Configuring HP StorageWorks P9000 Command View Advanced Edition Suite
In the graphic below, configuring a browser means setting up the browser environment to correctly
display and run HP StorageWorks P9000 Command View Advanced Edition Suite. If you have issues,
check your browser setup.
After you set up the browser environment, you can log in.
If storage administration is to be shared, investigate the topic on managing users.
Setting up storage resources
Collectively, storage systems and hosts are called storage resources. For storage resources to be
managed by Command View AE Suite, they must be registered.
Registration of storage resources requires the resource to be reachable on the network by IP address.
After you register storage and host resources, you can begin allocating volumes to hosts.
Before setting each resource, check the system prerequisites, and check settings requirements for the
corresponding system configuration described in the HP P9000 Command View Advanced Edition
Suite Software Administrator Guide.
Configure the prerequisite environment based on requirements. For example, set software licenses by
using Remote Web Console or other storage management tools, or configure a network based on
the system configuration.
If Device Manager is set up in an environment that has already been configured using Remote Web
Console, and if you want to use volume labels THP/Smart pool names from a storage system in Device
Manager, register the storage system in Device Manager, and then apply the storage system labels
to Device Manager.
This diagram describes the basic task flow for setting up storage resources.
Setting up users and access control
After users are registered, you can limit the scope of allowed operations for each user by configuring
access control settings for users and storage resources.
User Guide 21
To set access control you will need to create resource groups and user groups, then assign the resource
groups and roles to the user groups.
Creating a storage operating environment
To be able to use volumes of a storage system from hosts configure the operating environment
beforehand. The workflow for configuring the environment differs depending on the scale and operation
method of the storage systems.
In some environments, you can virtualize storage devices so that multiple, different storage systems
can be used as a single storage system.
If your storage system supports THP/Smart pools, you can create THP/Smart pools such that virtual
volumes can be allocated to hosts. By virtualizing storage devices and storage capacity, you can
decrease both management and operational costs by more effectively using physical resources.
Allocating storage
Volumes are allocated to hosts for applications needing storage. A variety of methods for allocating
volumes is available. For example, you can select one or more hosts, then identify and allocate existing
volumes. You can also select one or more volumes, then identify the host that needs the volumes. You
can also establish I/O paths between hosts and volumes when you allocate volumes.
To prepare for loss of data caused by disk failure, disasters, or other issues, you can manage the
redundancy of important operational data by creating a replication environment for volumes within
a storage system or between storage systems, as necessary.
By using logical groups, volumes can be managed as a group for purposes of organization and
simplification of user tasks.
Overview of HP StorageWorks P9000 Command View Advanced Edition Suite22
Monitoring storage
You can check the status of storage resources to detect problems and output reports to a CSV or PDF
file containing search results or configuration and capacity information about storage systems, hosts,
volumes, logical groups, and other storage resources.
If you have the Tiered Storage Manager license, you can see the operational status of storage resources
from the Mobility tab and perform integrated operations to optimize data placement.
This information can be used to migrate volumes or add THP/Smart pool volumes to optimize storage
resources. The following graphics illustrate the flow of monitoring and checking the status of storage
resources. To check daily operational status, inquiries from a host or application administrator, or for
Service Level Objective (SLO) and Service Level Agreement (SLA) inquiries, see the respective figures
below:
In summary, you can:
• View summary information from the Dashboard tab.
• Check alerts from the Tasks & Alerts tab or the dashboard.
• Search storage resources from the Search box on the tabs bar.

2 Discovering, registering, and adding management targets
This module describes how to discover SAN resources, such as storage systems, and hosts.
Registering storage systems
This module describes how to register storage systems.
About registering and removing a storage system
Registering (discovering) a storage system in Command View AE Suite enables you to manage the
storage system's resources, including:
• Parity Groups
• LDEVs
• Volumes
• THP/Smart pools
• Resources available through external storage connections
When you specify IP address (or host name) and authentication information for a storage system, the
storage system is discovered based on the specified information. For SMI-S enabled storage systems,
the SMI-S provider's IP address is used for discovery.
Note that information about a storage system can be changed after the storage system is registered.
If managing a storage system with Command View AE Suite is no longer necessary, for example
because of reorganization, you can remove the registered storage system. Removal will result in the
following:
• Configuration information such as parity groups, volumes, and allocated paths will be retained
in the storage systems themselves.
• When storage systems are excluded from management by Command View AE Suite, the information
set in Command View AE Suite, such as tiers and data placement profiles, is deleted.
Prerequisites for registering a storage system
Before you can discover and register a storage system, you must collect and confirm the following
storage system information:
• Storage system type.
• Storage system IP address (IPv4 or IPv6) or host name (alias name).
• User name and password for the storage system management tool, such as Remote Web Console.
• Host name (alias name) or IP address for the SMI-S provider (IPv4 or IPv6), user name, password,
port number (for SMI-S Enabled storage systems).
User Guide 25
• Protocol used for Device Manager and SMI-S provider communication (for SMI-S Enabled storage
systems).
Tasks to be completed beforehand:
• Connect the target storage system to the network.
• Verify that fibre Channel port settings (such as topology and transfer rate) are specified in the
management tool of the storage system, such as Remote Web Console.
• Register accounts to be used for Device Manager in the management tool of the storage system,
such as Remote Web Console.
NOTE:
If the storage system is P9500 Disk Array set the "Administrator" user group (built-in group) for
the accounts to be registered.
• Verify that the SMI-S provider is set (for SMI-S Enabled storage systems) before registration.
Registering a storage system
A storage system must be registered to manage it from HP StorageWorks P9000 Command View
Advanced Edition Suite. When registered, the storage system becomes a managed resource.
1. On the Administration tab, select Managed Resources.
2. On the Storage Systems tab, click Add Storage System.
3. Specify registration information. This means:
• An IP address (or hostname) and authentication information (username, password) for most
supported storage systems.
• For SMI-S enabled storage systems, you will need to specify the SMI-S provider IP address,
authentication, protocol (secure, not secure) and possibly a non-default port number.
TIP:
If an SMI-S provider that manages multiple SMI-S enabled storage systems is specified, all the
SMI-S enabled storage systems under that provider are registered.
4. Click OK.
5. Check the Data Collection Tasks tab to verify that the task has completed successfully.
6. When the task completes, confirm that the storage system appears on the Storage Systems tab
of Managed Resources, or in the Storage Systems tree on the Resources tab.
The storage system is now a managed resource. This typically means volumes can be allocated to
registered hosts.
TIP:
To remove storage systems, select one or more storage systems, and click Remove Storage Systems.
Discovering, registering, and adding management targets26
Changing storage system information
You can modify the IP address or host name or login user name and password for a storage system.
You can select multiple storage systems to modify at one time, but when selecting multiple storage
systems, only the login user name and password can be modified.
1. On the Administration tab, select Managed Resources.
2. On the Storage Systems tab, select the storage system, or storage systems, you want to modify.
3. Click Edit Storage Systems.
4. Specify the appropriate items and click OK.
5. Check the Data Collection Tasks tab to verify that the task has completed successfully.
6. Confirm that the information in the storage system list is updated.
About acquiring the most recent storage system information
To get current information about a target storage system, you can manually refresh the system at any
time.
When you refresh a storage system, displayed information is updated for storage resources, such as:
• Volumes
• Parity groups
• THP/Smart Pools
• External storage connections
TIP:
When data placement profiles for Smart volumes are being managed, you can specify an option in
the Refresh Storage Systems dialog box to search for inconsistencies in data placement profiles.
To update information about hosts, such as the host name, WWNs, refresh the hosts.
To update host bus adapter (HBA) WWN nicknames, refresh one or more storage systems. Refreshing
host information does not update WWN nicknames. When several WWN nicknames are assigned
to a single HBA, only one of the nicknames is displayed for that HBA.
If connected to P9000 Performance Advisor Software, users can also update performance information
that is displayed in the Mobility tab. To automatically update the storage system information, specify
proper settings in the server.properties file or dispatcher.properties file of the
management server. For details about specifiable values, see the HP P9000 Command View Advanced
Edition Suite Software Administrator Guide.
Acquiring the most recent storage system information
You refresh storage systems to update the displayed information.
1. From the Administration tab, select Managed Resources.
2. On the Storage Systems tab, select one or more storage systems to refresh.
3. Click Refresh Storage Systems, then OK.
4. Check the Data Collection Tasks tab to verify the completed task.
Check for updated storage system information from the Storage Systems tab. Updated storage system
information is also displayed from the Resources tab, Storage Systems tree.
User Guide 27
TIP:
Label information for volumes and THP/Smart pools is not refreshed. To apply label information being
managed on a storage system to Device Manager, click Refresh Labels.
Operations available to SMI-S Enabled storage systems
You can register storage systems that are managed by an SMI-S provider (SMI-S Enabled storage
systems) as HP StorageWorks P9000 Command View Advanced Edition Suite resources.
The user can perform the following operations to SMI-S Enabled storage systems:
• Register, change, delete, and update SMI-S Enabled storage systems.
• View summary information for SMI-S Enabled storage systems.
• Operate SMI-S Enabled storage systems from the SMI-S Enabled storage system management tool
(activate the management tool from Element Manager).
• Connect or disconnect as external storage systems (by executing CLIs).
Users must be assigned All Resources to reference or perform operations on SMI-S Enabled storage
systems.
For the operations that are executed by CLI, see the HP P9000 Command View Advanced Edition
Suite Software CLI Reference Guide.
Registering hosts
This module describes how to register hosts.
About registering and removing a host
You can register hosts as managed resources using Device Manager so that storage system volumes
can be used by the hosts and their applications.
The following hosts can be registered for Command View AE Suite:
• Normal hosts (An open host that is not virtualized)
• Virtualization servers (A physical server where virtualization software is installed)
• Virtual machines (A machine that is created on the virtualization server and operates on virtualiz-
ation software)
Depending on the user's purpose, multiple methods are provided for registering one or more hosts,
including manual registration, Host Data Collector (agent-less discovery) or Device Manager agent.
For host prerequisites and environment settings, see the HP P9000 Command View Advanced Edition
Suite Software Administrator Guide.
You can also monitor the usage status of storage resources from the host point of view, such as
generating reports for charging each host that meets its actual capacity.
If hosts no longer have to be managed, for example because of reorganization, remove the registered
hosts. Configuration information, such as LUN paths set during volume allocation, are retained on
the storage systems, but because the host is excluded from management by Command View AE Suite,
information about deleted hosts is deleted from the logical groups that are set in Command View AE
Suite.
Discovering, registering, and adding management targets28
Methods for registering hosts
Methods for registering one or more hosts, using host installed agents or agent-less discovery include:
Table 1 Methods for registering hosts
DescriptionMethodPurpose
To manually register individual
hosts.
To register multiple
hosts in a batch.
To know the usage
status of storage
resources for the
virtualization servers, or the correspondence with the
virtual machines.
Register each
host by
WWN.
Use Host
Data Collector.
Use Host
Data
Collector
or
Use vMA
(vSphere
Management
Assistant).
When you want to register hosts in Command View AE Suite based on
WWN, manually specify the host name, OS type, and WWN information.
Hosts can be registered without Host Data Collector or Device Manager
agent setup.
When you want to register multiple hosts in a batch, register multiple
hosts by specifying the IP address (range specification and listing
addresses are available), and the authentication information of the host
on the network. The host’s WWN information will automatically be
obtained.
If you want to allocate volumes to an FCoE port, you need to manually
add a WWN.
Host Data Collector setup is required.
When you want to know the usage status of storage resources for the
virtualization servers, or the correspondence with the virtual machines
and you want to register both the virtualization server and the virtual
machine, the virtualization server must use NPIV (N-Port ID Virtualization)
HBAs, and be connected with Fibre Channel. For some virtualization
server software versions, the virtualization server can be discovered by
either specifying the vMA IP address and account, or by using Host Data
Collector.
For VMware ESX 4.x and VMware ESXi 4.x, a discovery can be
performed either by specifying the vMA information, or by using Host
Data Collector.
For VMware ESXi 5.x, a discovery can be performed only by using Host
Data Collector.
For virtual machines, install Device Manager agent or use Host Data
Collector to specify the IP address (range specification and listing
addresses are available), and the authentication information of the host
on the network.
Note that if the virtualization server is not using NPIV HBAs, either a
virtualization server or a virtual machine can be registered per HBA unit
(both a virtualization server and a virtual machine cannot be registered
in the same WWN).
To automatically
acquire host information, or to
manage a copy
pair by using the
replication functionality of the volume.
Use Device
Manager
agent.
When you want to automatically acquire host information, or to manage
a copy pair by using the replication functionality of the volume, install
Device Manager agent on each host or on the management server of the
copy pair. Host information or copy pair information will be sent from
Device Manager agent. For details about how to install the Device
Manager agent, see the HP P9000 Command View Advanced Edition
Suite Software Installation and Configuration Guide.
To exclude a host from management by Command View AE Suite, uninstall
the Device Manager agent, and then remove the host using Command
View AE Suite.
If you want to allocate volumes to an FCoE port, you need to manually
add a WWN.

