Hitachi Command Suite 8 User Guide

							management clientA computer used to operate a graphical user interface client or a
command-line interface client.
master journal The primary, or main, journal volume. A master journal holds differentialdata on the primary replication system until the data is copied to the
restore journal (R-JNL) on the secondary system. See also restore journal.
N
NAS Network attached storage
NIC Network interface card
P
pair status Indicates the condition of a copy pair. A pair must have a specific status
for specific operations. When a pair operation completes, the status of the pair changes to a different status determined by the type of operation.
path A path from a storage system volume to a host group.
In this manual, the term "path" may mean a path, external path, or LUN
path without making distinctions among them.
pool volume (pool-VOL) A logical volume that is reserved for storing Copy-on-Write Snapshot dataor Dynamic Provisioning write data.
primary volume In a volume pair, the source volume that is copied to another volume
using the volume replication functionality of a storage system. The data on the P-VOL is duplicated synchronously or asynchronously on the
secondary volume (S-VOL).
properties file A file that defines aspects of the operating environment. The operatingenvironment can be modified by changing the appropriate properties file.Glossary461Hitachi Command Suite User Guide 
						

							R
RACF (Resource Access Control Function) Functionality for controlling user authentication and resource access on
the mainframe host.
RADIUS Remote Authentication Dial In User Service
RAID redundant array of independent disks
A collection of two or more disk drives that presents the image of a single
logical disk drive to the system. Part of the physical storage capacity is
used to store redundant information about user data stored on the
remainder of the storage capacity. In the event of a single device failure,
the data can be read or regenerated from the other disk drives.
RAID employs the technique of disk striping, which involves partitioning
each drive's storage space into units ranging from a sector (512 bytes) up
to several megabytes. The stripes of all the disks are interleaved and
addressed in order.
RAID level The type of RAID implementation. RAID levels include RAID 0, RAID 1,
RAID 2, RAID 3, RAID 4, RAID 5 and RAID 6.
recovery point objective In business continuity planning, the maximum tolerable period in whichdata can be lost from an IT service due to a major incident.
refresh To update the database using the most recent information.
remote control unit A storage system at a secondary, or remote, site that is configured toreceive remote I/O instructions from one or more storage systems at the
primary, or main, site. See also main control unit.
resource group A collection of resources that are grouped by one or more system
resource types.462GlossaryHitachi Command Suite User Guide 
						

							resource poolA type of resource group to which resources of a virtual storage machine
in a Virtual Storage Platform G1000 system belong, if those resources
have not been added to another resource group. There are two types of
resource pools: the resource pool on the default virtual storage machine
and the resource pool that is created automatically for each virtual
storage machine that you create on a VSP G1000 system.
restore journal The secondary, or remote, journal volume. A restore journal holds
differential data on the secondary replication system until the data is
copied to the secondary volume (S-VOL). See also master journal (M-
JNL).
role Permissions that are assigned to users in a user group to control access to
resources in a resource group. Resource groups can be assigned to
different user groups with different roles.
RPO See recovery point objective.
S
SAN storage area network. A network of shared storage devices that contain
disks for storing data.
SAS (Serial Attached SCSI) A replacement for Fibre Channel drives in high performance applications.
See SCSI.
SATA Serial Advanced Technology Attachment. A computer bus technologyprimarily designed for the transfer of data to and from hard disks and
optical drives. SATA is the evolution of the legacy Advanced Technology
Attachment (ATA) interface from a parallel bus to serial connection
architecture.
SCSI (Small Computer System Interface) Standards that define I/O buses primarily intended for connecting storage
systems and devices to hosts through host bus adapters.Glossary463Hitachi Command Suite User Guide 
						

							secondary volumeAfter a backup, the volume in a copy pair that is the copy of the original
data on the primary volume (P-VOL). Recurring differential data updates
keep the data in the S-VOL consistent with the data in the P-VOL.
Secure Sockets Layer (SSL) A common protocol for managing the security of message transmissionover the Internet.
Two SSL-enabled peers use their private and public keys to establish a secure communication session, with each peer encrypting transmitted
data with a randomly generated and agreed-upon symmetric key.
SLPR Storage Local Partition
SMU System Management Unit
SNMP Simple Network Management Protocol
SSD Solid-state drive
storage pool A collection of system drives or the logical container of a file system.Storage pools are created in the Hitachi NAS Platform family of products. Storage pools are also called  spans.
system drive The basic (logical) storage element that is managed by the Hitachi NASPlatform family of products. A system drive is equivalent to a storage
system volume.
T
tiered storage A layered structure of performance levels, or tiers, that matches dataaccess requirements with the appropriate performance tiers.464GlossaryHitachi Command Suite User Guide 
						

							U
unallocated volume A volume (LDEV) for which no host paths are assigned.
URL Uniform Resource Locator
user group A collection of users who have access to the same resources and have thesame permissions for those resources. Permissions for users are
determined by the user groups to which they belong. Users and resource
groups can be assigned to multiple user groups.
V
virtual storage machine A virtual storage system that you create on a VSP G1000 system thatallows multiple resource groups to be treated as a single device.
VOLSER The label of a volume assigned by the mainframe host.
volume (vol or VOL) A name for the logical device (LDEV), or logical unit (LU), or concatenatedLDEVs, that are created in a storage system that have been defined to
one or more hosts as a single data storage unit.
W
web client An application that is used on a client machine to access a server on
which management software is installed. A web client contains two parts:
dynamic web pages and the web browser.
WWN nickname World wide name nickname. A name that is set for the WWN of an HBAthat identifies which HBA to operate on. The WWN nickname easilyidentifies accessible HBAs that are registered in a host group. You can
display a list of WWN nicknames to confirm target HBAs for a host while
you edit LUN paths during or after volume allocation or when you replace
an HBA.Glossary465Hitachi Command Suite User Guide
