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.
It is recommended that you create 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
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.
NOTE: It is recommended 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 availability required for the quorum resource. See the documentation for your storage system for more information about setting up RAID levels for the system.
