| 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 |
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 |
| the GS explorer, the SNMP explorer, and the HBA |
| 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. |
