do you have to be a registered user?

[JOAMON]

Please post a show version and lets see were the router boots from.

 

[JOAMON]

Also....do you have the option to do a show flash? If so please post also.

Hello there, On 25xx platforms to be able to upgrade the IOS you must be in bootmode as you can not erase an image while the router is running that image. On this router platform the main IOS image is running from flash. Just change the configuration register to 0x2101 (or 0x2141 if you have any boot statements command in your existing config). Once in bootmode you will be able to use copy tftp flash. Cheers and good luck

 

[GeneralDzur]

Here is my show version. Tecnikall - it's not a 2500 series, it's a 26xx. I'm not sure if that matters. When i attempt to use the RSL (Router software loader) from Cisco, it says that it can't find my flash memory. ???

Hi Stephan, it looks like you don't have any internal flash. Maybe the router was loaded using a flash card with 12.0(7)T image on it and at a later stage the flash card was removed. Can you console into the unit and capture:
show file system
show flash
If no flash on next reload the router will not be able to load any valid images. One last thing just do a show run and see if you have any boot statements commands pointing to a tftp server where the router may load the image on reload. Cheers and good luck.

 

[ReadRight]

Strange. The image file says it's booting from flash, and I see your up time is only 15 hours so you've reloaded recently. I guess you can always open it up and have a look. Here's the board layout:

We reloaded the router recently because our satellite connection went down and we had to re-install a new satellite and Indoor Unit. I learned on-the-fly how to setup NAT, with my boss watching. very proud of myself. Anyway, back on subject. Here's my 'show file system'

Hi Stephan,

You don't have any flash hoding an image on it... It looks like someone used a Flash Card and after the router loaded the image the flash card was removed. If you reload this router it will end up in rommon mode. The solution will be to either add internal memory (sims) to the unit or use an external flash card. Cheers and good luck

 

[ReadRight]

And yet the router boots, and SH VER shows that it's booting from flash.

If you ever have a chance during downtime, plug a console cable into the router and watch the boot process through that...see if it complains about any errors as it boots.

I watched it boot during our last downtime (re-installation of internet satellite dish), and it didn't show any errors. Could it be that the flash is corrupted? Its confusing me, I'll admit.

I just got done upgrading the IOS, Flash, and Memory in 2 of our 2600(a 2620 and a 2621) routers. These don't have removeable flash card like the 3600 series so if it's not going to rommon, then there must be flash in it.
You should be able to do a DIR command at the enable prompt.

[b]router#dir [/b]
Directory of flash:/
    1  -rw-     9907088              <no date>  /c2600-is-mz.122-6.bin

16777216 bytes total (6870064 bytes free)

I also copy our running config there " just in case". See if you can do that....

FPCR001#copy run flash:
Destination filename [running-config]? 

Verifying checksum...  OK (0xF8CC)
4855 bytes copied in 1.304 secs (4855 bytes/sec)

There must be something wanky with your flash wafer. Try getting a new flash on ebay and try it out. Hopefully it's just the flash and not something on your motherboard.

Another thing you might try is set it up to boot from tftp then see if anything changes...if it does then it's just a corrupt IOS. Then once booted with a new IOS from tftp you can try re-initializing the flash. [COLOR=red yellow]DISCLAIMER!![/color] Be careful though, if anything goes wrong after re-initializing flash there may be no going back in a hurry. This is a production router, right?

That's really all I can think of. I haven't come across any known bug reports resembling this.

 

[ReadRight]

On second thought if it's a production router maybe you'd better just go with a new flash

That way at least you should have a fallback where you can just pop in your old flash and be back where you started from as a worst case.

 

[GeneralDzur]

Yeah, we're looking at purchasing a new flash off eBay.
