WISM Upgrade Failure

Unanswered Question

We have tried to upgrade two Wism from version 5.1.151.0. to 5.2.178.0.

At the first Controller the FTP transfer of the new SW was successful, but at the

second Controller the FTP transfer didn't start.

Following error message appears: “At least one AP is upgrading image, download cannot start”

However no AP is associated or is trying to download a image at this controller.

I have also tried to restrict APs for associating to the controller with “Authorize APs against AAA” - no effect.

A reboot of the controller is also not possible. - same error message.

Any feedback is welcome.

I have this problem too.

Try to shut the gig ethernet port on the chassis that goes to that wlc module. Use the service port to do the upgrade and see if that works for you.

May I clarify something? You said that you get this error message even if there are NO AP's associated to this WiSM, do you confirm?

Error still continues even if this WiSM is reloaded?

From show ap summary, there is no AP detected. as follows:

(wc-sg-sin-002) >show ap summary

Number of APs.................................... 0

Hi Edmond,

Can you do "sh sysinfo" on your WiSM and post the output please?

We have tried to shutdown the GigabitEthernet ports on the Chassis which is the Port-Channel to the Controller.

But if I start the FTP transfer for the upgrade over the Service Port , the same error message appears and the

download didn't start.

I *think* (emphasis on the word "think") the problem is your Bootloader Version (3.2.202.0).

Can you try upgrading the bootloader version in the following sequence:

4.1.171.0 ER

4.2.61.0 ER

4.2.112.0 ER

and finally the version where you are running your current firmware.

By the way, ER stands for Emergency Release. It's actually a "patch".

Note: The final "true" bootstrap version is 4.2.112.0 ER. Which means if you upgraded the bootstrap to 5.X, when you do a "sh sysinfo", the bootstrap will always report as 4.2.112.0.

How you were able to upgrade your firmware to version 5.X with a 3.X bootstrap is strange.
