Suppose we have a Call Manager Cluster with one Pub + 2 Sub, how do we make sure they are in a cluster?
How do we check this in case of Windows based call manager and appliance based call manager?
On windows you could check the dblhelper, on linux it's very easy as you CANNOT install a SUB if you do not configure it before in CUCM admin. So linux just look at CCMadmin
if this helps, please rate
Thanks.. it has been very helpful.
In case the Subscriber in the Appliance based CUCM cluster goes out of sync or crashes out of cluster (hardware/software crash), will this reflect saying the subscriber is NOT a part of the cluster?
No, if it goes out of sync, it's because it's in a cluster. Standalone servers cannot be out of sync as they do not get info from any other server.
If it crashes just follow the document on replacing a server in a cluster.
Will there be any displayed on the ccmadmin page if the subscriber goes out of sync? Is this error shown pn Pub or on Sub?
no, use utils dbreplication commands to check status
Usage info available in OS guide for CUCM, all in CCO
Thanks a lot for all the info, its been very helpful!
