4503 IOS update failed...

[bmarmont_2]

I tried to update the IOS on our backbone switch going via the instructions attached. This failed and the switch continuously rebooted saying it could not load the .bin in rommon# mode.

I think I found the problem in the path being incorrect

nzaklnet1(config)#boot system ?

WORD TFTP filename or URL

flash Boot from flash memory

ftp Boot from a server via ftp

mop Boot from a Decnet MOP server

rcp Boot from a server via rcp

tftp Boot from a tftp server

nzaklnet1(config)#boot system flash ?

WORD System image filename

<cr>

nzaklnet1(config)#boot system flash NEWIMAGE NAME

boot-start-marker

boot system flash bootflash:cat4000-i9s-mz.122-25.ewa10.bin - should be?? boot system flash:cat4000-i9s-mz.122-25.ewa10.bin'?

boot system bootflash:cat4000-i9s-mz.122-25.EWA4

boot system bootflash:cat4000-i9s-mz.122-25.EWA4.bin

boot-end-marker

It would be displayed next to the filename, which it doesn't at the moment.

The problem you had was due to case sensitive differences between the string and the actual filename.

You can also verify the integrity of the file with the "verify bootflash: command and this checks the file . There is usually is a check at the end of the file download so it should show even at that point if there is a problem . In all my years I'm not sure I have ever run into a corrupted image that was downloaded so its a pretty rare event. If there is a problem it is usuauly syntax problems with the boot statements etc... Also as a check on your boot statements first doa a "dir bootflash: , then copy and then paste that image into your boot statement and this will eliminate the imagename that is not typed correctly.

Edison,

Are you sure you require boot system flash bootflash: ?

I checked by upgrading an IOS of a switch and setting the bootpath as

boot system bootflash:cat4000-i5k91s-mz.122-25.EWA9.bin which worked absolutely fine

Narayan,

I don't have the equipment at the moment to verify the syntax.

I'm going by the original post 'online help'.

If you notice, when the OP did

boot system ?

The correct option was flash

when he did boot system flash ?

It presented the image file name as the option. For completeness, one should include the word bootflash since that's where the image is actually stored.

Edison, i checked it and it works and hence wanted to know whether it is really required. It may be available from a particular code; i am using 12.225 EWA9

Basically iam presented with both flash and file name as options and hence i think its working

MS_BGM_L3_SW1(config)#boot system ?

WORD TFTP filename or URL

flash Boot from flash memory

ftp Boot from a server via ftp

mop Boot from a Decnet MOP server

rcp Boot from a server via rcp

tftp Boot from a tftp server

MS_BGM_L3_SW1(config)#boot system ?

WORD TFTP filename or URL

flash Boot from flash memory

ftp Boot from a server via ftp

mop Boot from a Decnet MOP server

rcp Boot from a server via rcp

tftp Boot from a tftp server

MS_BGM_L3_SW1(config)#boot system

Since you have the equipment available, what happens if you enter boot system flash bootflash:image-name.bin ?

Does it work as not using the flash option ?

I rarely use this command as I usually only have one image in flash

[royalblues]

will check it out, production hours just started and i dont want to experiment now :-)
