[cisco-voip] CUCM 12.5 issue with restore

[Wes Sisk (wsisk)]

Andy, sounds like a good start:
https://community.cisco.com/t5/ip-telephony-and-phones/disaster-recovery-problem/td-p/2767755

I see 2 other situations that might be relevant:
1. All the same .cop files not installed
2. Attempting to restore a backup of a different version

Wes,
I select Restore Wizard then select the backup device
click next
The Ccx then spins the hour glass for 5 mins then says
“Restore request timing out. Either master agent is down or Sftp server is inaccessible or too slow to respond”

It’s the same location all the other UC apps backup to. Could it be that there are too many files in the directory?
Even though they would have different names etc?

It seems to do a couple of hundred new sessions for some reason looking at the backup server syslog.
It’s keeping 14 versions of cucm cluster backups is that too many, although I’ve not seen anything to say so.

I’m going to change the file path tomorrow and see what happens with that.

What is the exact error? What do DRS logs show?

I see one report that after re-install dbreplication is not established leading to "Unable to send network request to master agent. This may be due to Master or Local Agent being down”

Resolved by resetting dbrepliaction for all nodes.

Thanks,
Wes

So I thought that if a CUCM could backup to and sftp server without issue, that it would be able to restore.
But that turns out to be wrong.

The cluster can backup to sftp without issue, but when I try to restore said backup, the restore seems to make a large amount of ssh connections and times out saying the DRS maybe down of the sftp server is tacking too long to respond.

this is the sftp server syslog output.
