Adding a VCS to an existing cluster
Follow this process if you have an existing X8.5 cluster (of one or more peers) to which you want to add
another VCS peer. If you do not have an existing cluster, following the instructions in the section
another VCS peer. If you do not have an existing cluster, following the instructions in the section
.
This process will add an X8.5 VCS to the cluster and replicate the cluster master’s configuration onto that
VCS. Note that:
VCS. Note that:
n
You can have up to 6 VCSs, including the master VCS, in a cluster.
n
Only one VCS must be added to the cluster at a time.
Prerequisites
General prerequisites:
n
If Device Provisioning is enabled, or FindMe is managed by Cisco TMS the existing cluster of 1 or more
peers must already be running using Provisioning Extension mode.
peers must already be running using Provisioning Extension mode.
n
All VCSs to be included in the cluster must be running the same version (X8.5) of VCS software.
Add the new peer
On the master VCS:
Ensure that the master VCS does not list this new VCS peer in any of its neighbor zones or traversal zones
(
(
Configuration > Zones > Zones
).
Note: The Master VCS will be the source of the configuration for this new VCS peer and all other VCS peers
in the cluster. When a VCS is added to the cluster, its configuration will be deleted and replaced by that from
the Master.
in the cluster. When a VCS is added to the cluster, its configuration will be deleted and replaced by that from
the Master.
On the VCS to be added to the cluster:
1. Check that no other VCS (anywhere in the organization) has this VCS’s IP address in its clustering peers
list.
2. Backup the VCS (
Maintenance > Backup and restore
).
3. Using the web interface, review the configuration to ensure that the VCS has:
l
A valid Ethernet speed (
System > Network interfaces > Ethernet
).
l
Valid IP address and IP gateway (
System > Network interfaces > IP
).
l
The same set of option keys installed as those that will be installed on all other peers of the cluster
(
(
Maintenance > Option keys
).
Note that the number of call license keys may be different on different peers; all other license keys
must be identical on each peer.
must be identical on each peer.
l
At least one valid DNS server configured, and that if unqualified DNS names are used elsewhere (e.g.
for the NTP server), that the correct Domain name is also configured (Domain name is added as a
suffix to an unqualified DNS name to make it into an FQDN) (
for the NTP server), that the correct Domain name is also configured (Domain name is added as a
suffix to an unqualified DNS name to make it into an FQDN) (
System > DNS
).
l
A valid and working NTP server configured (
System > Time
; in the Status section, the State should
be “
Synchronized
”).
l
No peers configured (
System > Clustering
– all Peer x IP address fields on this page should be blank.
If not, delete any entries and click Save).
