Dear Voipers,

We are upgrading our callmanager 3 nodes cluster from version to version
We have successfully upgraded the publisher and one of the subscribers.
The issue is when trying to upgrade the last subscriber using the OS Administration
interface>Software Upgrades>Install/Upgrade and after specifying the local source we
have an error message : An unknown error occured while accessing the upgrade file.
Please note the following :
- We are using the same DVD used to upgrade the first 2 nodes
- We have tried using Remote Location (SFTP) and we got the same error
- We have rebooted the server and tried again using DVD then SFTP but we got the same

Thanks in advance.

I had a similar problem a while ago and what I had to do was execute the upgrade from the command line.  It was the only way to get the upgrade to work.  I also so inconsistency on when I had to follow this method and when the GUI worked fine.  I tested this on multiple systems and multi-node clusters.  The issue wasn't common, but I hit it more than once.

I documented my procedure in the following URL.  Hopefully it helps you.
