Configuring the Hard Drives on the Shared Storage System(s)
This section provides information for configuring the hard drives on the shared storage systems. The shared storage system hard drives must
be configured before use. The following sections provide information on these configurations.
Configuring and Managing LUNs
Configuring and managing LUNs is accomplished using the Navisphere Manager utility. Before using Navisphere Manager, ensure that the
Navisphere Agent service is started on your cluster nodes.
In some cases, the LUNs may have been bound when the system was shipped. It is still important, however, to install the management
software and to verify that the desired LUN configuration exists.
You can manage your LUNs remotely using Navisphere Manager. A minimum of one LUN (RAID drive) is required for an active/passive
configuration; at least two drives are required for an active/active configuration.
Dell recommends creating at least one LUN or virtual disk for each application. If multiple NTFS partitions are created on a single LUN or
virtual disk, these partitions will not be able to fail over individually from node-to-node.
Using the Windows Dynamic Disks and Volumes
The Windows operating system does not support dynamic disks (upgraded disks) or volumes as shared cluster storage. If the shared cluster
storage is configured as a dynamic disk, the Cluster Configuration wizard is not able to discover the disks, preventing the cluster and network
clients from accessing the disks.
Configuring the RAID Level for the Shared Storage Subsystem
The hard drives in your shared storage subsystem must be configured into LUNs or virtual disks using Navisphere Manager. All LUNs or virtual
disks, especially if they are used for the quorum resource, should be bound and incorporate the appropriate RAID level to ensure high
availability.
See " Installing the Quorum Resource " for more information on the quorum resource.
NOTE: Dell recommends that you use a RAID level other than RAID 0 (which is commonly called striping). RAID 0 configurations
provide very high performance, but do not provide the level of redundancy required for the quorum resource. See the documentation for
your storage system for more information about setting up RAID levels for the system.