.
When registering hosts, if the hosts you want to register include a host that has a WWN that has
already been registered, or includes multiple hosts that have the same WWN, the host which acquires
the WWN is determined based on the product or application that detects it.
When hosts are registered by multiple methods, the WWN acquisition priority, listed from highest to
lowest, is as follows:
1. A virtualization server.
2. A host registered by using Device Manager agent.
3. A normal host or a virtual machine registered by using Host Data Collector.
4. A manually registered host.
When hosts with the same WWN are registered by the same method:
• The WWN is registered to the host that was registered last.
• When a normal host or a virtual machine is registered by a virtualization server or Host Data
Collector, WWN is registered to the host that was registered first.
Registering hosts by using Host Data Collector
Use Host Data Collector to register multiple hosts, virtualization servers, and virtual machines in a
single operation.
Items to check beforehand:
• Host OS type
• Host IP address (IPv4)

Workflow for detecting hosts
This topic describes how hosts are detected and registered in Device Manager. Read this topic if you
are installing HP StorageWorks P9000 Command View Advanced Edition Suite software in an
environment that was configured by using Remote Web Console.
A host group is configured on the storage system side, and the storage system is registered in Device
Manager. After that, if a host is detected by Device Manager, a host group in the storage system that
is selected at the time of detection of the host is registered in Device Manager. If the same WWN is
registered to multiple hosts, only the WWN with the same name as the host that is already registered
in Device Manager is added to the host. The following shows an example of host detection:
User Guide 33
In this diagram, the WWN of 22.22.22.22.22.22.22.22 for host group AAA is added to host AAA,
which has the same name as the host group. The WWN of host group BBB is already registered to
host AAA, and host BBB cannot be registered in Device Manager. Host CCC, which has the same
name as host group CCC, is added to Device Manager, and the WWN of 33.33.33.33.33.33.33.33
for host group CCC is registered to host CCC.
If one host that has multiple WWNs is detected, even if it is one host in the actual environment, it
might occasionally be registered as multiple hosts by Device Manager. This is because hosts are
generated in host groups when one host has multiple WWNs. In this case, the hosts must be merged.
Merge the WWNs . Merge the hosts that have been added as multiple hosts in Device Manager into
one host. WWN information is merged, and the source hosts are deleted automatically.

Registering hosts using host scan
You can register hosts by scanning hosts to manage and monitor the hosts.
Information to check beforehand:
• Host names
• The name of a host group is the same as the actual host, and the WWN for that host is set for
LUN security.
• Only a single host can be related to each host group.
Tasks to be completed beforehand:
• LUN Manager or LUN Management must be installed on the target storage system.
1. From the Administration tab, select Managed Resources.
2. From the Hosts tab, click Host Scan.
3. Specify the necessary items, and then execute the host scan.
Registered hosts can be viewed in the resource tree view.

Discovering, registering, and adding management targets34
Registering hosts using merge hosts
You can use merge hosts to combine source and target host information into a single surviving target
host that is registered.
Tasks to complete beforehand:
• Identify the names of the source and target host. Note that the source host is merged into the target
host, then the source host is deleted.
• Ensure the source host has been registered either manually or by host scan
• Ensure the target host is not a mainframe host, or a virtual host
• Ensure the target host has at least one registered WWN.
1. From the Administration tab, select Managed Resources.
2. Select the Hosts tab, select the target host row, click More Actions and select Merge Hosts.
3. In the merge hosts window, select the source host, then click Confirm.
4. Review the target (surviving host) and source (host to be deleted) information.
• If the target and source host information is correct, click Ok.
• If the target or source host information must be changed, click Back.
• To abandon the task, click Cancel.
On the Resources tab, in the hosts tree, confirm the target host information and the source host removal.
You can also confirm this on the Administration tab > Managed Resources > Hosts tab.
About changing host settings and information
You can change host settings and update previously registered host information.
Depending on how a host was registered, there are two ways to change host settings and information:
• Refresh Hosts
• Edit Hosts
Choose the appropriate method to change host settings and information, depending on how the hosts
were registered and the operational status. For example, Refresh Hosts updates a host by obtaining
information from Host Data Collector or Device Manager agent. Edit Hosts allows the user to manually
change host settings.
The host editing method allows the user to manually change host settings.
TIP:
The settings for the host's WWN are not linked to the settings for the host group on the storage system
side. Use the ModifyPort command to change settings for host groups, or host mode options. For

3 Managing storage resources in a SAN environment
This module describes managing storage resources such as THP/Smart pools and volumes in a Storage
Area Network (SAN).
Creating and deleting volumes
This module describes how to create volumes (including LUSE volumes), and delete unallocated
volumes.
About creating volumes
You create volumes, then allocate them to a host.
You create volumes by using the available space in a THP/Smart pool or parity group. You can then
access the volumes when you are ready to allocate them to a host. If, while allocating volumes to a
host, no volumes match the specified requirements, volumes are automatically created using the
available space. Note that when a basic volume is created, the volume is also formatted at the same
time.
Newly created volumes are included in the list of Open-Unallocated volumes until you allocate them
to a host.
Because creating volumes takes time, you should create volumes in advance.
Creating volumes
For registered storage systems, volumes are created so they can be allocated to hosts.
Tasks to complete beforehand:
• Identify the storage system
• Identify the number of volumes to create
• Identify volume types and capacities
1. On the Resources tab you can create volumes from several locations:
• From General Tasks, select Create Volumes.
• Select the storage system, click Actions, and select Create Volumes.
• Select the storage system, list existing parity groups, and click Create Volumes.
• Select the storage system, list existing THP/Smart pools, and click the Create Volumes button
or select Create Volumes from Actions.
2. In the create volumes dialog box, configure volumes and their characteristics.
3. Click Show Plan:
a. Review all plan information. If changes are needed click Back.
User Guide 41
b. Enter a task name and description.
c. Schedule the task for now, or a later date and time.
d. If scheduled for now, select View task status to monitor the task when submitted.
e. Click Submit to queue the task.
4. On the Tasks & Alerts tab, confirm task completion. If status is not completed, click the task name
to review the message.
Created volumes are added to the target storage system Open-Unallocated volume list.
Create volumes dialog box
Created volumes are placed in the Open-Unallocated folder of the user selected storage system so
they can be allocated to hosts as required.
TIP:
It is not required that you configure every dialog box field. When the minimum required information
is entered, the Show Plan button will activate allowing review of the recommended plan. If desired,
use Back to customize the plan with specifications that meet your requirements.
Below, field groups are indicated by >>. Field groups expose information or fields when clicked, and
hide information or fields when clicked again.
When using a dialog box, errors are displayed at the top of the dialog box with a problem description.

About creating a LUSE volume
A LUSE volume is collection of two or more basic volumes that have been grouped together to increase
available capacity.
If the capacity of the LUSE volumes or basic volumes that have already been allocated to hosts becomes
insufficient, you can increase capacity by adding unallocated volumes or creating LUSE volumes.
LUSE volumes are created by using volumes that belong to the same resource group, have the same
drive type, and are at the same RAID level.
Creating a LUSE volume
Information needed before creating a LUSE volume:
• The name of the target host
• The target volumes (LUSE volumes or basic volumes that are already allocated to the host).
Tasks to complete before creating a LUSE volume:
• Creating volumes to be added
1. From the Resources tab, select Hosts.
2. Expand the tree and select the target OS.
3. Select the target host from the list of hosts, and from the displayed list of volumes select the LUSE
volume or basic volume, and then click the Create LUSE Volume button.
4. Click the Add Volumes button.
5. Select a volume(s) to be added, and then create a plan.
6. If there is no problem, execute the plan.
7. View the list of tasks to make sure that all tasks are complete.
From the list of volumes of the target host displayed by expanding the tree of the Resources tab,
information about the created LUSE volume can be checked.
About releasing a LUSE volume
To release a LUSE setting, the LUSE volume must first be unallocated from all hosts. Users can release
a LUSE setting either by selecting it or using the Unallocating Volumes dialog box.
Releasing a LUSE volume
To release a LUSE volume, you release the LUSE setting for the target volume.
Before releasing a LUSE volume, make sure that it has been unallocated from all hosts.
1. On the Resources tab, expand the Storage Systems tree, and for the target storage system, select
Volumes and Open-Unallocated.
2. From the list of volumes, select the volume for which the LUSE setting is to be released, and click
the Release LUSE Volumes button.
3. If there is no problem, execute the plan.

Virtualizing external storage
This module describes virtualizing external storage so external volumes can be managed.
About virtualizing volumes
Virtualizing volumes is the process of mapping external storage system volumes to an internal storage
system.
This allows centralized management of volumes from multiple external storage systems, in addition
to the volumes from the single storage system being managed with HP StorageWorks P9000 Command
View Advanced Edition Suite.
The volumes in the external storage system (registered and referred to as external volumes) can
be managed in the same way as the volumes in the internal storage system (registered and referred
to as internal volumes).
When external storage is managed by an internal storage system, external volumes will be listed in
the External Storage folder of the internal storage system.
External volumes can be used for various purposes, including:
• External volumes can be allocated to hosts the same as internal volumes are.
• Important data on internal volumes can be backed up to external volumes.
• Infrequently accessed data on internal volumes can be moved to external volumes for archiving.
To externally connect an SMI-S Enabled storage system, CLI commands are required. For details about
how to use CLI commands to externally connect a storage system, or disconnect an external connection,
see the HP P9000 Command View Advanced Edition Suite Software CLI Reference Guide.
Virtualizing volumes
Volume virtualization provides the capability to optimize storage services to applications by facilitating
movement of data between tiers and migration of data between different generations of technology.
Tasks to complete beforehand:
• The internal and external storage systems are registered in HP StorageWorks P9000 Command
View Advanced Edition Suite.
• The external storage system is connected to one or more external ports of the internal storage
system.
• External Storage Software is installed on the target storage system.
• Identify the number and capacity of volumes you are virtualizing.
• Identify the number of external paths between the external and internal storage systems.
1. From the Actions menu, or General Tasks, select Virtualize Volumes.
2. Specify the appropriate information.
To change default values, select one or more of the following:
• External Path Priority Settings
• Host Group and LUN Settings
• External Volume Configuration
3. Click Show Plan:
User Guide 45
a. Review all plan information. If changes are needed click Back.
b. Enter a task name and description.
c. Schedule the task for now, or a later date and time.
d. If scheduled for now, select View task status to monitor the task when submitted.
e. Click Submit to queue the task.
4. When the task completes, check the internal storage systems External Storage folder to confirm
the external volumes are mapped to the internal storage system.
Virtualizing storage capacity (THP/Smart)
This module describes how to virtualize storage capacity.
About virtualizing storage capacity
HP StorageWorks P9000 Thin Provisioning (THP) provides virtual volumes to a host and allocates the
actual capacity from a THP pool when a host makes a write request. By using THP pools, you can
allocate more capacity to a host than that allowed by the actual physical configuration of the storage
system.
THP pools provide the following advantages:
• You can reduce system setup and operational costs.
• You can use resources more efficiently.
• You can distribute workload equally among volumes.
Smart Tiers (Smart) improves THP pools storage performance further by taking advantage of
performance differences between hardware tiers.
You can create virtual volumes (THP/Smart volumes) from physical volumes that are grouped into
THP/Smart pools. You can then allocate those virtual volumes to hosts.
In the illustration below, note that the volumes used to create the THP/Smart pool are called THP/
Smart pool volumes. The THP/Smart pool is then used to provide capacity as needed to allocated
THP/Smart volumes.
THP/Smart pools are created by Device Manager, which automatically selects volumes based on
user-specified conditions. Users can also directly specify parity groups to create a THP/Smart pool.
Managing storage resources in a SAN environment46
Users can also specify settings such as values for the usage rate threshold and reservation threshold.
If a Tiered Storage Manager license has been registered, user can use the Mobility tab to evaluate
and analyze the operation status that is related to a THP/Smart pool. When you delete an unnecessary
THP/Smart pool, THP/Smart volumes created from that pool are also deleted. For this reason, a
prerequisite to deleting a THP/Smart pool is that no THP/Smart volumes from that pool are allocated
to a host.
Creating a THP/Smart pool
You can create a THP/Smart pool using physical volumes. This provides more efficient use of physical
storage for virtual volumes allocated to hosts from the THP/Smart pool.
Tasks to be completed beforehand:
• Register the target storage system.
• When defining an external LDEV tier rank, a storage system that has multiple performance levels
must be externally connected.
Verify the following when using XP24000/20000 and HP StorageWorks P9500 Disk Array for THP
pools:
• Only parity groups from which volumes have already been created can be targets
Verfiy the following when using HP StorageWorks P9500 Disk Array for Smart pools:
• Hardware tier: drive type and drive speed (RPM)
• Only parity groups for each hardware tier from which volumes have already been created can
be targets
1. On the Resources tab you can create pools from several locations:
• From General Tasks, select Create Pool.
• Select the storage system, list existing THP Pools, and click Create Pool.
• Select the storage system, list existing THP Pools, and click Actions, then select Create Pool.
2. In the create pool dialog box, configure THP or Smart pools and their characteristics.

-
Note the following important items regarding Smart configuration:
• The web client will automatically arrange your tiers from
highest performance (Tier 1) to lowest performance (Tier 3),
regardless of the order used while defining your tiers. For example, if SAS 15000 is your final tier definition, but is the
highest performance tier, SAS 15000 will be displayed as
Tier 1, not Tier 3. Essentially, the web client re-arranges and
re-orders your tier definitions so that they are correctly ordered
in terms of performance levels. This provides easy and flexible
tier creation for the administrator.
• When all 3 tiers are defined, the + tab is no longer displayed
since 3 tiers is the limit. If you delete a tier tab using the close
box (X), the + tab is again displayed, allowing for a new tier
definition. With only 1 or 2 tiers defined, the + tab is visible,

Buffer Space for Tier relocation
The administrator manually starts and stops performance monitoring and tier relocation.
The administrator creates performance monitoring and tier relocation plans in the form of named templates with different performance monitoring and tier relocation settings. Multiple templates
can be created, edited, and assigned to different tiers.
Continuous monitoring mode uses weighted-average performance
data over several monitoring cycles (see Cycle time above) so that
tier relocation does not respond immediately to workload changes.
Basically, this is used to prevent an over-reaction to workload
changes, resulting in unnecessary tier relocation I/O.
Periodic monitoring mode uses the performance data from the last
monitoring cycle (see Cycle time above). Tier relocation responds
immediately to workload changes. Basically, this is a more aggressive tier relocation monitoring mode.
Sets the buffer space used for new page assignments to Smart
tiers. The default values are recommended.
Sets the buffer space used for tier page relocations between Smart
tiers. The default values are recommended.

