Cluster upgrades, backup and restore
Upgrading a cluster
Instructions for upgrading and downgrading clusters are contained in
Deployment
Guide.
Backing up a cluster
The
backup and restore
process can be used to save and restore cluster configuration information.
The backup process saves all configuration information for the cluster, regardless of the VCS used to make
the backup.
Restoring a cluster
You cannot restore data to a VCS that is a part of a cluster.
To restore previously backed up cluster configuration data you must follow this process:
1. Remove the VCS peer from the cluster so that it becomes a standalone VCS.
2. Restore the configuration data to the standalone VCS.
3. Build a new cluster using the VCS that now has the restored data.
4. Take each of the other peers out of their previous cluster and add them to the new cluster. See
cluster [p.162]
for more information about adding and removing cluster peers.
Clustering and Presence
Clustering supports the use of Presence.
All peers in the cluster must have identical SIP domain, Presence Server and Presence User Agent (PUA)
n
configuration.
If peers in the cluster have the PUA enabled, each peer publishes information about its own local
n
registrations. This information is routed to a Presence Server authoritative for the cluster's domain.
If peers have the Presence Server enabled, the Presence database is replicated across all peers in the
n
cluster.
When viewing presence status on a peer in a cluster:
Publishers shows all presentities across the cluster for whom presence information is being published.
n
Presentities shows any presentity for whom a subscription request has been received on the local VCS
n
only.
Subscribers shows each endpoint from which a subscription request has been received on the local VCS
n
only.
Clustering and Cisco TMS
Cisco TMS version 13.2 or later is mandatory if your cluster is configured to use FindMe or Device
Provisioning. From X8.1 onwards you must use Cisco TelePresence Management Suite Provisioning
Extension.
