Peers share their bandwidth usage information with all other peers in the cluster, so when one peer is
n
consuming part or all of the bandwidth available within or from a particular subzone, or on a particular pipe,
this bandwidth will not be available for other peers.
For general information on how the VCS manages bandwidth, see the
Cluster upgrades and downgrades
The clustering feature was introduced to the VCS in software release X3.0.
Upgrading from versions prior to X3.0
If you are upgrading from VCS software versions prior to X3.0 and want to implement clustering, you must:
1. Remove any existing Alternate configuration.
2. Upgrade all VCSs to be added to the cluster to the latest VCS software version.
3. Follow the steps outlined in
Downgrading
See the
Upgrade procedure
Cluster backup and restore
The
backup and restore
process can be used to save and restore cluster configuration information.
Backing up a cluster
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 a 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
for more information about adding and removing cluster peers.
Clustering and FindMe
Clustering supports the use of FindMe. The configuration options available to the VCS administrator depend
upon whether or not the VCS is using the
information.
