Local and Multihost Disks in a Sun Cluster Environment
Two sets of storage arrays reside within a cluster: local disks and multihost
Local disks are
directly connected to a single node and hold the Solaris Operating System for each
disks are connected to more than one node and hold client application data and other
files that need to be accessed from multiple nodes.
For more conceptual information on multihost disks and local disks, see the Sun Cluster concepts documentation.
