Hi, this evening i had this issue at my office publisher and subscriber went down, i still dont know exactly why
We are using call manager 4.0
When i step into the cpd publiser was off and subscriber was on, but i couldnt reach it by ping.
I think that they have rebooted due to a temperature issue, and critical file of subscriber have been corrupted in the process (i know that for sure)
I have a couple of questions about it
1. How do i reinstall de subscriber, i know the configuration, but i allways have done it in a lab enviroment, never on a "real" call manager and i cant get the proccess started, in the boot order is selected Cd as first option but allways boot from the corrupted installation
2. How can i found out what happened? im assuming that i lost all the iformation on subscriber, but im sure that it happened the same to the publisher, there is any kind of system logs in the call manager 4.0 or the windows server that can tell me what happened in order to avoid this kind of problems in the future?
Thanks for your help in advance, this is my first "serious problem" since im into voice ip and in this position so all help will be greatly apreciated
If it's a HP server... once you have the server back up, check in Start/Programs for any HP or Compaq folders - there used to be a utility called 'Embedded Management Log' that stored system hardware related events somewhere in the server (separate to the OS, so would survive a rebuild of the OS).

I am assuming that your Publisher is OK and that your Subscriber won't boot or you're getting some sort of critical error upon system startup...in other words, I'm skipping troubleshooting and going to the root of the question.
1) How do you rebuild the Subscriber? You need to rebuild the Sub from scratch using the CD or DVD for your version of CUCM. I suspect that you may be missing a boot sequence message that says something to the effect of "To boot from CD, press ...." and if you don't, the system will boot as it normally would. So, you need to rebuild the Subscriber to the exact OS patch level and CCM patch level as the Publisher. You should also re-use the hostname and IP settings or you will need to add a "new" Sub in CCM Administration on the Publisher before you add it to the cluster.
2) How do you find out what happened? Well, you have Windows OS logs that are of most value if you believe you had an environmental issue. However, these types of issues are sometimes difficult to run down. If you rebuild the Subscriber, the logs will get wiped out so you'll have to go by what you find on the Publisher. Dont forget to check the Dr. Watson logs as well.
