Using the Cluster Configuration (SCSI Only)For the SANnet II 200 SCSI array and the SANnet II 220 SCSI array, if you are using Microsoft Windows, SANscape can monitor shared SCSI storage. A cluster configuration must be set up with the appropriate hardware first, and it also requires Windows 2000 or 2003 Server and Microsoft Cluster Server (MSCS) software. Planning the Cluster Configuration Before you set up a cluster configuration, you must determine what type of configuration you want because it can make a difference in how you configure the storage initially. There are two main types of cluster configuration:
A minimum of three LUNs must be defined. This enables one small LUN to be established for quorum disk use and a large LUN to be used on each server in the cluster. The quorum disk maintains the cluster configuration data necessary to recover the cluster in the event of a server failure. Cluster Configuration Requirements When you are installing the MSCS software,
identify the disk to be used for the quorum disk, which maintains cluster
information. For an overview of the steps needed to set up an array in a cluster configuration with two host servers, see "To Set Up Cluster Configuration" in the SANscape User's Guide. |
