1 Overview
This chapter provides an overview of the HP P6000 Command View software suite.
IMPORTANT: General references to HP P6000 Command View can also refer to earlier versions
of HP Command View EVA. HP P6000 Command View supports all HP P6000 EVA models except
for HP EVA3000/5000.
Prerequisites
HP P6000 Command View must be installed on at least one of the following:
• HP 4400 Enterprise Virtual Array (EVA4400), P6300 Enterprise Virtual Array (P6300 EVA),
P6350 Enterprise Virtual Array (P6350 EVA), P6500 Enterprise Virtual Array (P6500 EVA),
or P6550 Enterprise Virtual Array (P6550 EVA) management module
• General-purpose server
• Dedicated management server
• HP X1000/X3000 Network Storage Systems and Gateways
Earlier versions of HP P6000 Command View were required to be installed on a management
server. HP P6000 Command View EVA and Command View EVA 8.1 or later is installed on the
management module (9.4 or later on the P63x0/P65x0 EVAs), eliminating the need for a separate
management server. Other arrays continue to require a management server.
HP P6000 Command View Suite software
Use the HP P6000 Command View Suite software to configure, manage, and monitor HP's family
of advanced, enterprise storage arrays. The software suite includes:
• HP P6000 Command View—Use the graphical user interface for initial configuration, storage
provisioning, and ongoing storage system management and monitoring.
• HP Storage System Scripting Utility—Use the command line interface to script and run repetitive
and complex configuration tasks. See HP Storage Scripting Utility Reference for more
information.
• HP P6000 Performance Data Collector—Use this tool to monitor array performance (server-based
management only).
• Storage Management Initiative Specification for P6000 Enterprise Virtual Array (SMI-S
EVA)—Install SMI-S EVA on a management server to provide a common management interface
in a server-based management environment. It is a standard management interface developed
by SNIA to ease the management burden in multi-vendor SAN environments.
• HP Management Integration Framework (MIF)—Use the interface provided by the HP MIF
software to provide storage-related security for HP P6000 Command View.
• HP P6000 Performance Advisor—Use this tool to monitor HP P6000 storage systems and
collect metrics to analyze performance (server-based management only).
• HP EVA to 3PAR StoreServ Online Import — Use this software to migrate data from an HP
EVA storage system to an HP 3PAR storage system (server-based management only).
• HP P6000 SmartStart—You can use this DVD-based wizard to install HP P6000 Command
View. The wizard also helps you configure, provision and mount storage volumes on Windows
and Linux servers.

HP P6000 Command View features
HP P6000 Command View enables you to:
• Manage storage security and passwords
• License storage systems
• Provision storage to hosts
• Replicate storage using HP P6000 Business Copy and HP P6000 Continuous Access
• Maintain and manage storage systems
• Monitor storage system events
• Monitor performance data
Server-based and array-based management
HP P6000 Command View is available in server-based and array-based versions.
Server-based management. The server-based version of HP P6000 Command View is installed on
a management server which is connected to one or more HP EVA storage systems. See
Figure 1 (page 9). All components of the software suite (HP P6000 Command View, HP P6000
Performance Data Collector, HP Storage System Scripting Utility, HP P6000 Performance Advisor,
and SMI-S EVA) can be installed on the server. Server-based management can be used with all
P6000 storage arrays.
IMPORTANT: HP P6000 Command View relies on the IP address assigned to the server for
management lock verification. Therefore, the HP P6000 Command View server must have a unique
IP address to ensure proper control locking.

6. HP EVA storage systems3. Management server
Figure 1 (page 9) shows multiple HP EVA storage arrays and hosts in a Fibre Channel SAN being
managed by one instance of server-based HP P6000 Command View on a management server.
The management server is also connected to a LAN so that users and administrators can browse
to the HP P6000 Command View interface.
HP P6000 Command View does not require hosts to be connected to the LAN. However, a LAN
connection can be a requirement of other HP server-based applications.
Array-based management. The array-based version of HP P6000 Command View comes
factory-installed on HP EVA4400, P6300 EVA, P6350 EVA, P6500 EVA, and P6550 EVA storage
systems. With these storage arrays, a separate management server is not required. Only one
component of the software suite, HP P6000 Command View itself, is installed on a storage array.
The other components of the software suite can be installed on a separate server. See Figure 2 (page
10).

