Image deployment

I am trying to use ciscoworks (LMS2.5.1 running on windows 2003) to deploy software images. For now i am trying 3750 switches.

I am having problems with TFTP from the switch to the CiscoWorks server: when the switch is trying to backup its old image by putting it on the CW server, I get a permission denied error. After that, CW still erases the flash on the switch, but the job fails.

I tried the following scenarios manually between the switch and the TFTP server on the Ciscoworks box:

1. Get any file from the TFTP root directory: successful

2. Put a new file on the TFTP root dir: failed -- permission denied

3. Put a file that already exists on the TFTP root dir (overwrite it): Successful

I have two questions:

1. is there a setting I should be doing to the TFTP server to enable writing a new file in the root dir?

2. why is the CW server erasing the flash on the switch despite the job failure?

Thanks,

Nathalie~

Re: Image deployment

TFTP requires that the file exist on the server with write permissions before a transfer can begin. RME should handle creating this file provided it can write to NMSROOT\tftpboot and you are using our TFTP service.

I would have to see a swim_debug.log for this job with Software Management debugging enabled to know why it proceeds with the job after the image backup fails.

Re: Image deployment

As you said that this is a normal TFTP behavior, I looked into the debug file and the telnet file and here's more info:

The first step failed: copy flash to tftp. the debug file points to the telnet file for more info. I am including below parts of the debug and telnet files:

This is only the first step: backup of existing image. Despite the backup failure, the job continues, and the next step is erase the flash, which is the only part of the job that gets executed successfully. So, I do not understand why at the end the result is an empty flash, and the upgrade did not succeed. After this, I do not trust CiscoWorks to upgrade switches on the network.

Then while loading the new image to the flash, another error occurs. This is the output in the switch_telnet.log:

archive download-sw /overwrite tftp://CW_IP/rep_sw_8867589903959940153

Could not buffer tarfile...using multiple downloads

examining image...

%Error opening tftp://CW_IP/rep_sw_8867589903959940153 (Timed out)

%Error opening flash:update/info (No such file or directory)

ERROR: Image is not a valid IOS image archive.

Note that I used this same image to update the IOS of the switch manually, and it turned out to be a good image. The manual upgrade went smoothly with no problem.

I have checked that there is not firewall blocking traffic between the switch and the CW server. I don't have a clue of what is going on here. Any suggestion would be appreciated.

Thanks.

Re: Image deployment

I can't say what is going on here, but it appears network related. It looks like the TFTP transfer is starting, then just times out. When you did this manually, did you execute all the commands that RME executed exactly how they appear in the telnet log?
