DMM and DMPs 4400G problem

[Houssam Chahine]

Good day everyone,

I have a DMM running version 5.2.1 and DMPs 4400G running as well ver 5.2.1. Everything was running smoothly until couple of days ago, when out of sudden, the DMM starts seeing the DMPs as down. Physically the DMPs are running and are reachable. Furthermore you can browse the DMPs from the DMM itself even when stating them as down.

I tried to restart the DMM and the DMPs, and to restart the services. Once the DMM is up after reboot, it starts discovering the DMPs as up, and after like 1min it shows them as down therefore i can't publish any media content, though the DMPs are pingable and can be browsed.

Does anyone have any idea about this issue.

Thank you.

This sounds like the security certificate expired.  You can find out more in this notice: http://www.cisco.com/en/US/customer/ts/fn/636/fn63682.html

You'll probably need to upgrade the firmware on your DMPs.  If you don't have too many, you may not need to run the hotfix, otherwise, I'd recommend the hotfix to the DMM so you can use it to schedule the updates to the DMPs.

I tried to open the link, but the page displays "Forbidden link or application". Any alternative link?

Thank you in advance.

I found the solution for that on cisco website. I tried it and it worked perfectly. The solution is as per the below:

Communication can fail between Cisco Digital Media Manager (DMM) and its inventory of Cisco Digital Media Players (DMPs). However, applying the hotfix to your DMM server should prevent (or recover from) this failure in 10 minutes or less. In an affected deployment, error messages indicate that digital certificate expiration is the root cause.
 
NOTE:   Because the certificate expired, you can no longer use the “File Transfer to DMP” advanced task in DMM. Please use DMS-CD, instead. See CSCty23792 in Bug Toolkit on Cisco.com.

 
BEFORE YOU BEGIN! 
• If your DMM appliance is part of a high-availability cluster, STOP NOW. Open a case with Cisco TAC to have the hotfix installed for you. These instructions do not apply to you.

• Back up your DMM appliance.
