After the node has successfully joined the cluster present all additional storage LUNS to the node. Please
refer to the Cluster Storage Guide located in the Cluster tab for additional information on adding and
configuring additional physical disk resources.

Geographically dispersed clusters

Cluster nodes can be geographically dispersed to provide an additional layer of fault tolerance.
Geographically dispersed clusters are also referred to as stretched clusters.
The following rules must be followed with geographically dispersed clusters:
• A VLAN connection with latency of 500 milliseconds or less ensures that cluster consistency can
be maintained. If the VLAN latency is over 500 milliseconds, the cluster consistency cannot
be easily maintained.
• All nodes must be on the same subnet.

HP ProLiant Storage Server software updates

After cluster installation has been completed, run the cluster update tool located in the Cluster Installation
Guide in the WebUI. The Cluster Installation Guide is located in the Cluster tab. This must be done after
the cluster installation is complete. It is necessary to run this tool on all cluster nodes.
