HP Matrix Operating Environment 7.0 Recovery Management User Guide

Glossary
CMS HP Systems Insight Manager (HP SIM) Central Management Server — A system in the management
domain that executes the HP SIM software. All central operations within HP SIM are initiated
from this system.
consistency group Consistency groups are an important property of asynchronous mode volumes. A consistency
group is a group of LUNs that need to be treated the same from the perspective of data consistency
(I/O ordering). A consistency group is equal to a device group in the Raid Manager configuration
file.
discovery A feature within a management application that finds and identifies network objects. In HP
management applications, discovery finds and identifies all the HP systems within a specified
network range.
DR Group (Disaster Recovery Group) The HP P6000 Continuous Access Software term for a Storage
Replication Group.
DR Protected (Disaster Recovery Protected) Logical servers that are managed by Matrix recovery management
are referred to as “DR Protected” logical servers.
HP Matrix OE
logical server
management
A component of the HP Matrix Operating Environment software that manages and automates
operations associated with logical servers, including resource provisioning, startup and shutdown.
HP SIM HP Systems Insight Manager
Job An automated, multi-step process associated with Matrix recovery management site role reversal
(either changing a Remote Site to a Local Site, or changing a Local Site to a Remote Site)
Local Site The set of managed nodes and corresponding CMS that your browser is interacting with.
logical servers Logical servers are management abstractions that simplify and optimize the provisioning,
management, and movement of servers - whether they are physical servers or a virtual machines.
Logical servers are managed by the Matrix OE visualization component of the HP Matrix Operating
Environment.
Maintenance Mode Maintenance Mode is used to test Recovery Groups at the Remote Site to ensure they will function
properly when an Activate... operation is performed.
planned failover A failover of all Recovery Groups from the Local Site to the Remote Site initiated in anticipation
of an imminent disaster or planned downtime at the Local Site.
power-up delay A Recovery Group configuration setting that determines the minimum time delay (in minutes)
between the power-up of any 2 logical servers in a Recovery Group. The actual time delay may
be more than the minimum time delay specified.
private A subnet that is not routed outside the data center and typically contains addresses only in the
192.x.x.x or 10.x.x.x address ranges. public A subnet that is accessible to the Internet and cannot
contain IP addresses in the 192.x.x.x or 10.x.x.x address ranges.
Recovery Group A pairing of one or more logical servers and a single Storage Replication Group. A Recovery
Group has a “recovery group start order” number associated with it. During a site failover,
Recovery Groups are failed over from the Local Site to the Remote Site in the order specified.
recovery group
start order
An optional number that specifies the order in which a Recovery Group is to be started during a
site failover. Recovery Groups without a start order number are started after all Recovery Groups
that have an associated start order number.
recovery logical
servers
Logical servers at the Remote Site that are included in a Recovery Group. They are associated
with logical servers at the Local Site that are included in the same Recovery Group. Normally
they are deactivated and disabled. They are enabled and activated upon site failover.
redundant SAN The duplication of components to prevent failure of the SAN solution.
Remote Site The site in the Matrix recovery management configuration that is not the ;Local Site.
remote site The site other than the 'local' site.
SAN A network (or subnetwork) that connects data storage devices with associated data servers. A
storage area network is typically part of an overall network of computing resources.
