3750 IOS upgrade failure

[lcaruso]

Hi,

I'm trying to upgrade a 3750-24TS from c3750-ipservices-mz.122-25.SEE2 to a more recent image.

On the first pass, I got

Error: There is insufficient space in flash: to install the required
Error: image.  Clean up some old images, and try again.

So I used the delete /recursive flash:image-dir-name to clean out the old files, but I'm still getting the same message after doing this. What's the problem? Now I have a switch with no IOS and need to at least get something on there.

one last question...how do I reset the boot environment so it forgets about the last .tar based image and boots the .bin file w/o this error message?

Error loading "flash:c3750-ipservicesk9-mz.122-46.SE/c3750-ipservicesk9-mz.122-46.SE.bin"
Interrupt within 5 seconds to abort boot process.

If you only have one IOS then there's no need to set the boot variable.  Remove it using the command "no boot system switch all" (don't have a heart attack if the switch "pauses" for about 2 seconds).

Try this command: using tftp server tool and copy the new ,bin file in the directory where tftp server tool is installed.

Switch#copy tftp: flash:
Address or name of remote host []? "Your PC or tftp IP"
Source filename []? "New IOS .bin File_which you want to flash"
Destination filename [c3750-ipbasek9-mz.122-55.SE12.bin]? "Your currently installed or loaded(OLD) IOS name"
%Warning:There is a file already existing with this name
Do you want to over write? [confirm]

"After this this message will show"......
Accessing tftp://10.88.53.254/c3750-ipbasek9-mz.122-55.SE12.bin...
Loading c3750-ipbasek9-mz.122-55.SE12.bin from 10.88.53.254 (via Vlan1): !!!!!!!!!!!!!OOOO!!!!!!!!!!!!!O!!!!

After that reload or restart the switch then check the flash by typing command: show flash or flash:

if the flash is upgraded the save the configuration: wr mem

For the Catalyst 3750 (& 3560) switches with only 16MB FLASH there was a 'LM' release (Express Setup Files only) of the 12.2(55)SEx versions for the IP Services image that was smaller and would fit in 16MB FLASH.  It was the full IP Services image, however it had reduced management HTML files.  Since these switches are EoL the images have been removed from CCO, however the details are in the release notes:

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750/software/release/12-2_55_se/release/notes/OL23054.html

With the LM image you could perform the normal 'archive download-sw' command to upgrade the switch and it would set all the environment variables correctly so you don't get errors on booting.  I am guessing if you raise a TAC case you could get hold of the file, however I suspect a search online may help also.
