Two IOS images in flash - how to boot from the other one?

Unanswered Question
Nov 8th, 2007

A contractor used a flash drive to copy a new IOS image into flash; however, I cannot get the second image to boot - a 'boot flash:[file]' command had no effect after reboot.

3560#sh flash

Directory of flash:/

2 drwx 192 Feb 28 1993 19:09:36 -05:00 c3560-ipservices-mz.122-23

406 -rwx 109 Feb 28 1993 19:09:36 -05:00 info

407 -rwx 616 Feb 28 1993 19:02:31 -05:00 vlan.dat

409 -rwx 79 Feb 28 1993 19:07:25 -05:00 private-config.text

410 -rwx 9031259 Nov 8 2007 12:30:34 -05:00 c3560-ipservices-mz.122-4n

411 -rwx 7382 Feb 28 1993 19:07:25 -05:00 config.text

Are there any commands to move images within flash directories, or how else can I direct the boot loader to the second image?

Thanks,

Marc

I have this problem too.

Hi Marc

Just to confirm have you tried the following command in config mode

boot system flash flash:"filename" ?

Thanks for the replies, guys;

The original image is: c3560-ipservices-mz.122-23

The new image is c3560-ipservices-mz.122-40

The output I showed depicts the 'sh boot' following my command 'boot system flash:c3560-ipservices-mz.122-40':

3560#sh boot

BOOT path-list: flash:c3560-ipservices-mz.122-40.SE.bin

It's as if the switch is booting the old image despite what the command says to do.

Since the new image was copied from a usb drive, might the location of the image in the flash directory play into whether it can be "seen" by the hardware?

Directory of flash:/

2 drwx 192 Feb 28 1993 19:09:36 -05:00 c3560-ipservices-mz.122-2

406 -rwx 109 Feb 28 1993 19:09:36 -05:00 info

407 -rwx 616 Feb 28 1993 19:02:24 -05:00 vlan.dat

409 -rwx 79 Feb 28 1993 19:07:25 -05:00 private-config.text

410 -rwx 9031259 Nov 8 2007 12:30:34 -05:00 c3560-ipservices-mz.122-4

What's the difference between "drwx" and "-rwx" ?

Marc

The difference is

drwx = this is a directory that contains files

-rwx = this is a file.

What you have is

2 drwx 192 Feb 28 1993 19:09:36 -05:00 c3560-ipservices-mz.122-2

This is a directory and contains not just the IOS but also html files etc. which allows you to configure the switch via a web interface

410 -rwx 9031259 Nov 8 2007 12:30:34 -05:00 c3560-ipservices-mz.122-4

This is just the IOS file itself - not the directory so you won't be able to configure it from the web interface. But it should have a .bin suffix. Your

boot system flash:c3560-ipservices-mz.122-40

should read

boot system flash:c3560-ipservices-mz.122-40.SE.bin

if that indeed is the IOS you are trying to load.

Jon

the =drwx signifies a directory, that is created when you use the archive /download-sw command using a zipped .tar IOS image package.

It has a lot of web page images and code. The actual bootable .bin image in that directory is down a sub-directory. Whenever you see a -drwx you can drill down it using the old dos style CD command, followed by the directory name.

I'm not sure if your screen outputs are complete, there's no -40.SE.bin in the output you are showing.

I believe 3560's, as well as other gear, boot the newest valid IOS image it comes across, so if there's a corrupt image or it can't find the image, it looks for another image.

I would recommend you recheck the filenames in flash:\. What you're showing is not complete. Either that or change the boot statement to include the actual file name of the image in flash:

Or, I would recommend deleting the 122-40-SE.bin file from flash and using the archive /download-sw /overwrite command with the .tar version of the image on a tftp server.

Yes, the output was incomplete:

I didn't make any other changes, but apparently a second reboot got the image to stick:
