ls
there should be a file ‘clustermaster’ plus one directory for each Cisco VCS in the cluster, labeled
1, 2, …, 6
1, 2, …, 6
3. Type:
ls 1
ls 2
ls 3 etc
the directories 1, 2, 3 etc should have a file “alternatesconfiguration.xml”. If any is missing, it
needs to be manually copied.

Note: Directory 1 relates to the configuration of the Cisco VCS listed in the Cisco VCS Clustering tab
as Peer 1 IP address, directory 2 relates to the configuration of the Cisco VCS listed in the Cisco
VCS Clustering tab as Peer 2 IP address etc.

4. Log in as root to the IP address of the Peer X IP address that is missing the
“alternatesconfiguration.xml” file.
5. Scp the file /tmp/x5/peerconfiguration/X/alternatesconfiguration.xml to
root@<IP of dest VCS>/tmp/x5/peerconfiguration/X
where X is the directory ID missing the file.
where X is the directory ID missing the file.
a. The relevant username and password of the receiving Cisco VCS will have to be entered to
allow it to accept the file.
For example, if the Cisco VCS at 192.168.1.101 has directory 3 missing the
alternatesconfiguration.xml file, and Peer 3 IP address is 192.168.1.103 then log in to
192.168.1.103 as root and type:
alternatesconfiguration.xml file, and Peer 3 IP address is 192.168.1.103 then log in to
192.168.1.103 as root and type:
scp /tmp/x5/peerconfiguration/3/alternatesconfiguration.xml
root@<192.168.1.101>/tmp/x5/peerconfiguration/3
root@<192.168.1.101>/tmp/x5/peerconfiguration/3

On that non-master Cisco VCS:
Log in as admin on an SSH or other CLI interface. At the command prompt type:
xcommand ForceConfigUpdate
This will delete the non-master Cisco VCS configuration and then force it to update its configuration
from the master Cisco VCS.

Warning: Never issue these commands on the Master Cisco VCS, otherwise all Cisco VCS
configuration for the cluster will be lost.
