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.
