Ios upgrade Failed

[jeftavaneijk]

I have upgraded my cisco 4500 with a new ios. I have set "boot system bootflash:cat4000-i9s-mz.122-20.EWA.bin" in my config.

Still the switch is booting with the old ios.

I have search on the intenet on sometimes i see "boot system FLASH bootflash:cat4000-i9s-mz.122-20.EWA.bin"

Is there a difference between?

Also i have a other 4500 upgraded with a supervisor II module with no problems.

It's "boot system flash bootflash:".

Where:

"boot" is the action.

"System" is what you want to boot.

"flash" is where you want it to run.

"bootflash:" is the device/directory your image resides

" is the IOS name & version you want to load.

I have uploaded the new IOS in the normal way. In my config there is:

boot system flash bootflash:cat4000-i9s-mz.122-20.EWA.bin

Still it's booting with the old ios.

When i do a sh ver i see

System image file is "bootflash:"

When i do a dir i see

1 -rwx 10249580 Feb 1 2005 04:52:47 +00:00 cat4000-i9s-mz.122-18.EW.bin

2 -rwx 12468232 Jan 26 2005 04:13:29 +00:00 cat4000-i9s-mz.122-20.EWA.bin

Sh bootvar show the following:

BOOT variable = bootflash:cat4000-i9s-mz.122-20.EWA.bin,1

What is going wrong?

Delete the old files and reboot.

I am running into the same issue. Were you able to fix it? I know that I can delete the old file...but I want to minimize the risk as I am configuring this remotely etc.

Can you please let me know if you were able to get around this.

Set the BOOT parameters so that the switch boots up with the downloaded image when reloaded:

For Example:

switch: set BOOT flash:.bin

(substitute the image name above for the IOS name you loaded to flash)

Note: BOOT must be in capital letters.

the switch must boot automatically.

(b) switch: unset MANUAL_BOOT

Go to the enable mode and run the show boot command to verify the BOOT parameters
