Re: Difficulty upgrading IOS on 3750 switch & switch stack - Page 2

ksuchewie · ‎04-28-2011

I have already opened a TAC case to try and resolve this problem, but TAC is really not being helpful in answering my questions or answering them timely. This has been a case for 2 weeks now.

I want to upgrade the IOS for my switch stack Current IOS on stack switches is 12.2(46)SE, which has known issues.

Stack setup:

1 - 3750-48PS - C3750-IPSERVICESK9-M

2 - 3750-48PS - C3750-IPSERVICESK9-M

3 - 3750-48PS - C3750-IPSERVICESK9-M

4 - 3750G-48PS - C3750-IPBASEK9-M

5 - 3750G-48TS - C3750-IPBASEK9-M

Coincidently on Monday (4/25) the flash on switch 1 in my stack went corrupt. The IOS on the replacement switch that arrived today to replace the faulty switch is 12.2(35)SE5, so if I just swap the switches right now there would be a version mismatch.

So my thought was to just upgrade the new switch first...ok:

How do I upgrade the image if there isn't enough space?

Isn't the /overwite command supposed to overwrite? Is the new image just too big for the flash?

When I have to upgrade the rest of the stack what would be the easiest way? I've seen notes about using the boot auto-copw-sw command, but how woudl that work with the 2 switches that are different? I've already downloaded the appropriate software for those 2 switches. When I mentioned the different models to cisco they made it sound as the different model switches had different coding within the ios image, even though after I've downloaded them they appear exactly the same in terms of file name & size;

3750-48PS - IPservices image: c3750-ipservicesk9-tar.122-55.SE1.tar = 15.3 MB

3750G-48PS - IP base image: c3750-ipbacsek9-tar.122-55.SE1.tar = 14.5MB

3750G-48TS - IP base image: c3750-ipbasek9-tar.122-55.SE1.tar = 14.5MB

I won't use the IP services image for my 3750G switches since they aren't licesned, but looking at the download files they appear the same as the 3750-48PS IP services image:

3750-48PS - IPservices image: c3750-ipservicesk9-tar.122-55.SE1.tar = 15.3 MB

3750G-48PS - IP services image: c3750-ipservicesk9-tar.122-55.SE1.tar = 15.3MB

3750G-48TS - IP services image: c3750-ipservicesk9-tar.122-55.SE1.tar = 15.3MB

Thank you for any help you can prove to get me up & running!

Hi,

Well, you can make it. Please show the output of the following command.

Switch#show boot

HTH,

Toshi

ksuchewie · ‎04-28-2011

I changed the boot command after it uploaded. I don't know if the "Premature end of tar file" is cause for concern?

Switch1#show boot

Is anyone else running ipservices 122-55-SE1 that can compare flash?

Hi,

Okay you alreay did what you should. Now you can do this for other switches in the stack. You may use "copy flash:NewIOS flash2:" and then "boot system switch 2 flash2:NewIOS".

Good Luck

Toshi

Antonio Knox · ‎04-28-2011

I follow what you're saying now. I was thinking in terms of a single switch. I'll have to think about that one a bit.

ksuchewie · ‎04-28-2011

In terms of my new replacement switch, you can still think of it as a single switch. I have not replaced them yet. If you really want I can delete the flash and copy over the tar file. I just don't think it will boot correctly afterwords without the tar extracted into flash ? I guess it depends if the switch reads the .tar file as a .tar file, or a directory?

ksuchewie · ‎04-28-2011

This does not look good....

Error loading "flash:/c3750-ipservicesk9-mz.122-55.SE1/c3750-ipservicesk9-mz.122-55.SE1.bin"

Interrupt within 5 seconds to abort boot process.

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

Thotsaphon Lueangwattanaphong · ‎04-28-2011

Hi

all right , its gonna be a long thread.

switch:dir flash:

go to the next step>

switch:dir flash:c3750-ipservicesk9-mz.122-55.SE1

then go to the next step>

switch:boot flash:c3750-ipservicesk9-mz.122-55.SE1/c3750-ipservicesk9-mz.122-55.SE1.bin

What's the result?

If you see no image there, its time for xmodem.

HTH,

Toshi

ksuchewie · ‎04-28-2011

Can't remember the result, but it fails. I'm already in xmodem, copying over just the .bin now. I'm familiar with the process, was hoping to avoid. It really stinks how slow the transfer is in xmodem. looks like it will take just around 4 hours to send over the image. (12 meg)

FYI, if you see "Premature end of tar file", and even though it appears everything is copied over, don't reboot your switch. delete your flash and try uploading again.

Thotsaphon Lueangwattanaphong · ‎04-28-2011

Hi,

Sorry guy. Don't give up. It's not that hard to upgrade the IOS.

Have you tried the following command to speed xmodem up?

 switch: set BAUD 115200
  

HTH,
Toshi

ksuchewie · ‎04-28-2011

Thank you. I totally forgot you could change the baud speed. Now it says it will transfer in 28 mins. Much better.

ksuchewie · ‎04-29-2011

I was able to get the switch upgraded an working this morning. Last night I started the XMODEM process and it copied over the .bin image. This morning I had it boot to that image. I deleted the flash again, and ran the command:

archive tar /xtract tftp://XXX.XX.X.XXX/c3750-ipservicesk9-tar.122-55.SE1.tar flash1:

It ran for awhile, it again said the "Premature end of tar file" error. At this point I thought there just wasn't enough flash memory to run the IP Services image w/ the web dev manager on a switch with only 16MB flash.

Thinking about the earlier comment to use, TFTPD32, I installed that on my pc and set it up to use that instead of Solarwinds. Just incase there were any other network issues, I closed out all software on my computer (outlook, cupc, etc.), and reran the command. (I did not delete flash) Then after awhile it said OK.

After setting boot path and reloading, I received this warning:

% There may not be enough space available to collect the complete crashinfo
% It would be advisable to have 282836 bytes free space on flash:crashinfo

I'm not worried about that warning since I have plenty of space on my 3750G switches (they have 32MB mem). Web dev is working as well. Now I can manually push the image down to 2 of switches in the stack, instead of manually updating. The other 2 (3750G), I will just have to break the stack and temporarily run them as standalone switches and manually update.

Leo Laohoo · ‎04-29-2011

This is a very common issue to the first generation of 3750. This is because this particular model only got a 16 mb flash capacity and the IOS you are loading is a FULL (tar file) and this >16mb. I have a number of 3750 in a stack and these models have 16mb flash. I only copied the .BIN file and it works.