Figure 2 (page 10) shows multiple HP EVA4400 storage systems and hosts in a Fibre Channel
SAN. In this case, each EVA4400 storage system has a factory-installed instance of array-based
HP P6000 Command View. Each HP EVA4400 storage system is also connected to a LAN so that
users and administrators can browse to each HP P6000 Command View interface.
HP P6000 Command View does not require hosts to be connected to the LAN. However, a LAN
connection can be a requirement of other HP server-based applications.
HP EVA4400, P6300 EVA, P6350 EVA, P6500 EVA, and P6550 EVA storage systems can also
be managed from an instance of server-based HP P6000 Command View. For example, to configure
an HP EVA4400 for remote replication, you must use server-based management. A feature in both
versions of HP P6000 Command View allows HP EVAs to be selectively managed by more than
one instance of HP P6000 Command View. However, only one instance can manage an EVA at
a time. The HP P6000 Command View server must take control of the EVA away from all other
instances before issuing management commands to the EVA.
HP Management Integration Framework
Each instance of HP P6000 Command View and HP P6000 Performance Advisor includes HP MIF
software which provides HP storage applications with:
• Single Pane of Glass interface
• Management Group capabilities
• Enhanced single sign-on capabilities
HP MIF software also includes the following interfaces for administrators:
• Security interface
• Configuration interface
• Command line interface
10 Overview
For more information, see the online help or the HP Management Integration Framework
Administrator Guide and the HP Management Integration Framework Maintenance and Service
Guide.
User interface
HP P6000 Command View uses a SPoG interface, which can display multiple HP P6000 storage
software applications in a single browser window. When multiple instances of server-based or
array-based HP P6000 Command View are in the same Management Group, the SPoG interface
displays all of the storage systems managed by those instances.
NOTE: If you add more than one array-based management instance to a Management Group,
HP recommends that you assign a unique name to each instance.
The SPoG interface has two points of view:
• The storage systems point of view is the primary means of viewing and managing the storage
systems in a management group. If you have Performance Advisor installed, you can view
storage system performance information by clicking the Performance tab.
• The settings point of view is the primary means of viewing and changing options in HP P6000
Command View and HP P6000 Performance Advisor.
For information about HP P6000 Performance Advisor, see the HP P6000 Performance Advisor
User Guide or online help.
NOTE: HP P6000 Command View does not support the internationalization and localization
(i18n) format for object names and comments.
The following illustrations show examples of the HP P6000 Command View interface.
User interface 11
Point of view selectors
Located on the lower left of the window, these selectors enable you to select the point of view that
is displayed. The selector for the active point of view is colored orange.
• When the storage systems point of view is selected, all of the managed and initialized storage
systems in the Management Group are displayed in an expandable tree in the navigation
pane.
• When the settings point of view is selected, storage applications and folders of unmanaged
and uninitialized storage systems are displayed in the navigation pane. In the settings point
of view you can change storage application settings, assume management control of
unmanaged storage systems, and initialize storage systems.

