The SAN connection tool must be completed and all the necessary software components
for connecting to the desired storage must be installed before the configuration of cluster
services.
It is required that at least one LUN has been presented for the configuration of the Quorum
disk. This LUN must be created from shared storage and must be at least 50 MB. (500 MB
is recommended). Additional LUNS may also be presented for use as shared disk
resources.
Cluster configurations should be deployed with dual data paths for high availability. Dual
data paths from each node enable a path failure to occur that does not force the failover of
the node. Clusters can be configured with single path, but if a failure in the path does
occur, all of the node resources will be failed to the non-affected node.
Caution: The version of Storage Manager (Quota Management software located under the
Shares tab) that comes installed on the server is not supported in a cluster. It must be
uninstalled prior to creating the cluster.The uninstall tool is located in the Cluster Installation
Guide under the Cluster tab in the WebUI. See Figure 117.