Virtualizing storage tiers (Smart)
This module describes how to manage data relocation for Smart volumes.
Managing storage resources in a SAN environment52
About virtualizing storage tiers
Smart Tiers functionality monitors the frequency at which data is accessed and relocates that data
based on the results. The user creates a pool that combines volumes of different cost performances,
such as combining high-speed volumes (SSD or SAS) with inexpensive low-speed volumes (SATA).
The data in this pool is then automatically relocated among the volumes. This relocation is performed
depending on the I/O load:
• high-load pages are allocated to high-speed volumes
• low-load pages are allocated to low-speed volumes
By using HP StorageWorks P9000 Command View Advanced Edition Suite software, you can fine-tune
settings related to the monitoring of Smart pools and data relocation depending on operating
conditions. By specifying settings that correspond to business conditions or the characteristics of certain
applications, you can optimize data placement, improve volume performance, and reduce costs
through the effective use of resources.
Smart settings that can be specified by using Command View AE Suite include:
• Monitoring Smart pools and relocating data - Smart pool monitoring and data relocation can be
performed. Monitoring and data relocation can be set to execute automatically by specifying a
time or interval in advance, or you can manually execute at a time of your choice according to
the requirements of your work.
• Specifying the buffer space for Smart pools - When Smart pools are created or edited, on each
hardware tier, you can specify a ratio corresponding to the buffer space for new page assignment,
an area reserved for increasing used capacity. Similarly, you can specify a ratio corresponding
to the buffer space for tier relocation, a working area reserved for the storage system to use when
relocating data. Changing the default values, however, might degrade performance, so we recommend using the defaults.
• Applying a tiering policy to Smart volumes - In a Smart pool, data that has a high frequency of
I/O operations is preferentially placed in a high-speed hardware tier automatically. To ensure
that data with high importance but with few I/O operations is placed in a hardware tier that
maintains a certain speed at all times, you can fix the target hardware tier. You can also apply
a tiering policy to Smart volumes that determines the capacity ratio of each hardware tier, by
defining such a policy in advance. You can regulate tiering to allow for operation that balances
performance and cost, such as by preventing more data than is necessary from being placed in
a fast hardware tier and thereby reducing management costs. After a tiering policy has been applied, regularly review the status of the settings of that tiering policy and the amount of capacity
in use by each hardware tier to verify that resources are being appropriately allocated. Tiering
policy definitions can be changed if costs are greater or performance is lower than expected.
• Editing a tier rank for an external Smart pool volume - When an external volume is included in a
Smart pool volume that is one of the volumes making up a Smart pool, you can define the external
LDEV tier rank (high, medium, or low) according to the performance.
A registered Tiered Storage Manager license enables the following:
• Evaluating and analyzing the operation status of Smart pools - Use the Mobility tab to evaluate
and analyze the operation status that is related to a Smart pool.
• Setting a schedule for relocating data and monitoring Smart pools - Register the time of Smart
pool monitoring and data replacement as a template schedule.
• Editing tier relocation for Smart volumes (preventing relocation by volume) - Users can set whether
data can be relocated for each Smart volume. Tier relocation can be controlled according to
characteristics and the operating status of the applications using Smart volumes, such as by preventing other applications from relocating data of the volumes they are using when there is an
application for which data relocation takes a high priority.
User Guide 53
• Restoring a data placement by applying a data placement profile of Smart volumes - Users can
restore a past data placement by saving data placements of optimized Smart volumes per page
as profiles, and applying them according to operation. For example, if a Smart volume is being
used for multiple operations that have different access characteristics (such as online and batch
processing), users can create data placement profiles that fit the different processes, and apply
the appropriate profile before beginning processing. By doing so, users can restore a data
placement that fits the characteristics of the target processing in advance, which prevents I/O
performance from dropping. In addition, by setting up a schedule, users can update and apply
profiles at regular intervals to suit the operation of applications. Profiles are applied only to pages
placed in Tier 1 of Smart pools.
Manually starting or stopping the monitoring of Smart pools

Notes on data placement profiles for Smart volumes
When using data placement profiles for Smart volumes, it is useful to understand the following:
• Data placement profiles are applied only to pages placed in Tier 1 of Smart pools.
• For pages to which both a data placement profile and tiering policy are set, the settings of the
profile are prioritized.
• After a data placement profile has been applied and monitoring and data relocation of Smart
pools has been performed, a data placement is restored. Therefore, users need to determine the
timing at which to apply a profile by taking into account the period during which the monitoring
and data relocation are performed.
• When performing a create, update, apply, or release of a data placement profile, or when
searching for or repairing an inconsistency in a data placement profile, users cannot perform
other operations for the target storage system.
• A task to create, update, apply, or release a data placement profile or to search for or repair an
inconsistency in a data placement profile takes time to complete after it is executed. This time
might affect other operations, so make a plan based on the displayed time estimate. Keep in mind
that the larger the number of target volumes, the more likely that the estimated time and the actual
execution time will differ greatly. You can also stop tasks that are being executed.
• Regardless of the allocated resource groups, data placement profiles created by another user can
also referenced in the list of profiles. However, operation that can be performed on such profiles
are restricted based on the allocated resource group and role.
Managing storage resources in a SAN environment56
• If the number of managed data placement profiles exceeds 200, displaying the profile list might
take some time. In this case, set the [Rows/page] of the profile list to no more than 100.
• When the operations listed below are performed, users need to perform a search inconsistency
operation from the Refresh Storage Systems dialog because the profile that is actually applied to
the volume in a storage system might not match the profile information that can be referenced
from HP StorageWorks P9000 Command View Advanced Edition Suite.
• When the HP StorageWorks P9000 Command View Advanced Edition Suite database was
overwritten, due to an import or restoration, while the applied profile existed.
• When the storage system that contains an applied profile is deleted, and the storage system
is re-registered.
TIP:
If inconsistencies are detected, a message will be displayed in Manage Data Placement Profiles dialog.
From the link shown in the message, perform the repair inconsistencies operation and
release the profile. This can avoid unintended data to be fixed into a high-speed hardware tier by a
profile that was applied in the past.
Creating a data placement profile for Smart volumes
To restore a data replacement appropriate for application processing, the user creates a data placement
profile when Smart volumes provide sufficient performance. A profile can be created for each logical
group, and is managed with the corresponding logical group.

Allocating and unallocating volumes
This module reviews volume allocation requirements, methods, and related procedures for allocating,
or provisioning, volumes.
About allocating volumes
Volume allocation makes storage capacity available to host applications or clustered hosts and
applications. Hosts must be registered before volume allocation.
Depending on your registered storage systems, volumes can be allocated using basic volumes, pool
volumes, or volumes from a tier. Basic volumes are volumes from a parity group. Any storage system
can provide basic volumes. Allocating THP/Smart pool volumes involves grouping resources on
storage systems that support this feature. THP/Smart pools must exist prior to volume allocation from
a THP/Smart pool. To allocate volumes from a tier, a Tiered Storage Manager license is required,
and tier policies must be established for storage systems that support tier policy configuration.
Volume allocation behaviors include:
• The settings assigned when allocating volumes to a host become the default settings for the next
volume allocation to the same host, but can be changed during volume allocation.
• If a variety of volumes with different characteristics have been allocated to a host, you can allocate
a new volume by selecting an existing volume to set the volume allocation criteria.
• If no volumes match the specified requirements, new volumes are created from unused capacity
and allocated to the host. When a basic volume is created, the volume is also formatted at the
same time.
• You can use keyword or criteria based searches to find existing unallocated volumes that meet
your requirements.
• When you allocate volumes to a host, LUN paths are assigned automatically. LUN paths are
storage port to host port mappings providing host access to volumes. The host port is a host bus
adapter (HBA). WWN nicknames can be displayed by the user to confirm target HBAs for a host
while editing LUN paths during, or after, volume allocation.
• Volumes can be allocated on ports where LUN security is not enabled. All hosts with access to the
port can access the volume.
• Volume allocation to a cluster should be done with logical groups. This ensures the same volumes
are allocated to all hosts in the cluster.
• Volume allocation does not occur until you approve the volume allocation plan and submit the
volume allocation task.
• When volumes are allocated to a host OS, you must create a file system on them and mount them,
before they can be used by host applications.
User Guide 61
NOTE:
Before allocating volumes, review the available volume allocation methods. This will optimize your
ability to perform volume allocation, and help you understand the Allocate Volumes dialog box.
Volume allocation methods
When you allocate volumes, you can either:
• Select resources, such as volumes or hosts, then start the Allocate Volumes dialog box.
• Start the Allocate Volumes dialog box without first selecting a resource such as a volume or host.
If you select resources first, the Allocate Volumes dialog box will prompt you for less information.
Note that every volume allocation method involves clicking Allocate Volumes using a button, an Actions
pull-down menu item, or a General Tasks menu item, to start the Allocate Volumes dialog box. The
visible fields in the dialog will vary depending on your allocation method.
Volume allocation methods include:
• General tasks
From the Resources or Mobility tab, from General Tasks, click Allocate Volumes. This starts the
allocate volumes dialog screen. Because no resource was selected, you must configure host,
volume, and other volume allocation requirements.
• Selecting hosts
From the Resources tab, select one or more hosts, and click Allocate Volumes. The dialog will
display the selected host names instead of prompting.
• Selecting volumes
From the Resources tab, select one or more volumes, and click Allocate Volumes. The dialog will
prompt for host name, but will not prompt for volume criteria.
• Selecting clustered hosts
Configuring clustered hosts in a logical group helps ensure that volume allocations will be consistent
for all members of the cluster. From the Resources tab, select a logical group, select all host
members of the group, and then click Allocate Volumes. If clustered hosts are not in a logical
group, from General Tasks or Actions, click Allocate Volumes and select multiple hosts. You may
also use the Resources tab to locate clustered hosts, and then Allocate Volumes. The use of logical
groups is recommended to avoid host selection errors.
• Searching
You can search for volumes meeting specific criteria (such as storage system, specific allocation
status, volume type, drive type, or drive speed, etc.), select one or more volumes from the search
results, and click Allocate Volumes.
You can also search using full or partial text keywords such as storage system name or host name,
and allocate volumes to the selected resource. This eliminates manual navigation to the resource.
• Using existing volume settings
From the Resources tab, select an allocated volume that has desired attributes for the new volume
to allocate, and click Allocate Like Volumes.
Managing storage resources in a SAN environment62
Prerequisites for allocating volumes
Before allocating volumes to a host you must verify that the host, and storage systems are registered