Internet Protocol support
The HP P6000 Command View Suite is designed for use with internet protocols as follows:
• Server-based versions 8.0.2 and later—IPv4, IPv6, and mixed IPv4/IPv6 networks
• Server-based versions earlier than 8.0.2—IPv4 networks only
• Array-based versions 10.1 and later—IPv4, IPv6, USGv6, and mixed IPv4/IPv6/USGv6
networks
• Array-based versions 9.2 and later—IPv4, IPv6, and mixed IPv4/IPv6 networks
• Array-based versions earlier than 9.2—IPv4 networks only
• Internet Explorer 8.0 and later, or Mozilla FireFox 4.0 and later is required to access the HP
P6000 Command View Suite using the IPv6 address.
• For server-based configurations, if IPv4 and IPv6 are installed on a single system, HP P6000
Command View starts on the IPv4 address by default. If you want to start HP P6000 Command
View on a specific address, you must add the address entry under the webserver section
of the cveva.cfg configuration file. For example, to start HP P6000 Command View on
IPv6, enter address 0::0 under the webserver section of cveva.cfg.
• Using the IPv6 link local address to run the management server can result in connectivity issues.
• For server-based systems, the management server is available on either the IPv4 or the IPv6
address only.
NOTE: HP P6000 Performance Data Collector has the same behavior with IPv6 as HP P6000
Command View. To start HP P6000 Performance Data Collector on a specific IPv6 address, you
must add the evapdcs.address entry in the evaperf.conf file and specify the address.
IP address formats
IP addresses in IPv6 have a different format than IPv4.
• IPv6 IP addresses are generally shown in eight groups of four hexadecimal digits, separated
by colons, for example, 2001:0db8:85a3:08d3:1319:8a2e:0370:7334.
• IPv4 IP address are generally shown in decimal notation, separated by dots (periods), for
example: 192.0.2.235.
• IPv6 IP addresses with port numbers are enclosed in brackets to avoid confusion with port
numbers, for example:
https://[2001:0db8:85a3:08d3:1319:8a2e:0370:7344]:443/.
• IPv4 addresses with port number do not use brackets.
Internet Protocol support 15
2 Managing security and passwords
This chapter explains how to use HP P6000 Command View to manage your storage environment.
NOTE: See the HP P6000 Command View online help for detailed procedures related to managing
your storage environment. When you install HP P6000 Command View, the initial folders are
Virtual Disks, Hosts, Disk Groups, Data Replication, and Hardware. You can create subfolders to
further organize and manage your hosts and virtual disks.
Server-based HP P6000 Command View security groups
Installation of HP P6000 Command View on a management server automatically creates the
following Windows security groups on the server:
• HP Storage Admins group—Members have view and manage capabilities.
• HP Storage Users group—Members have view capability only.
You can set a local or domain user to have the permissions of either of these groups.
To use HP P6000 Command View or SMI-S EVA, a user with Windows administrator privileges
for the management server must create user accounts and assign them to the appropriate security
group.
Array-based HP P6000 Command View security groups
Array-based HP P6000 Command View in each HP EVA management module has one administrator
and one user account. Login credentials are set in the EVA management module and can be
configured using the HP P6000 Control Panel. For more information, see the HP P6000 Control
Panel User Guide.
Password protection for storage systems
Individual HP EVA storage systems can be password protected. When a storage system is not
password protected, all instances of server-based HP P6000 Command View in the SAN fabric
can manage the storage system. When a storage system is password protected, only instances of
server-based HP P6000 Command View that have been enabled for access can manage the
storage system.
IMPORTANT: HP recommends that you use passwords to protect your HP storage systems.
Password protection is optional but strongly recommended, especially for SAN fabrics that include
multiple instances of server-based HP P6000 Command View.
• For most EVA storage systems, password protection is set using the Operator Control Panel
(OCP) on the storage system controllers. See the HP Enterprise Virtual Array User Guide.
• For HP EVA4400, P6300 EVA, P6350 EVA, P6500 EVA, and P6550 EVA storage systems,
password protection is set using the HP P6000 Control Panel. See the HP P6000 Control
Panel User Guide or the HP P6000 Control Panel online help.
IMPORTANT: If your storage system is managed by an instance of server-based HP P6000
Command View, HP strongly recommends that you store or update the password in HP P6000
Command View immediately after creating or changing the password on the storage system.
Password formats
• Passwords are case sensitive and can include 8 to 16 characters.
• The letters A–Z in upper or lower case are allowed.
16 Managing security and passwords
• The following numeric characters are allowed: 0 1 2 3 4 5 6 7 8 9
• The following special characters are allowed: ! " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ ] ^
_ { | }
Enabling management of a password-protected storage system
Use this procedure to enable management of a password-protected storage system from an instance
of server-based HP P6000 Command View.
Considerations
• You only need to perform this procedure if an instance of HP P6000 Command View on a
management server is not enabled to manage a password-protected storage system and you
want it to.
• If you have multiple management servers, you must perform this procedure with each instance
of HP P6000 Command View that you want to manage the password-protected storage system.
• This procedure does not create storage system passwords. Storage system passwords are
created by using an OCP or an HP P6000 Control Panel.
To enable HP P6000 Command View to manage a password-protected storage system from the
settings point of view:
1. In the session pane, click Management Options.
The Management Options window opens.
2. Select Manage storage system password access.
The Storage System Password Access window opens.

