Switch 3750E IOS upgrade failure

[ethanenning]

Hi all,

I have a brand new switch 3750E (Model number : WS-C3750E-48TD-S), which would be upgraded to latest IOS.

I issue the following command to upgrade IOS:

switch#archive download-sw /overwrite tftp://1.1.1.2/c3750e-universal-tar.122-46.SE.tar

The output is below:

---------------------------------------------

extracting c3750e-universal-mz.122-46.SE/info (382 bytes)

Old image for switch 1: flash:c3750e-universal-mz.122-35.SE5

Old image will be deleted after download.

------------------------------------------------------

The switch got frozen, and I have to power cycle it. Then the switch boots up with old IOS.

It seems new IOS image file didn't overwrite the old one. I tried 3 times, the result. Any suggestion? Should I just delete the old one and archive new one?

Your help is appreciated.

Normaly you should get an error mesasge when there is not enough space. I would not delete the old one bevore.

Try firt this with the reload

archive download-sw /overwrite /reload

tftp:[[//location]/directory]/image-name.tar

try next to leave the old one. maybe it will work..

archive download-sw /leave-old-sw /reload

tftp:[[//location]/directory]/image-name.tar

look if there is not enough space...

hope this helps...

otherwise mabye a hardware error would i say

Hi Ethan, when the archive download is completed or successful the boot variable will automatically be updated with the new IOS image.

The overwrite keyword deletes the existing or current image in order to make room for the new one. If you use either /leave-old-sw, or /safe then this could cause problems if there is insufficent flash.

In both cases the old software is not deteled, with /safe it will delete the old image once the new one has been downloaded sucessfully.

If the overwrite does not appear to be successful, then I would recommend deleting the current image first before downloading the new archive without the need to overwrite:-

delete /force /recursive flash:/file-url

Hope this helps

Allan.

Pls rate helpful posts.

thanks everyone.

The switch has enough flash memory. Actually the new image file is already uploaded to flash, it just wasn't being extracted.

I tried switch#arechive /download ......

all commands doesn't work.

What i did is to copy tar file to flash mem, and from the flash mem, i extracted the file. And it is successful.

archive tar /xtract [tar file] flash:
