1 Overview
This chapter provides an overview of XP Replication Monitor software for first-time users and for
those considering installing XP Replication Monitor software. It contains the following sections:
• About XP Replication Monitor software (section 1-1 )
• System configuration examples (section 1-2 )
1-1 About XP Replication Monitor software
XP Replication Monitor software supports management operations for storage a dministrators. XP
Replication Monitor software can be used to check the configuration and change the status of copy
pairs created using the volume replication functions of HP StorageWorks XP disk array subsystem
and Storage Virtualization Systems.
1-1-1 XP Replication Monitor features
With the rapidly increasing volume of data in corporate information systems, the use of storage
subsystems has evolved from standalone storage subsystems in a single location to linked storage
subsystems at multiple data centers. Additionally, to prevent loss of data and stoppage of
application services due to accidents or disasters, more environments are being equipped for
disaster recovery. Linking remote data centers can protect data and enable system recovery.
Managing large and remote systems requires understanding the configuration of multiple cop y pairs
across storage subsystems and monitoring copy pair status. You must also understand the
configuration of the hosts that are connected to the storage subsystems, and you must be abl e to
quickly isolate the affected area when a failure occurs.
The following capabilities of XP Replication Monitor software help you manage complex systems:
• Ability to check copy pair and copy group configurations
XP Replication Monitor software allows you to check the configuration of copy pairs across
multiple storage subsystems, from the viewpoints of hosts, storage subsystems, and copy pair
configuration definition.
XP Replication Monitor software also allows you to view a list of linked copy pairs in complex
copy pair configurations, such as multitarget configurations (in which one volume is copied to
multiple volumes) and cascade configurations (in which volume copy relationships span
multiple levels).
• Ability to check copy pair and copy group status
XP Replication Monitor software allows you to view the pair statuses for copy pairs and copy
groups. You can check the status by using the six general classifications defined in XP
Replication Monitor (error, suspend, copying, sync, simplex, and unknown), or by using the
detailed classifications that are based on the pair statuses used in Device Manager, XP RAID
Manager, and XP for Business Continuity Manager Software. In addition to the pair status, you
can check the copy progress.
You can also obtain and view the summary copy pair status in a higher-level unit that includes
a copy group or copy pair. For example, you can obtain the summary copy pair status in a host
or storage subsystem. This allows you to isolate failures beginning with a general view of copy
pair statuses throughout the system, and successively narrowing down the view to the location
where a problem occurred.
• Ability to monitor and notify users of copy pair and copy group status
By specifying alerts for specific copy pairs, you can set up XP Replication Monitor software to
notify users of copy pair status changes that occur (for example, because of an error). You can
15
inform users by e-mail or by way of SNMP traps. You can also use the Dashboard (a pane of
the XP Replication Monitor window that displays important information) to check the latest
alerts and display alert history in list form.
About this guide
• Ability to acquire transfer delay statuses related to volume replication functions
When you use an asynchronous remote copy product (XP Continuous Access Asynchronous
Software or XP Continuous Access Journal Software), and a primary volume is updated, there
is a time lag (transfer delay) before the secondary volume is updated. With XP Replication
Monitor software, you can check the transfer delay time and the usage of the storage
subsystem cache area (side file and journal volume) during copying. This allows you to
proactively predict and take action against problems, such as transfer performance
degradation due to insufficient network bandwidth and pair blockage due to cache overflow.
• Ability to provide centralized management of heterogeneous systems
You can use XP Replication Monitor to centrally manage different types of storage subsystems
(including XP24000/XP20000) and hosts (including Windows systems, Solaris systems, and
mainframe systems) from a single window.
This means that you do not need to use different tools nor learn separate operations for each
system.
Figure 1-1 shows the XP Replication Monitor window layout.

1-1-2 Target users
XP Replication Monitor software is for storage administrators and other users who manage sto rage
subsystem volume replication functions. More specifically, it is for users who are in charge of the
following operations:
• Troubleshooting volume replication functions
○ You can set alerts and automate monitoring for copy pair errors.
○ You can use different views and check copy pair statuses from various viewpoints, which
helps you isolate the location and affected scope of errors
• Monitoring volume replication function performance
○ You can check performance information related to volume replication, such as the transfer
delay status of remote copies. Also, by exporting to CSV files the logs that contain
performance information collected over time, you can use performance information to
create analyses and reports.
17
○ You can automatically monitor performance information against failures by presetting alerts.
• Using volume replication functions to create backup systems
○ You can view copy pair configuration and confirm that the copy pairs are configured as
intended.
• Using volume replication functions to operate and maintain backups
○ You can specify copy pairs and copy pair groups, and manually change a pair status
(splitting and resynchronizing).
○ You can view pair configuration and pair status and make sure there are no abnormalities.
○ You can check the alert history and make sure that changes in pair status are carried out
as planned.
○ You can check the copy progress by displaying the copy progress rate.
1-1-3 Important terms
This section explains key terms and concepts for using XP Replication Monitor software. For
additional definitions, see the
• LDEV (Logical DEVice)
A volume created in a storage subsystem. This is called a logical device.
• LU (Logical Unit)
A volume created in a storage subsystem. This is also called a logical unit.
When an LDEV volume created in a storage subsystem is used from an open system host, it is
treated as an LU.
• LUN (Logical Unit Number)
A management number assigned to an LU in a storage subsystem.
A LUN is assigned to identify an LU for the port in the storage system to which the LU is
connected, either by port or by host group assigned to the port. An open system host uses a
LUN to access a particular LU.
• DEVN (DEVice Number)
A device number that is assigned to identify an LDEV when it is being used by a mainframe
system.
A DEVN is expressed as a four-digit hexadecimal number.
• CU (Control Unit)
A virtual control unit created in a storage subsystem. This is also called a CU image.
The LDEVs created in a storage subsystem are connected to a single CU, and this numbe r is
assigned to each CU for identifying the LDEVs. Therefore, volumes (LDEVs) in a storage
subsystem are specified by the CU number (CU#) and LDEV number.
• Storage subsystem volume replication functionality
A general name for functionality (such as XP Business Copy Software and XP Continuous
Access Software) that provides high-speed replication of volumes in a storage subsystem. The
functionality provided by the storage subsystem creates volume replicas quickly, without going
through the LAN.
• Primary volume (P-VOL)
The volume from which replication is performed, when the volume replication functionality of
the storage subsystem performs copying to another volume.
• Secondary volume (S-VOL)
The volume to which replication is performed, when the volume replication functionality of the
storage subsystem copies from the primary volume.
About this guide
Glossary.
18
About this guide
• Secondary-primary volume (SP-VOL)
A volume placed between the primary volume and secondary volume, when a cascade
configuration is used by the volume replication functionality of the storage subsystem. This
indicates the secondary volume for an upper copy pair, and the primary volume for a lower
copy pair.
• Copy pair
A pairing of a primary volume and a secondary volume, linked by the volume replication
functionality of the storage subsystem. This is also called a pair volume. In this manual, copy
pair may be written simply as pair.
• Copy group
A group containing multiple copy pairs. A copy group allows operations such as pair status
changes to be applied to multiple copy pairs.
• Prefix
The name of the prefix of the copy group definition file (prefix.GRP.copy-group-id)
created by XP for Business Continuity Manager Software. XP Replication Monitor software
uses the prefix as a unique name to identify copy group definition files created by XP for
Business Continuity Manager Software.
1-2 System configuration examples
XP Replication Monitor software works by linking with programs such as Device Manager or XP for
Business Continuity Manager Software. This section provides examples of typical system
configurations that include XP Replication Monitor software.
An XP Replication Monitor system can be configured in ways other than those described in this
section. Also, although this section describes configuration examples of an open system host and a
mainframe system host separately, you can use XP Replication Monitor software in mixed
environments that include both of these host types.
For details about specific system configurations that support XP Replication Monitor software, see
the HP StorageWorks XP Replication Monitor software installation and configuration guide.
1-2-1 Open system configuration example
Figure 1-2 shows an example of a system configuration when the host using the storage subsystem
is an open system (Windows, AIX, HP-UX, Solaris, or Linux).
19
About this guide
Figure 1-2 Example system configuration for an open system
The following explains each of the configuration elements.
Management client
The machine on which the web client for XP Replication Monitor software runs. This machine
issues instructions to XP Replication Monitor software on the management server to perform
the main functions, such as viewing pair configurations, and to monitor and change pair status.
Since the web client for XP Replication Monitor software runs in a web browser, no application
needs to be installed on the management client.
Management server
The machine on which the XP Replication Monitor software server and its prerequisite
program, the Device Manager server, are installed. The management server requests
configuration information or pair status information from each host or pair management server
and provides the information to the management client.
Pair management server
A server that is used to collect system information, such as the copy pair status and the
transfer delay state of remote copies. You install an XP Replication Monitor agent, a Device
Manager agent, and an XP RAID Manager on this server.
20
When you install an XP Replication Monitor agent, a Device Manager agent, and XP RAID
Manager on a host, you can use the host as a pair management server. However, due to the
load imposed on the host by the collection of system information, HP recommends that you set
up the pair management server independently, as shown in
Host (application server)
A machine on which application programs are installed. The host uses a storage subsystem as
an external storage device. By installing a Device Manager agent on the hosts, you can use XP
Replication Monitor software to view such information as the host's IP address, mount point,
and linked copy groups.
Storage subsystem
An external storage device (HP StorageWorks XP disk array subsystem) connected to a host.
Normally, volumes in a storage subsystem are set up as several copy pairs using a volume
replication function (for example, XP Business Copy Software or XP Continuous Access
Software). The main function of XP Replication Monitor software is to display the configuration
and copy status of these copy pairs.
Storage subsystem information is provided to XP Replication Monitor software in the following
two ways:
Figure 1-2.
About this guide
○ The management server collects information directly from the storage subsystems.
○ The pair management server collects the storage subsystem information and then transfers
it to the management server.
1-2-2 Mainframe system configuration example
Figure 1-3 shows an example of a system configuration when the host using the storage subsystem
is a mainframe system (OS/390 or z/OS).
21
About this guide
Figure 1-3 Example system configuration for a mainframe system
The following explains each of the configuration elements.
Management client
The machine on which the web client for XP Replication Monitor software runs. This machine
issues instructions to XP Replication Monitor software on the management server to perform
the main functions of XP Replication Monitor software, such as viewing pair configurations and
to monitor and change pair status. Since the web client for XP Replication Monitor software
runs in a web browser, no application needs to be installed on the management client.
Management server
The machine on which the XP Replication Monitor server and its prerequisite program, the
Device Manager server, are installed. The management server requests storage subsystem
information from the XP for Business Continuity Manager Software on the host and provides
the information collected to the management client.
Host (application server)
A machine on which application programs are installed. The host uses the storage subsystem
as an external storage device and runs the application programs.
In response to management server requests, the mainframe system host also plays a role
similar to that of a pair management server in an open system, in that it collects information on
itself and its storage subsystems and provides this information to the management server.
Because of this, mainframe system hosts are sometimes called pair management servers.
XP for Business Continuity Manager Software must be installed on the host.
22
Storage subsystem
An external storage device (HP StorageWorks XP disk array subsystem) connected to a host.
Normally, several copy pairs of the volumes in a storage subsystem are set up using volume
replication functionality (for example, XP Business Copy Software or XP Continuous Access
Software). The main function of XP Replication Monitor software is to display the configuration
and copy status of these copy pairs.
The pair management server collects the storage subsystem and then transfers it to XP
Replication Monitor software in the following two ways:
About this guide
○ The management server collects information directly from the storage subsystems.
○ The pair management server collects the storage subsystem information and then transfers
it to the management server.
Only XP24000/XP20000, XP12000/XP10000/SVS200, and XP1024/XP128 series systems can
be connected to a mainframe system host.

2-1 Displaying copy pair status and
configurations
You can use XP Replication Monitor software to view the status and configurations of all copy pairs
managed by Device Manager and XP for Business Continuity Manager Software, as viewed from
hosts, storage subsystems, or pair configurations.
You can use XP Replication Monitor software to manage copy groups as well as copy pairs. XP
Replication Monitor software can display a list of all the copy pairs included in a copy group,
24
enabling you to quickly check the status and configurations of all copy pairs included in a copy
group.
Similarly, XP Replication Monitor software can display a list of managed copy pairs and copy
groups, even when they have a cascade configuration, enabling you to quickly check the status and
configurations of all copy pairs and copy groups that are associated in a cascade configuration.
This section explains how copy pair status and configurations are displayed.
XP Replication Monitor functions
2-1-1 Displaying copy pair status and configurations by view
XP Replication Monitor software helps you identify and analyze errors by displaying the status and
configurations of copy pairs in the following views:
• Hosts view
• Subsystems view
• Pair configurations view
The following sections describe the features of these three views.
For details about how to check the copy pair status using a view, see section
how to check copy pair configurations using a view, see section
2-1-1-1 Hosts view
The hosts view is a display format used to check the status and configurations of copy pairs from a
list of hosts (application servers). In the same view, you can check the status and configurations of
specified copy pairs that have been set in a cascade configuration. You can also check the status
and configuration of each copy group.
The hosts view facilitates checking for those operating and managing hosts, such as system
administrators.
