Dell SE500W manual Configuring and Managing Virtual Disks

Page 45

See the PERC RAID adapter documentation for more information about setting the SCSI host adapter ID number.

NOTICE: If you replace a PERC RAID adapter, you must set the appropriate SCSI ID before you connect the SCSI cables to the shared storage. See "Maintaining Your Cluster" for more information.

Configuring and Managing Virtual Disks

The hard drives in the shared storage system must be set up for clustering. The first step is to configure the RAID levels that you will be using in your cluster. For instructions about setting up a RAID array, see the PERC RAID adapter documentation and the Dell OpenManage Array Manager or Dell OMSM documentation.

All virtual disks, especially if they are used for the quorum resource, should incorporate the appropriate RAID level to ensure high availability. See "Creating 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 availability required for the quorum resource. See the documentation for your storage system for more information about setting up RAID levels for the system.

In a cluster configuration, if multiple NTFS partitions are created on a single virtual disk, these partitions will fail over together. If you plan to run cluster-aware applications on each cluster node, you must create at least two separate virtual disks to ensure that the applications can fail over independently.

"Naming and Formatting Drives on the Shared Storage System" describes how to assign drive letters to the shared hard drives in a cluster installation. For instructions on partitioning and formatting the shared storage system’s hard drives, see the appropriate operating system documentation and the PERC RAID adapter documentation.

Windows 2000 and Windows Server 2003 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.

Naming and Formatting Drives on the Shared Storage System

After the virtual disks are created, write the disk signature, assign drive letters to the virtual disks, and then format the drives as NTFS drives. Format the drives and assign drive letters from only one cluster node.

NOTICE: Accessing the hard drives from multiple cluster nodes may corrupt the file system.
