We have a cluster of two CUCM 9.1 and have noticed that the service Cisco DRF Local on the subscriber fails by it self.
If we start the service manualy then we are able to backup the subscriber but some time after that the service would fail. When this happens our scheduled backup does not work. There is no problem with the backup of the Publisher.
Not sure if important but the cluster was upgraded from CUCM 7.1.5 using jump upgrade procedure.
Does anyone have an idea what could cause this or how to troubleshoot?
So if I regenerate IPSEC certificates will that affect other operations of the cluster like MGCP gatway or IP Phones?
From what I read here if there is a mismatch of serial numbers of ipsec.pem certificates I should download the cert from the affected Subscriber and upload it to the Publisher. Should I recreate the ipsec certificate on the publisher as well?

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