Storage systems that do not have a Command View-enabled password are listed.
5. Enter and confirm the storage system password.
6. Click Enable password.
The Enable password access dialog box opens.
7. Click OK.
A status window opens, indicating success or failure.
Disabling management of a password-protected storage system
Use this procedure to disable management of a password-protected storage system from an instance
of server-based HP P6000 Command View.
Considerations
• You only need to perform this procedure if you no longer want to manage a password-protected
storage system from an instance of HP P6000 Command View on a management server.
• If you have multiple management servers, you must perform this procedure with each instance
of HP P6000 Command View that you no longer want to manage the password-protected
storage system.
• This procedure does not remove or clear a password from the storage system itself. Storage
system passwords can only be removed or cleared from an OCP or an HP P6000 Control
Panel.

The password for an HP EVA4400, P6300 EVA, P6350 EVA, P6500 EVA, or P6550 EVA affects
access by external applications such as server-based HP P6000 Command View. It does not affect
access by the instance of array-based HP P6000 Command View that is internally installed on the
storage system.
Reestablishing communication with a password-protected storage system
A communication problem between an instance of server-based HP P6000 Command View and
a password-protected storage system can be caused when the stored password in HP P6000
Command View does not match the password that is set on a storage system. This can occur when:
• The password on a storage system has been changed.
• Controller software on a storage system has been updated to a newer version.
If you believe that a password mismatch is causing a communication problem with a storage
system, proceed as follows to synchronize the passwords.
1. In HP P6000 Command View, clear the stored password for the effected storage system. See
“Disabling management of a password-protected storage system” (page 17).
2. On the affected storage system, clear the password using the operator control panel (OCP).
See the user guide for your storage system.
3. On the management server, stop and then restart the HP P6000 Command View service.
18 Managing security and passwords
4. On the affected storage system, enter the new password using the OCP. See the user guide
for your storage system.
5. In HP P6000 Command View, store the new password for the affected storage system. See
“Enabling management of a password-protected storage system” (page 17).

3 Licensing HP P6000 EVA storage systems
Licenses to use and license keys
License types
The following types of licenses to use (LTUs) are available for HP P6000 EVA storage systems:
• HP P6000 Command View LTUs. These LTUs are required to manage a given storage system
with HP P6000 Command View.
Each HP P6000 storage system must be licensed with the appropriate HP P6000 Command
View LTUs to be in compliance with the End User License Agreement.
• HP MPX200 LTUs. These LTUs provide the ability to interconnect SANs via a LAN/WAN,
connect an FC device to a SAN over a LAN/WAN, or migrate the data between source and
destination arrays. The LTUs are installed on the MPX200 controller.
• HP P6000 Business Copy LTUs. These LTUs enable the use of optional local replication features,
such as snapshot, snapclone, and mirrorclone.
• HP P6000 Continuous Access LTUs. These LTUs enable the use of optional remote replication
features.
• HP P6000 Performance Advisor LTU. These LTUs allow you to monitor and analyze performance
of P6000 storage systems.
• Thin provisioning LTU. This LTU enables the thin provisioning feature.
• DC-Management LTU. This LTU enables the HP Dynamic Capacity Management feature.
NOTE: For the P6300/P6350/P6500/P6550 EVAs, the license keys for HP Dynamic Capacity
Management and thin provisioning are included with the HP P6000 Command View License
Entitlement.
Instant-on licenses
You can use the factory-installed instant-on license key to immediately start using the features with
the exception of HP Dynamic Capacity Management and thin provisioning. The instant-on key is
valid for all storage systems managed by an HP P6000 Command View server and enables HP
P6000 Command View, HP P6000 Business Copy, and HP P6000 Continuous Access with unlimited
capacity for 60 days from the first use. Upon expiration of the instant-on license key, these features
will be disabled. Your data is preserved and you can continue to use the storage system but cannot
create new resources. To continue using the features, you must obtain a permanent license key.
Permanent licenses
• Licenses are available in various capacities to support the maximum capacity of the storage
system. Storage system-upgrade licenses are also available.
• You can enter a license key before or after initializing the storage system. When a license
key is installed, the license immediately takes effect.
• HP P6000 Command View, HP P6000 Business Copy, HP P6000 Performance Advisor, and
HP P6000 Continuous Access LTUs are locked to a storage system and are not transferable.
• HP thin provisioning LTUs are model-locked.
When you install a permanent license, the temporary instant-on license no longer appears in the
license list.

Upgrading an EVA storage system requires a Model Upgrade license. Model Upgrade licenses
are effective only if there is a base permanent license for the lower version of controller. During
installation, the base permanent license is validated and if one is not found, a warning message
Licenses to use and license keys 21
displays to inform you that the upgrade license is not in effect because there is no permanent
unlimited license.