To allocate volumes to cluster hosts, verify that all cluster host names are displayed in the Allocate
Volume dialog box. Do this as an extra check to prevent an incorrect allocation.
5. Specify your volume allocation requirements.
6. Click Show Plan to check your volume allocation.
7. If the plan is correct, submit the task.
Managing storage resources in a SAN environment64
NOTE:
You can allocate volumes to cluster hosts that are not in a logical group. However, you must
ensure that your host selection is correct. Logical groups are strongly recommended.
8. Check for a Completed task status.
The same volumes have been allocated to individual hosts that belong to a cluster.
Allocating volumes by using a keyword search
A keyword search is a full or partial text search. For example, you can search for storage systems,
hosts, volumes, parity groups, THP/Smart pools, and logical groups by entering a full or partial name.
This provides an alternate method of navigating to a resource and performing volume allocation.
1. Enter a value in the search box on the tabs bar, and press Enter. All Resources is the default se-
lection. You can limit the scope of searched resources using the drop down menu.
NOTE:
As the number of searchable objects grows, identify a specific resource to search, for example
Logical Groups, to decrease search time.

About LUN path management
When you allocate a volume to a host, HP StorageWorks P9000 Command View Advanced Edition
Suite allows you to assign or edit LUN paths between one or more volumes and one or more hosts.
LUN paths provide volume access for the host by pairing storage ports and host ports. For example,
one or more storage ports can be mapped to one or more host ports (host bus adapters (HBAs)).
After volumes have been allocated to a host, you can edit existing LUN path information to add new
paths and/or delete existing paths from a list of allocated volumes in the Storage Systems tree, Hosts
tree, Logical Groups tree, and from a list of volumes returned from a search.
When initially allocating volumes and setting LUN paths, or editing LUN paths later, WWN nickname
information can be displayed to confirm the host port (HBA). Please note the following conditions for
displaying WWN nicknames:
• WWN nicknames become visible when storage system information is refreshed. If WWN nicknames
are updated on the storage system, another refresh is needed to ensure the latest information.
Refreshing host information, including host names and WWNs, does not update storage system
WWN nicknames in HP StorageWorks P9000 Command View Advanced Edition Suite.
• If several WWN nicknames (for example, as set on different storage systems) exist for a host HBA,
only one of the nicknames is displayed for that HBA.
• In addition to the edit LUN paths dialog, WWN nicknames are displayed in the LUN paths panel
during volume allocation, the LUN paths information panel during volume unallocation, and the
Volumes panel on the Resources tab.
Because allocated volumes belong to a specific host group, the same target host port is set for all
volumes in any given host group. Therefore, when adding or deleting a host port for one or more
volumes, you must select all of the volumes in that host group to maintain consistent LUN path
assignments for all volumes.
Editing LUN paths
You can add and delete LUN paths between storage systems and hosts.
1. On the Resources tab, expand the storage, hosts, or logical group trees to display volumes.
2. Select one or more volumes for which you want to edit LUN paths. Selected volumes should belong
to the same host group, and the host group should belong to a single storage system.
3. From your current tree click Edit LUN Paths, or click More Actions and select Edit LUN Paths to
display the Edit LUN Paths dialog box.
4. Use the graph or table view to map storage ports to host ports. In both views, you can use links
to view WWN nickname information to confirm the target host bus adapter (HBA).
a. In graph view, click on a storage port row to add it to the LUN Path Editor panel. Connect
the line to the target HBA. Another line is displayed, which you can connect to another HBA
or discard with a click.
b. In table view, select a storage port, then a host port row, then click Add to move the mapping
to Selected host Ports panel.
Note that if you add an incorrect mapping you can delete it by clicking on the connector line in
graph view, or using the remove button in table view, or you can cancel the dialog and start
over.
5. To delete an existing in use path as indicated by a green line in graph view, or by the 'In Use'
state in table view, do the following:
a. In graph view, click the green line. The line will now be gray and thin.

About unallocating volumes
You can unallocate volumes from clusters, or hosts. Unallocated volumes can be:
• Re-allocated (with existing data) to a cluster, or host that can recognize the existing data (file sys-
tem).
• Used for other storage requirements.
Unallocating a volume deletes all LUN paths that connect the volumes to the cluster, or host.
NOTE:
Unallocating volumes does not delete existing volume data by default. However, during the unallocation
there is an option to delete the volume (volume data is lost) and return it to unused capacity, or you
can delete the unallocated volume later. As a precaution, to retain volume data, back up volumes
before unallocating them (for example, for volumes to be re-allocated to a new host).
Unallocating volumes from hosts
Unallocated volumes can be re-allocated (with existing data) or can be made available for other
storage requirements.
Tasks to complete beforehand:
• Identify the name of the target cluster or host, and the volumes to unallocate.
• If necessary, backup data on the target volumes.
• Unmount all allocated volumes that you plan to unallocate. An IT administrator might have to
perform this task.
1. On the Resources tab you can unallocate volumes from several locations:
• From General Tasks, select Unallocate Volumes.
• Select a host OS, select one or more target hosts, and click Unallocate Volumes.
• Select a host OS, click a target host name to display volumes, select one or more volumes,
and click Unallocate Volumes. You can also search for a host, click the host name and go
directly to the volume list.
2. In the unallocate volumes dialog box, you will either select the host and host volumes to unallocate
and click Show Plan to continue, or if the host and host volumes were selected prior to launching
Managing storage resources in a SAN environment72
the dialog box, you will go directly to the plan summary. In both cases, you will see Advanced
Options in the dialog box that may be of interest.
3. Whether you clicked Show Plan, or went directly to the plan summary, do the following:
a. Review all plan information. If you clicked Show Plan and changes are needed, click Back.
If you went directly to the plan summary and changes are needed, click Cancel.
b. Enter a task name and description.
c. Schedule the task for now, or a later date and time.
d. If scheduled for now, select View task status to monitor the task when submitted.
e. Click Submit to queue the task.
4. On the Tasks & Alerts tab, confirm task completion. If status is not completed, click the task name

About replicating volumes (pair management)
Volume replication is used to make copies of critical data for volumes allocated to hosts. You can
make a local copy of a volume in the same storage system, or make a remote copy of a volume in a
different storage system.
Command View AE Suite provides several volume replication solutions based on pair management
requirements and related licensing:

Data mobility
An administrator can obtain information required to see the operating status of storage resources and
optimize data placement.
About data mobility
The Mobility tab provides information required to see the operating status of storage resources and
optimize data placement.
To efficiently use a storage resource, use the Mobility tab to optimize the data arrangement. In the
Mobility tab, information used to determine whether the data arrangement is appropriate is collectively
displayed. In addition, you can use the Mobility tab to centrally perform operations regarding moving
data such as data migration. To use the Mobility tab, you must first register a Tiered Storage Manager
license. Using Mobility tab information, you can evaluate and analyze whether the hardware tiers
are being used appropriately and whether the volumes are providing the expected performance.
Based on these results, you can optimize data placement by migrating data and setting up a Smart
Tiers Software tiering policy (which specifies the hardware tiers in which volumes are to be placed).
After completing these operations, check their effect from the Mobility tab and then perform any other
necessary data optimization operations. By repeating this process, the placement of data can be
optimized. The following figure shows the process of optimizing data placement.
User Guide 77
From the Mobility tab, data placement can be optimized from either the application (logical group)
perspective or from the THP/Smart pool perspective. To respond to requests from host or application
administrators, or to confirm whether Smart pools and storage resources are being used according
to the needs of each application, check the balance between the performance and the configuration
ratio of logical groups. To regularly monitor storage resources, or if there is a problem in the analysis
of logical groups, check the balance between the performance and the configuration ratio of each
THP/Smart pool. If there is a problem, you must check the operating status of each volume in the
THP/Smart pool and then optimize the configuration.
When periodically monitoring logical groups or THP/Smart pools during routine work, check the
ranking reports in the Mobility tab so you can efficiently find logical groups or THP/Smart pools that
have problems in their operational status.
The Mobility tab can be used to check the total capacity and usage rate for each logical group, THP/
Smart pool, or each volume in a logical group or THP/Smart pool. As with Smart pools, you can also
check which volumes are using the largest proportions of each hardware tier. In addition, the following
performance information can also be viewed:
• Quantity of I/O operations compared to the calculated maximum number of I/O operations
In addition, if linked with HP StorageWorks P9000 Performance Advisor software, the following
performance information can also be viewed:
• Throughput (IOPS) for THP/Smart pools, volumes, and hardware tiers
• Past volume performance data (to look for trends)
• Response time of the volume
• Busy rate for parity groups
For details on linking to HP StorageWorks P9000 Performance Advisor software, see the HP P9000
Command View Advanced Edition Suite Software Administrator Guide.
NOTE:
If HP StorageWorks P9000 Performance Advisor is not linked, or information cannot be obtained
due to storage system type, or the HP StorageWorks P9000 Performance Advisor software version,
hyphens are displayed in performance information columns.
From the Mobility tab, the following operations can be performed to optimize data placement:
• Configuration and editing of aSmart Tiers Software tiering policy
• Migration of volumes
• Manually starting or stopping the monitoring and relocation of Smart pools
• Editing tier relocation of Smart volumes
• Expanding, shrinking, or changing of the settings for THP/Smart pools
• Expanding THP/Smart volumes and reclaiming zero pages
By creating tiers of volumes or THP/Smart pools based on use or performance, you can migrate data
to volumes or THP/Smart pools that match the relevant conditions simply by specifying a tier as the
migration target.
Reports for logical groups displayed in the Mobility tab
The following ranking reports for logical groups are displayed in the Mobility tab:
• Bottom 10: Logical Groups with High Response Time
Managing storage resources in a SAN environment78
Checks for logical groups including volumes whose response time is slow. Used to determine logical groups which do not satisfy required performances. This ranking is displayed only when you
have the license for HP StorageWorks P9000 Performance Advisor software.
• Top 10: Logical Groups with Lowest Unused Capacity
Checks for logical groups that have little unused capacity left for the allocated THP/Smart volumes.
Used to determine logical groups which do not have enough capacity.
• Top 10: Logical Group Used Capacity by Drive Types
Checks for logical groups that use a large amount of capacity by drive type. Used to determine
whether an unexpected volume is occupying a high-speed drive or logical groups which have invalid data arrangements.
The following information is displayed when a logical group is selected:
• Summary
Provides summarized information in a list, such as the number of volumes and the total capacity
of a logical group, or the last update date. Based on this information, you can review the usage
status of the storage resources in the logical group.
• Drive Type Summary
Checks whether the logical group has the necessary capacity. Checks the total capacity of the
volumes and the used capacity of each drive type within the logical group.
• Drive Type Distribution
Checks how many of each drive type is used for each THP/Smart pool that is included in a logical
group. Used to check whether the configuration of the hardware tier is appropriate.
Reports for THP/Smart pools displayed in the Mobility tab
The Mobility tab displays several types of reports, each with its own purpose.
Ranking reports for THP/Smart groups displayed in the Mobility tab are as follows:
• Top 10: Pools with the Highest Used %
Checks for THP/Smart pools with a high capacity usage rate to determine THP/Smart pools that
need pool expansion or data migration.
• Top 10: Pools with the Highest Subscription
Checks for THP/Smart pools with a high reservation rate to determine THP/Smart pools that need
pool expansion or data migration.
• Top 10: Tiers with the Highest Performance Utilization
Checks for hardware tier configurations with high ratio of actual I/O operations to the calculated
maximum number of I/O operations. Used to determine Smart pools that include hardware tier
configurations with saturated performance.
The information displayed when each THP/Smart pool is selected is as follows:
• Summary
Summarizes information in a list, such as the total capacity and usage of THP/Smart pools, and
the reservation rate. Based on this information, you can review the usage status of the THP/Smart
pool.
If a Smart pool is selected, the following information can also be viewed:
• Tier Summary
User Guide 79
Checks information such as drive type, drive rotational speed, and capacity usage rate of each
hardware tier. Based on this information, you can review the usage status of hardware tiers. Note
that this summary only appears for Smart pools.
• Capacity Utilization
Checks the total capacity and used capacity of the Smart pools for each hardware tier. Used to
check whether the Smart pool has the necessary capacity and which hardware tier needs more
capacity added to it. This summary only appears for Smart pools.
• Performance Utilization
Checks the ratio of actual I/O operations to the calculated maximum number of I/O operations
for each hardware tier. Used to check for hardware tiers with performance in a saturated state
requiring optimization (editing the tiering policy, or data migration). This summary only appears
for Smart pools.
• Top 10: Volumes Sharing Tier Capacity
Checks the usage ranking of volumes that have the largest use capacity in each hardware tier.
Based on this information, you can check whether data placement is appropriate, for example by
checking whether an unexpected volume is occupying a high-speed drive. This summary only
appears for Smart pools.
• View Tier Properties
Checks the page access distribution per average number of I/O operations, which is based on
the monitoring information of Smart pools.
Based on this information, you can check whether the hardware tier configuration or tiering policy
settings are appropriate.
From the page access distribution for Smart pools, you can narrow the range of displayed items
to only tiering policies or only Smart volumes, as required.

Data migration
This module describes data migration.
About data migration
Data migration involves moving data from one set of volumes to another set of volumes or THP/Smart
pools, including those in externally-connected storage systems. For example, you can migrate data
when your volume performance decreases or your environment changes. When relocating data based
on the results of performance monitoring for volumes being used by servers and applications, or when
migrating data from an old storage system to a newly set-up storage system, the data in multiple
volumes can be migrated to other volumes or THP/Smart pools.
The source volume can be selected by host or by logical group. The source volume also can be selected
from some of the volumes allocated to a host some of the volumes in a logical group, some of the
volumes in a tier. Migration source volumes can also be selected from volume search results. If a
volume that cannot be migrated is included in the selected volumes, that volume is excluded from
migration and only volumes that can be migrated, will be migrated.
Migration targets are selected from tiers, THP/Smart pools, or resource search results. If THP/Smart
pools are selected, THP/Smart volumes with the same capacity as the migration-source volumes are
automatically created. The existing THP/Smart volumes also can be specified as migration targets.
Note the following:
User Guide 81
• When the migration source and the migration target are selected, individual pairs of migration
source volumes and migration target volumes (or THP/Smart pools) are automatically created.
Although, you can change these pairs, pairs of volumes that cannot be migrated will not be created.
• During migration, data can still be accessed.
• When data migration is completed normally, the LDEV ID and host I/O of the migration source
volumes are changed to those of the migration target volumes. The procedure for accessing migrated
data is not changed before or after migration.
• If linked with HP StorageWorks P9000 Performance Advisor software, parity group busy rate for
the migration source volume and migration target volume can be checked.
• After migrating, you can delete the data of the source volumes.
• After volumes are migrated to a THP/Smart volumes, unused capacity in the target volumes is re-
turned to the pool (zero page reclaim) if the zero page reclaim option is on.
• You cannot work with volumes (such as copy pair or volume allocation) until the migration tasks
are completed.
You must have a Tiered Storage Manager license registered to perform Data Migration.
For details about data migration in Legacy mode, using migration groups earlier than v7.1.1, see
“About Legacy mode” on page 149.
Notes on performing data migration
The number of volumes that are candidates for migration target volumes are narrowed down and
displayed when selecting a migration target volume. If you want to display all the volumes, in the
migration.properties file on the Device Manager server set a value for the
migration.plan.candidateVolumeCountLimit property.
For details on the properties file, refer to the HP P9000 Command View Advanced Edition Suite
Software Administrator Guide. To avoid insufficient memory, we recommend that you use the default.
The maximum number of volumes that can be displayed as migration target candidates is 2,000
volumes. Exceeding this value will produce an error.
The maximum number of volumes that can be displayed as migration source candidates is 500
volumes. Exceeding this value will produce an error.
Data migration tasks take a long time from start of execution to completion. This might affect the
performance of access from hosts to target volumes. To avoid executing such tasks while the access
frequency is high, check the time required to complete the tasks and set a task execution schedule
before registering the tasks. Actual required time might differ considerably in cases such as performing
migration for the first time, migrating a volume smaller than 170 GB, or migrating many volumes at
the same time.
When storage systems or hosts are under a heavy load, migration might fail. In this case, reduce the
load on the storage systems, and then perform data migration again.
If data migration fails, the integrity of data on the migration target cannot be ensured. Therefore, data
migration must be performed again.
If a data migration fails, and operations for the migration target such as re-execution of data migration
and volume allocation cannot be performed, the storage system must be refreshed.
Conditions for data migration
Data migration conditions include conditions that apply to all volumes (volume migration requirements),
and conditions that depend on the type of volume (volume migration requirements related to volume
type).
Managing storage resources in a SAN environment82
For some volumes, when you try to select those volumes as migration-source volumes, the reasons
why they cannot be selected as migration-source volumes are displayed on-screen.
Volume migration requirements
All volumes for which data migration is to be performed must meet the following conditions:
• Migration-source and migration-target volumes exist within one of the following storage systems
(chassis):
• P9500 Disk Array
• XP24000/XP20000
• XP12000/XP10000/SVS200
• The emulation type, number of blocks, and size are the same for the source and target migration
volumes. However, note the following exceptions:
• If the micro version of XP24000/XP20000 is 60-03-20-00/00-xx or later and if both the migration source and the migration target volumes are THP/Smart volumes, the emulation type
can be between OPEN-V and OPEN-0V.
• If a volume whose emulation type is OPEN-V is a normal volume, and if the size of a migration
target volume is larger than a migration source volume, a volume that has the same size of the
migration source volume is re-created. The remaining capacity can be reused. If you set a
value for the property migration.plan.candidateCapacityGroupDisplayMaxCount
in the migration.properties file, you can specify how many volumes with a larger capacity
than the migration source volume to display, in addition to the volumes with the same capacity
as the migration source volume.
• The LDKC:CU:LDEV number for the volume is in the range from 00:00:00 to 00:FF:FF
• Volumes can be accessed, and are not reserved by other programs, Device Manager, or tasks.
• If the emulation type is not OPEN-V, and both the migration source and the migration target
volumes are normal, or both are CVS volumes.
Volume migration requirements related to volume type
Whether you can select a volume as a migration source or migration target depends on the volume
type. The following table shows which volume types can and cannot be selected as migration sources
and targets.

