Symantec 5.1 manual accessibility from specified SAN-attached hosts

	CommandCentral Glossary 43
	associated with the LUN (the access path) between that AddrUnit and an array
	port to which it is bound. The access control list for a LUN contains the World
	Wide Name of each HBA port that is allowed to access that LUN within the array.
LUN Query Tool	A CommandCentral Storage tool that helps you find LUNs on your storage network
	that match one or more properties, such as device vendor, storage type, capacity,
	configuration, cost, and location. The LUN Query Tool can further refine the
	search for LUNs based on the groups to which they are assigned or based on their
	accessibility from specified SAN-attached hosts.
LUN storage	Configured storage that has been apportioned into addressable units (LUNs) and
	is ready to be allocated to hosts. Also called addressable storage. Contrast with
	available storage.
managed host	The part of CommandCentral Storage that assists the Management Server in
	discovering all of the resources in the storage network. The managed host is
	connected to the Management Server and consists of several explorers—such as
	the GS explorer, the SNMP explorer, and the HBA explorer—that are also used by
	the Management Server. Although the managed host uses a modified form of the
	Hardware Abstraction Layer process used in the Management Server, it is not
	itself a server. Prior to CommandCentral Storage version 5.x, the managed host
	was known as the Agent.

managed virtual host A CommandCentral Storage managed host that is installed on a guest operating

	system on a virtual machine. See virtual machine.
masking	See LUN masking.
MGEX	See GS explorer.
mirroring	A form of storage redundancy in which two or more identical copies of data are
	maintained on separate volumes. (Each duplicate copy is known as a mirror.) Also
	RAID Level 1.
multipathing	Multiple physical access paths to a disk connected to a host system. Any software
	residing on the host (for example, the DMP driver) that hides multiple physical
	access paths from the user is said to provide multipathing functionality. See also
	Dynamic Multipathing (DMP).

NetApp unified storage A class of storage devices in which hosts and users gain access to storage through a specialized set of protocols. The NetApp unified storage system handles both SAN and NAS transactions and makes the specifics of each networked storage model (Fibre Channel SAN, iSCSI SAN, and NAS) transparent to the user.

NetBackup	See Veritas NetBackup.
node	An object in a network. In Veritas Cluster Server, node refers specifically to one
	of any number of hosts in a cluster. See also object.
