[3750x] Switch failed to start on the new image

[Loic Zambon]

Good morning,

I updated the firmware of my switches 3750 x (19 switches in 8 stack group) with the new version. But 2 switches of a stack of 3 cannot take the last version. They are the same model, I don't understand why they cannot boot on the new image.

New version : 15.0(2)SE7

Old version : 12.2(58)SE2

Switches informations

Of the 17 Switches that works

WS-C3750X-24       15.0(2)SE7            C3750E-UNIVERSALK9-M

Model revision number                     : A0
Motherboard revision number          : A0
Model number                                  : WS-C3750X-24T-S

Of the 2Switches that not works

WS-C3750X-24       12.2(58)SE2           C3750E-UNIVERSALK9-M

Model revision number                     : A0
Motherboard revision number          : C0
Model number                                  : WS-C3750X-24T-S

This is the only different I found between the 2 switches with all other switches,

Image loading

In 1st step he load the image but he cannot boot and at the end he load the old image and boot on it.

The switch that has the last version can not see the 2 others stacks. At the moment the only solution that I found it's the downgrade of the switch with version 15.

A lot of people run into problems like this because during the so-called "IOS upgrade" they used the very old, old method of only COPYING the IOS BIN file and the main cause of the issue is the BIN file they copied into the appliance(s) are corrupt.  The output to the boot-up process confirms the IOS is corrupt.  

I would recommend to use the TAR file and upgrade the IOS of the stack using the tried-and-tested command of "archive download-sw /destination 1 /destination 2 tftp://<TFTP IP address>/filename.tar".  The command switch "/destination 1" and "/destination 2" means the IOS will be loaded into switch stack members 1 and 2.  If you have more than two (or more) switch stack members then you add "/destination N" where N are the switch stack members.

[Loic Zambon]

I used  the .bin only to have an exemple. At the first update I used this command (I used this command for all my stacks) :

archive download-sw tftp://AddressIP/c3750e-universalk9-mz.150-2.SE7.bin

In the stack only the 3rd take the update the 1st and 2nd not. I tried with this command :

archive tar /x tftp://AddressIP/c3750e-universalk9-tar.150-2.SE7.tar flash1:
archive tar /x tftp://AddressIP/c3750e-universalk9-tar.150-2.SE7.tar flash2:
conf t
boot system switch all flash:/c3750e-universalk9-mz.150-2.SE7/c3750e-universalk9-mz.150-2.SE7.bin

But they will not boot on the image.

In the stack only the 3rd take the update the 1st and 2nd not.

And what error message was presented?  Was it because there was no more available flash memory space?

[Loic Zambon]

I do not remember the error message (I'm not on site at the moment). But there was available flash memory space, I have the same result with the /overwrite parameter. He try to load the image v15 and he try again

Ok, I don't know about the others but that error message is key to your issue.  

Let us know if you have or remember what the error message is because there are heaps of possibilities why your appliance won't boot the right IOS.

The system is unable to boot automatically.  The BOOT
environment variable needs to be set to a bootable
image

I was able to install the image 15.0 (1) SE3. Hoping that the bootloader is updated I tried to put the 15.0 (2) SE7 again. it does not work.

Loic, 

You mentioned earlier that when you tried to upgrade the IOS there was an error message.  I want to know what this error message is.

[Loic Zambon]

The system is unable to boot automatically.  The BOOT
environment variable needs to be set to a bootable
image

It's just this. All other 3750X (with the same model) considers that this image are bootable, but not the switch with the C0 revision.

[Leo Laohoo]

Ok, post the output to the command "sh bootvar".

[Loic Zambon]

"sh bootvar" isn't available on 3750x. I have the "sh boot" command. When I'm on place I take the result of the command.

[Loic Zambon]

[Leo Laohoo]

Nope.  No idea.  Your issue has got me "stumped".  

[Loic Zambon]

No problem. With older v15 image all works.

Thank you for your time

Hi,

I'm trying to upgrade a 3750-X that I have here and run into a similar issue.

The switch refuses to boot either 15.0.2-SE7(MD) (c3750e-universalk9-mz.150-2.SE7.bin) or 15.2.3E(ED) (c3750e-universalk9-mz.152-3.E.bin)

When I try to load them, the output shows:

Loading "flash:/c3750e-universalk9-mz.150-2.SE7.bin"...@@@@@@@@@@@@@@@@@@@ [a total of 4989 x @ here] @@@@@@@@@@@@@@@@@@

or

Loading "flash:/c3750e-universalk9-mz.152-3.E.bin"...@@@@@@@@@@@@@@@@@@@ [a total of 6445 x @ here] @@@@@@@@@@@@@@@@@@

and then the @@@ stop appearing and the switch just hangs indefinitely.

The old image on the switch is 15.0(1)SE2, which boots fine.

This is a 3750-X from 2013, and sh ver also lists Motherboard revision number : C0
