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.