4 Provisioning storage
Provisioning is the industry-standard term for providing networked storage to application servers.
With HP P6000 EVA storage systems, provisioning includes the following general steps:
1. Creating one or more disk groups on a storage system.
2. Creating virtual disks within disk groups and assigning attributes, such as size and redundancy
level.
3. Adding hosts as consumers of the storage on a storage system.
4. Allowing specific hosts access to specific virtual disks on a storage system. This is called
presentation.
See the online help for detailed procedures on each of these steps.
Disk groups
A disk group is a named pool of disk space on a storage system in which individual virtual disks
can be created.
Working with disk groups
The disk group folder for an HP P6000 EVA storage system includes the default disk group, other
disk groups that have been created, plus a folder of ungrouped physical disks that are not members
of any disk group.
(only a portion of the display is shown)
In the various disk group pages you can view component information, operational status, and
perform actions. For example, from the General tab, you can view general information, including
attributes, condition, and capacity. You can also perform actions such as adding physical disks
to the disk group and locating disks.
(only a portion of the display is shown)
26 Provisioning storage
Disk types
The disk type specifies the type of physical disk drives that can be included in a disk group. The
types are:
Online disk type. All physical drives must be Fibre Channel or enterprise SAS drives. This disk type
provides first tier performance and reliability.
Near-online disk type. All physical drives are lower cost, lower performance hybrid Fibre Channel
or midline SAS disk drives. Hybrid drives are dual ported, Fibre Attached Technology Adapted
(FATA) drives. This disk type provides second tier performance and reliability.
Solid state drive disk type. All physical drives must be solid state drives (SSD). This disk type
provides first tier, very high performance and reliability.
Disk type support varies with HP XCS controller software versions. The following table summarizes
support and typical uses.

P6300/P6350/P6500/P6550 EVA
General guidelines
One disk group (the default) is created when the system is initialized. You can add disk groups as
needed.
• Each physical disk drive can belong to only one disk group.
• A single disk group may contain all the physical disk drives in the storage system.
• Multiple virtual disks can be created in a disk group, up to the disk group's capacity.
• Each virtual disk exists entirely within one disk group.
Disk groups 27
Number of physical disks in a group
• With online and near-online disk types, the minimum number of physical disks is 8.
• With the solid state drive disk type, the minimum number of physical disks is 6.
• If the number of disks is not specified when creating a disk group, the minimum is assigned.
If the minimum number of disks is not available, the disk group cannot be created.
• There is no maximum number of physical disks.
Disk group occupancy and occupancy alarm level
The term occupancy refers to the amount of disk space being used for user data in a disk group.
There are two occupancy alarm levels:
• The warning level is the point (percent of capacity) at which the storage system issues a disk
group allocation warning message. The default warning alarm level is 70% of capacity.
• The critical alarm level is the point (percent of capacity) at which the storage system issues a
disk group allocation critical message. The default critical alarm level is 90% of capacity.
For example, if a disk group's capacity is 200 GB, and the default alarm levels are set, a warning
is issued when the total capacity of the virtual disks in the disk group reaches 140 GB, and a
critical message is issued when the total capacity of the virtual disks in the disk group reaches 180
GB.
If you change the occupancy alarm default values, the critical alarm level must be greater than the
warning alarm level.
NOTE: HP P6000 Command View 9.x and earlier have a warning alarm level only. The default
value is 90%.
Disk group capacity
Disk group capacity (in GB) is presented differently for different versions of HP XCS controller
software.
XCS 6.xxx, and XCS 09xxxxxx
The maximum virtual disk size shown cannot exceed 2 TB, regardless of the total capacity.
• Total. Shows the formatted physical disk drive capacity of the disk group.
• Maximum Vdisk Size, Vraid0. Shows the largest virtual disk that could be created in the disk
group, using Vraid0.
• Maximum Vdisk Size, Vraid1. Shows the largest virtual disk that could be created in the disk
group, using Vraid1.
• Maximum Vdisk Size, Vraid5. Shows the largest virtual disk that could be created in the disk
group, using Vraid5.
HP XCS 095xxxxx or later
The estimated capacity is based on factors, such as the estimated number and size of virtual disks
that you might typically create. The actual total capacity can be more or less than the estimates.
The maximum virtual disk size cannot exceed 32 TB, regardless of the total capacity.
• Total. Shows the formatted physical disk drive capacity of the disk group.
• Available, Vraid0. Shows the estimated capacity, if the entire disk group was used for Vraid0
virtual disks.
• Available, Vraid1. Shows the estimated capacity, if the entire disk group was used for Vraid1
virtual disks.

