PRIMECLUSTER Global Disk Services Configuration and Administration Guide 4.2 (Linux)

H.1 What Is Shared Disk Resource Registration?

In a cluster system, before configuring GDS classes, groups, and volumes, it is required to register shared disk units with the PRIMECLUSTER resource database. The resource database is used to manage information of node and shared disk unit physical connection configuration (how each shared disk unit is connected to each node). GDS recognizes shared disk unit physical connection configuration based on information in the resource database to manage shared disk units.