Notes:
1. When the migration source volume is a LUSE, a migration target must be selected for each volume that
constitutes the LUSE. Migration target volumes must also satisfy the following conditions:
• All of the migration target volumes are internal volumes, or all are external volumes.
• The I/O suppression mode, cache mode, and CLPR of all migration target volumes are the same.
• Migration target volumes are not THP/Smart volumes.
Also, for Tiered Storage Manager to automatically create pairs for migration sources and migration targets,
we recommend that the following conditions also be met:
• If the migration target volumes are external volumes, all of the volumes are in the same external storage
system.
• The RAID level, drive type, and SLPR (storage management logical partition) of all migration target
volumes are the same.
Note that if you are migrating a LUSE volume of an XP24000/XP20000 storage system for which the
micro version is earlier than 60-05-12-00/00, you must not perform I/O operations on the volumes while
migration is being executed.
2. The migration-source volumes and migration target volumes or pools are in different THP/Smart pools.
3. The following conditions must be satisfied:
• The status is not blocked.
• The THP/Smart pool has more unused capacity than the migration-source volumes.
• Used THP/Smart pool capacity does not exceed both used thresholds 1 and 2 (even after a migration
is performed).
• THP/Smart pool subscription does not exceed the subscription warning and subscription limit (even
after a migration is performed).
• When selecting migration-target resources, if the option to create new THP/Smart volumes is selected,
the number of virtual volumes in the THP/Smart pool is less than the limit (P9500 Disk Array: 63,232;
XP24000/XP20000: 8,192).
4. The CLPRs for the migration target and migration source are the same.
5. If an external storage system is locked (not Read/Write), it cannot be a migration source or migration
target.
6. Volumes with virtual IDs specified cannot be selected as migration target volumes when:
• The migration target is a THP/Smart pool, and Create new THP volumes is selected in the migration
target creation options.
• The specified capacity differs from the capacity of the migration source.
Reasons why volumes cannot be selected as migration sources
If a volume cannot be made a migration source and the reason for it is displayed, in the Data Migration
wizard, a character string is displayed in the Migration Restriction column for Selected Column on
the Migration Source page. The following table shows the character strings and corresponding reasons
why a volume cannot be made a migration source.

User Guide 89
Prerequisites for migrating data from an SMI-S Enabled storage system to another storage system
You can migrate data between an old and new storage system for abolishing or merging systems by
using the external storage connection function (Universal Volume Manager). The figures below provide
an example of migrating data to HP XP24000 when the SMI-S Enabled storage system is abolished.
To perform migration, use the GUI or CLI to migrate data by the system.
Migrating data from an SMI-S Enabled storage system to another storage system
You can migrate data from an SMI-S Enabled storage system to another storage system.
Tasks that must be completed beforehand:
• The Device Manager CLI is set up.
• A Tiered Storage Manager license is registered.
• The Tiered Storage Manager CLI is set up (if necessary).
• The port of the SMI-S Enabled storage system is connected to the External port of the storage system
via Fibre Channel.
Managing storage resources in a SAN environment90
• The volumes of the SMI-S Enabled storage system are assigned to the External port (performed by
the management tool of the SMI-S Enabled storage system).
Information that should be obtained beforehand:
• Name or IP address of the allocation target host.
• The WWN and LUN associated with the migration source SMI-S Enabled storage system that was
assigned to the External port.
For details about the values specified for the parameters and syntax of each CLI command of Device
Manager and Tiered Storage Manager to be used for operations, see the HP P9000 Command View
Advanced Edition Suite Software CLI Reference Guide and the HP P9000 Tiered Storage Manager
CLI Reference Guide.
1. Register the migration target storage system and the migration source SMI-S Enabled storage
system in HP StorageWorks P9000 Command View Advanced Edition Suite. Use the GUI to register the storage systems, or execute the AddStorageArray command (Device Manager CLI).
NOTE:
Registering or updating a storage system might take a long time depending on its configuration
or scale, so you need to perform these operations systematically.
NOTE:
If the migration target or source storage system has already been registered, you need to update
the migration target or source storage system in order to obtain the latest configuration
information.
2. Stop the hosts to which the storage systems are connected.
Note that steps 3 - 4 below need to be performed while the host is stopped, so you need to make
a plan in consideration of host operations.
3. Map the volumes of the migration source SMI-S Enabled storage system to the migration target
storage system as external volumes.
Execute the AddExternalArrayGroup command (Device Manager CLI).
4. Allocate the external volumes mapped to the migration target storage system to the host.
Use the GUI to allocate the volumes, or execute the AddLun command (Device Manager CLI).
5. Start the host, and then change the target that the host (applications) accesses from the migration
source storage system to the migration target storage system.
Perform this step by using the configuration tools of the host while applications are stopped.
6. Migrate data in the external volumes (migration source) to an internal volume of the migration
target storage system (data migration). Use the GUI to migrate data, or execute the following
commands (Tiered Storage Manager CLI):
• CreateStorageTier command
• CreateMigrationGroup command
• CreateMigrationPlan command
• CreateMigrationTask command
• ExecuteTask command
7. Unmap the external volumes (migration source) from the migration target storage system.
User Guide 91
Execute the DeleteExternalArrayGroup command (Device Manager CLI).
8. Delete the migration source SMI-S Enabled storage system from the management targets of HP
StorageWorks P9000 Command View Advanced Edition Suite.
Use the GUI to delete a storage system, or execute the DeleteStorageArray command (Device
Manager CLI).
The data of the migration source SMI-S Enabled storage system can be used as an internal volume
of the migration target storage system. The migration source SMI-S Enabled storage system can be
removed.
Managing tasks
This module describes how to manage tasks.
About tasks
When you perform any operation, the operation is registered as a task.
• Tasks can be performed immediately or at a specified date and time. This allows the storage ad-
ministrator to schedule storage operations appropriately.
• You can check the progress or the results of all previously executed tasks on the Tasks & Alerts
tab.
• The schedule of a task that is waiting can be changed.
• Specifying an email address when registering migration tasks enables email notification for migra-
tion task completion (tasks whose status is success, failure, or stopped).
TIP:
An email notification makes it unnecessary to monitor the progress of a task. This setting is used
in cases where you want to verify the execution results for a task, or when it is necessary to contact
a server administrator or application administrator regarding changes to storage system settings,
or when you plan to execute a task that will take a long time to finish.
• When a task is registered, Command View AE Suite reserves any resources that the task requires
(such as, volumes, parity groups, pools, host groups), and denies access to other operations until
the task either completes or is cancelled.
• Data migration tasks and data placement profile tasks can be stopped during execution.
• If the server stops before a task starts, the task will run the next time the server starts. If the server
stops while a task is running, the task will fail. Scheduled tasks can be rescheduled after the server
is restarted.
NOTE:
Information about previously run tasks is automatically deleted, starting with the oldest task, after the
number of tasks exceeds 100,000. Tasks can also be deleted manually. Until the task is complete, do
not perform operations on any volume included in the task by using HP StorageWorks P9000
Command View Advanced Edition Suite or any other program.
Managing storage resources in a SAN environment92
Viewing task status
Viewing the status of a task allows you to see if a task has completed, as well as other details.
1. From the Tasks & Alerts tab, Tasks & Alerts pane, click All Tasks.
2. You can check the task Status column from the Tasks tab, or History tab, to determine if a task
completed.
3. Click the task name link in the Tasks column to review the Task Details dialog box. If a task has
failed, look for a diagnostic message (Message field).
Rescheduling tasks waiting to be executed
You may reschedule tasks waiting to be executed.
1. On the Tasks & Alerts tab, select All Tasks.
2. Select the waiting task you want to reschedule from the Tasks tab and click the Reschedule Tasks
button specify a new schedule from the dialog box.
3. You can now either execute the rescheduled task or confirm that the waiting task is rescheduled
by viewing the Tasks list.
Stopping running data migration or data placement profile tasks
Data migration or data placement profile tasks can be stopped during execution, in the following
ways:
• Normal stop - A task stop request is issued and processing that is currently being performed is
continued. For data migration, tasks are stopped when data moving processing completes. For
Data Placement Profile operations, tasks are stopped when processing for each storage system
completes. Processing that has not been started is stopped. It might take a long time after a task
stop request is issued before the task stops completely.
• Immediate stop - If you select the Stop the tasks immediately check box (immediate stop), or if a
task is performed that searches for inconsistent data placement profiles when a storage system is
refreshed, all processes are stopped immediately. For data migration tasks, since data that was
being migrated remains in the target volume, the user must delete the data in the target volume.
Therefore, we recommend that you use immediate stop only for emergencies.
The storage administrator checks the task progress and results in the Tasks & Alerts tab allowing the
schedule of a task that is waiting to be changed.
1. In the Tasks & Alerts tab, select All Tasks.
2. Select one or more running tasks that you want to stop, and click Stop Tasks.
3. In the confirmation dialog box, click OK.
4. In the task list window, confirm that the status of the task is stopped.
NOTE:
To access the Task Details dialog box to see the point at which a task was stopped, click All Tasks
in the Tasks & Alerts tree and click the task name link in the summary column of the Tasks tab.
Canceling scheduled tasks
You can cancel scheduled tasks that have not yet started.
User Guide 93
NOTE:
You can view the status of a task while it is running or scheduled to run. You can only cancel tasks
that are in Waiting status.
1. On the Tasks & Alerts tab, select All Tasks and select a task from the task list.
2. Click Cancel Tasks.
3. Upon cancellation of a task the status of the task appears as Canceled.
Moving tasks to the History tab
You can move completed, failed, stopped, or canceled tasks from the Tasks tab to the History tab.
For example, you could move completed and cancelled tasks to the History tab and keep submitted,
stopped, and failed tasks in the Tasks tab until the tasks run to completion, or are resolved. Note that
moved tasks cannot be moved back to the Tasks tab.
1. From the Tasks & Alerts tab, select All Tasks.
2. Select one or more tasks on the Tasks tab, and click Move to History.
The tasks are moved to the History tab.
TIP:
To delete tasks from the Tasks or History tabs , select one or more tasks and click Delete Tasks.
Managing storage resources in a SAN environment94
4 Grouping resources
This module describes how to group logical groups and storage tiers (resources).
Managing logical groups
This module describes how to manage logical groups.
About logical groups
A logical group is a group of hosts and volumes. A storage administrator creates logical groups and
assigns hosts and volumes to each logical group.
Logical groups allow you to:
• Create summary reports that indicate the current resource use in a storage environment by organ-
ization.
If you manage an entire system, you can create logical groups to generate usage summary reports
for each organization that uses storage.
• Monitor volumes and perform storage system operations by grouping managed resources (hosts
and volumes).
If you manage part of a system, you can categorize volumes according to the organizations that
use the storage. Grouping and categorizing volumes makes finding volumes easier and allows
you to perform daily operations for volume resources.
You can register multiple hosts or volumes to a logical group at one time by specifying a range of IP
addresses, or multiple items, such as operating system type and drive type. You can also change the
hierarchy of existing logical groups, or add and remove hosts and volumes. The same host(s) or
volume(s) can be registered to different logical groups. If a Tiered Storage Manager license has been
registered, use the Mobility tab to check the operation status of volumes per logical group or optimize
data arrangements. To efficiently find logical groups that have usage problems, use the Mobility tab
to check their rankings (e.g. logical groups that have small amount of unused capacity or use a large
amount of capacity per drive type).
Creating logical groups
Tasks to complete beforehand:
• Identify that the host to be assigned to a logical group is a normal host, a virtualization server, or
a virtual machine registered as a host. The volumes allocated to the host are automatically assigned
to the logical group.
Note the following restrictions:
• Mainframe volumes (MF-Vols) cannot be assigned to a logical group.
• Child groups cannot be created below host or volume groups. Child groups can be created only
below folders.
User Guide 95
1. On the Resources tab, select Logical Groups.
2. Click Create Logical Group.
3. Create a folder for each new logical group:
a. Click Create Logical Group.
b. Enter the appropriate information.
c. Click OK.
d. Repeat for each new folder required.
4. To create a hierarchy of logical groups, repeat step 3.
On the Resources tab, click Logical Groups and confirm that the logical groups you created appear.
TIP:
To delete logical groups, select the logical groups to be deleted, and click Delete Logical Groups.
Viewing logical group reports
You can view summary reports for specified logical groups.
1. On the Resources tab, click Logical Groups.
2. Expand the tree and select the target logical group.
Editing logical groups
You can edit a logical group to change the parent group or change the host and volume settings.
1. On the Resources tab, click Logical Groups.
2. From the Logical Groups list, select the logical group you want to edit.
3. Click Edit Logical Group.
4. Change the parent group or change the host and volume settings.
5. Click OK.
6. Confirm the change by selecting the logical group and viewing the logical groups summary or
the host or volume list. If you change the parent logical group, you can confirm the new hierarchy
by reviewing the logical groups tree.
Performing operations from a logical group
You can perform operations on storage systems by starting from a logical group.
1. On the Resources tab, select Logical Groups.
2. Expand the tree and select the target logical group.
3. Select a host or volume.
4. Click on the operation to perform (Allocate Volumes, Unallocate Volume, Edit LUN Path, or Edit
Label).
5. In the task list, confirm that the task is completed.
Managing storage tiers
This module describes how to manage tiers.
Grouping resources96
About tier-based storage management
In HP StorageWorks P9000 Command View Advanced Edition Suite, you must have a Tiered Storage
Manager license to perform tier-based storage management operations.
In a tier-based storage management system, storage system resources are grouped and managed in
tiers. Tiers can be created for volumes or for HP StorageWorks P9000 Thin Provisioning (THP/Smart)
pools to allow high-capacity resources to be centrally managed.
Tiers allow you to allocate data according to its purpose. This allocation can be done by grouping
drives in a storage system by type, or by creating groupings of particular tasks or functions. For
example, you can allocate frequently accessed data to a tier of high-reliability drives or storage
systems.
You can also use storage system resources more efficiently by storing data that is only for archive
purposes on a tier of SATA drives or older storage systems. A volume can also have a volume belong
to multiple tiers.
When you are managing a large variety of resources in tiers, you can check the performance status
of all the resources in the tiers at the same time, and you can select the migration-source and
migration-target volumes for data migrations from the tiers. By selecting tiers that match all the
requirements when volumes will be allocated to hosts, you can allocate all the necessary volumes
from the selected tiers at the same time.
Values to ensure acceptable tier performance
The values below ensure the operation of Tiered Storage Manager. Performance might slow down
or memory might become insufficient if a value exceeds these values.