XCS 10000000 or later
• Total capacity. Shows the formatted physical disk drive capacity of the disk group.
• Allocated capacity. Shows the amount of disk group capacity that is being used for virtual
disks.
• Available capacity (estimated). Shows the capacity remaining in a disk group if all new virtual
disks were to be created as either Vraid0, Vraid1, Vraid5, or Vraid6.
◦ Physical. This value is estimated from various factors such as the number and size of
virtual disks that might typically be created. The actual available physical capacity can
be more or less than the estimate.
◦ Thin provisioning. This value is based on the maximum addressable storage space of the
storage system.
• Requested capacity. Shows the amount of space in disk group that has been requested for
virtual disks.
• Oversubscribed capacity. Shows the amount of space requested via thin provisioning that
exceeds the physical capacity that can be allocated.
Redundancy (Vraid) levels
The redundancy (Vraid) level for a virtual disk determines the virtual disk's availability (data
protection) and influences its I/O performance. If you are using XCS 09500000 or earlier, the
Vraid type cannot be changed after a virtual disk is created. For information about changing the
Vraid level on storage systems running XCS 10000000 or later, see “Online virtual disk migration”
(page 33).
NOTE: HP strongly recommends that you use Vraid6 if you are using disk drives with a physical
capacity of 1 TB or greater.
Vraid levels are:
• Vraid0. Is optimized for speed and disk space utilization, but provides no redundancy.
IMPORTANT: HP does not recommend using Vraid0 when high availability is required.
• Vraid1. Is optimized for speed and high redundancy, but requires twice the disk space of
other Vraid levels. Vraid1 provides sufficient data redundancy to recover from a single disk
drive failure. However, if your system uses large capacity disk drives (1TB or larger),
reconstruction time may increase the risk of a second disk drive failure occurring prior to the
completion of reconstruct.
• Vraid5. Is optimized for speed, disk space utilization, and moderate redundancy. Vraid5
provides sufficient data redundancy to recover from a single disk drive failure. However, if
Redundancy (Vraid) levels 29
your system uses large capacity disk drives (1 TB or larger), reconstruction time may increase
the risk of a second disk drive failure occurring prior to the completion of reconstruct.
• Vraid6. Is optimized for speed and the highest redundancy. Vraid6 provides sufficient data
redundancy to recover completely from two disk drive failures.
Vraid6 is applicable only for:
◦ EVA4400, EVA6400, and EVA8400 running controller software 09500000 or later
◦ P6300 EVA and P6500 EVA running controller software XCS 10000000 or later

HP P6000 EVA storage systems use a form of virtualization called virtual disks (vdisks) to store
data. Host computers see virtual disks as real storage objects, exactly as they would see physical
disks with the same characteristics.
Newly installed HP EVA storage systems are not pre-configured with virtual disks. After you initialize
the storage system and create disk groups, you can create virtual disks in the sizes and Vraid types
that you need. The storage system automatically determines where data is actually stored on the
physical disks. You do not need to have knowledge of individual physical disks in the storage
system.
In HP P6000 Command View 9.3 or later, when a LUN is provisioned with Vraid0 redundancy,
the HP P6000 Command View GUI displays an R0 icon on the LUN. If you select Vraid0 when
creating a LUN HP P6000 Command View displays a confirmation window to verify that redundancy
is not required.
Working with virtual disks in HP P6000 Command View
The virtual disks folder for an HP P6000 EVA storage system displays all virtual disks, regardless
of type. You can further organize virtual disks into subfolders that you create and name. You can
also move virtual disks from one subfolder to another.
(only a portion of the display is shown)
In the various virtual disk pages you can view virtual disk information, operational status, and
perform actions. For example, you can view general information, operational status, presentation,
and data replication (DR group) membership. You can also perform actions such as replicating
the virtual disk (creating snapclones, snapshots and mirrorclones) or migrating the disk group or
Vraid of a virtual disk.
NOTE: The GUI only displays action buttons that are supported in your configuration.
