I'm installing a new subsciber on a existing cucm cluster. I have added the new subsciber (system->server and then IP address og new sub) in the publisher administration webpage.
The new sub is being installed on a different subnet then the pub. There isn't a firewall between the new sub and pub. Less then 20 msek delay and 100 mbit between servers.
In the installation process I enable the DNS client and enters IP addresses of the DNS servers. I checked with the nslookup command and all servers can be resolved, hostname to IP.. But I get a DNS error?
Second issue - When the database is being installed there is no activity on the diskdrives and after 50 min. I get a "critical error" and the installation process stops. I tried this twice..
I had to reboot the existing cucm servers to update their rhost file.
But using the CLI command "utils firewall list" I can see that no "accept rules" has been added to accept packets from the new sub. Can this be the problem why the database installation fails?