User Guide 97
Confirm that the tier is included for the storage system selected in the Tiers tree.
TIP:
To remove tiers, select the tiers to be deleted, and click Delete Tier.
Expanding a tier
Before expanding a tier, verify that:
• A Tiered Storage Manager license is registered
1. On the Resources tab, Resources pane, click Tiers.
2. Expand the tree, select the storage system with the tier you want to expand, and click Edit Tier.
3. Specify the appropriate values.
4. Click OK.
5. Confirm that the tier has expanded.
Managing resource labels
This module describes how to manage resource labels.
About managing resource labels
User defined resource labels can be assigned to volumes and THP/Smart pools. Specifically, resource
labels can be volume labels, or THP/Smart pool names.
Resource labels help users:
• Search for volumes or THP/Smart pools
• Differentiate between listed volumes or THP/Smart pools
• Confirm the correct resource is being acted upon
When resources are located with a label search, tasks can be performed including:
• Allocating volumes or THP/Smart pools
• Editing volume LUN paths
Note that resource labels can be created using:
• Device Manager
• Remote Web Console
For storage systems where resource labels have already been configured using Remote Web Console,
you can apply (import) the resource labels to Device Manager in a batch operation.
If Device Manager and Remote Web Console are both actively used, and Command View AE Suite
is the primary management software, labels set in Device Manager can be applied (exported) to
storage systems managed by Remote Web Console.
Grouping resources98
NOTE:
Due to differences between Device Manager and storage systems, incompatible character type or
string length issues will be reported with pop-up messages. Use the message to resolve resource label
naming issues.
Editing resource labels
You can create or edit volume labels or THP/Smart pool names.
1. In the Resources tab, expand Storage Systems, and list volumes or THP/Smart pools.
2. To edit a volume label, select Edit Labels, and to edit the name of a THP/Smart pool select Edit
Pool.
3. Edit the necessary settings, and submit the task.
4. Check the task execution results in Tasks & Alerts.
Confirm changes in the volume and THP/Smart pool list.
TIP:
To apply the current labels to the storage system with no changes, specify the following settings:
• For volume labels, without entering new labels, select Reflect current labels to the storage systems
radio button.
• For THP/Smart pool names, without editing the pool names, select
Reflect this pool name to the storage system check box.
Searching resource labels
You can search, filter and sort on resource labels to locate volumes or THP/Smart pools and perform
actions on them.
1. Locate volumes or THP/Smart pools by using one of the following methods:
• Using the search box, enter a volume label or THP/Smart pool name, and perform a search.
You can use Search Keyword for to specify the resources you want to search, for example
Volumes.
• From the search box, you can also search volume labels by using More Searches, selecting
Volume, and selecting the category Label from the Advanced tab.
• To filter, from the Resources tab expand the tree to display the list of volumes or THP/Smart
pools, and click Filter to specify the volume label or THP/Smart pool name.
• To sort, from the Resources tab expand the tree to display the list of volumes or THP/Smart
pools, and click Label or Name column headings to sort by volume label or THP/Smart pool
name.
2. Select volumes or THP/Smart pools from the search, filter, or sort results.
3. Perform the desired task.
User Guide 99
Importing storage system resource labels
In an environment where storage system labels have already been set using Remote Web Console,
you can apply (import) the storage system labels to Device Manager.
NOTE:
Applying storage system labels overwrites all the volume labels and THP/Smart pool names of Device
Manager for the selected storage system.
1. From the Resources tab, expand the Storage Systems tree and select the storage system whose
labels you want to apply.
2. Click Refresh Labels.
3. Select the resource labels to apply, and submit the task.
4. Check the task execution results in Tasks & Alerts.
Make sure the labels are changed in the volume list, and that pool names are changed in the THP/
Smart pool list.
