external authentication server.
About configuring P9000 Command View AE Software
The following graphic illustrates the flow for getting started with P9000 Command View AE Software.
About storage resource settings
Storage systems and hosts must be registered for storage resources to be managed by P9000 Command
View AE Suite. A host can be managed by its group based on its organization and user tasks by
using logical groups. Below is shown the flow for setting up storage resources.
About users and access control settings
After users are registered, you can limit the scope of allowed operations for each user by configuring
access control settings for users and other storage resources.
Overview14
To set access control:
1. Create resource groups
2. Create user groups
3. Assign resource groups and roles to user groups
About developing a virtualized storage environment
Virtualization of storage allows a larger than physical storage capapcity for a stand-alone host, thus
reducing equipment and operational costs as well as permiting the integration heterogenous storage
devices. The following graphic illustrates the flow for setting up a virtual storage environment.
About allocating storage
To be prepared against any possible loss of data due to equipment failure, it is important to replicate
critical data by allocating storage volumes based on logical groups. The following graphic illustrates
the flow of allocating storage resources.
About managing storage resources hierarchically
Tiers are created by grouping volumes and THP pools based on their usage, performance, and
reliability. By migrating volumes, data can be placed into appropriate tiers based on how often the
data is accessed. This allows data to be migrated collectively by groups while business is being
continued, for instance when replacing storage systems. The task flow for managing storage resources
by placing them in hierarchies is shown below.
User Guide 15
About monitoring storage
You can check the status of storage resources to detect problems and output reports to a CSV file
containing search results or configuration and capacity information about hosts, logical groups, and
other storage resources. This information can be used to migrate volumes or add THP 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:
Overview16

This module describes how to register storage systems and hosts.
Registering storage systems
This module describes how to register storage systems.
About registering a storage system
Registering a storage system enables you to monitor and manage storage resources, such as volumes,
parity groups, THP pools, and external storage connections. Information about a storage system can
be changed after the storage system is registered.
When you specify an IP address and authentication information for a storage system in the network,
the storage system is discovered based on the specified information. The registered storage systems
can be used as resources.
Prerequisites for registering a storage system
Before registering a storage system, verify the following:
• Target storage system is connected to the network.
• Target storage system type (device type).
• Target storage system IP address (IPv4 or IPv6) or host name.
• User name and password of the storage system for Password Protection or Account Authentication
(mid-range storage systems).
• User name and password of the storage management tool such as Remote Web Console (HP
P9500, XP24000/XP20000, or XP12000/XP10000/SVS200) . If you have a different storage
system, then use your user name and password for Account Authentication or Password Protection.
Registering a storage system
Register a storage system to monitor and manage it from P9000 Command View AE Software, along
with the other registered storage systems and hosts.
Before you perform this task, review “Prerequisites for registering a storage system” on page 17.

2. On the Storage Systems tab, click Add Storage System.
3. Specify the appropriate information.
4. Click OK.
5. Check the Data Collection Tasks tab to verify that the task has completed successfully.
User Guide 17
6. When the task completes, confirm that the storage system appears on the Storage Systems tab
of Managed Resources.
Or, you can confirm that the storage system name appears in the Storage Systems tree on the
Resources tab.
Prerequisites for changing storage system information
Before changing storage system information, make a note of:
• Target storage system name.
• Storage system IP address (IPv4, IPv6) or host name.
• Management tool such as Remote Web Console (HP P9500, XP24000/XP20000, or XP12000/
XP10000/SVS200) .
• User name and password of the storage system.
For other storage systems, use the user name and password for Password Protection or Account
Authentication.
Changing storage system information
You can modify the IP address or login username 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 username and password can be modified.
To modify information about a storage system:
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.

3. Click Refresh Storage Systems and then click OK.
4. Check the Data Collection Tasks tab to verify that the task has completed successfully.
5. When the task completes, confirm that the storage system information is updated on the Storage
Systems tab of Managed Resources.
Or, you can confirm that the storage system information is updated in the Storage Systems tree
the Resources tab.
Registering hosts
This module describes how to register hosts.
About registering a host
Registering hosts lets you monitor and manage them along with the other registered hosts and storage
systems.
The following hosts can be registered:
• Normal hosts: hosts in an environment where no virtual software is installed
• Virtual servers: hosts in a physical environment where virtual software is installed
• Virtual machines: hosts in a virtual environment created with virtual software
To register a host, specify the IP address and authentication information so can discover it automatically,
or you can add a host manually by specifying the WWN. Virtual server hosts must be registered
manually. Information about a host can be changed after it has been registered.
If you register a host by specifying its IP address and authentication information, the total capacity of
volumes that are allocated to the host can be automatically acquired only if the storage system that
provides the volumes is registered.
You can view information about registered hosts on the Resources tab.
Conditions for acquiring the WWN
If the specified IP address range includes a host with a WWN that is registered, or includes multiple
hosts that have the same WWN, which host acquires the WWN depends on the following conditions:
• A host detected by VMware® ESX (VMware ESX and VMware ESXi) has top priority.
• A host detected by a Device Manager agent has priority over a host detected by the Host Data
Collector.
• If multiple hosts with the same WWN are detected by VMware ESX, the host that was registered
most recently acquires the WWN. The same condition applies for hosts detected by Device
Manager agents. For hosts detected by the Host Data Collector, the host that was registered first
maintains the WWN.
Prerequisites for registering a host
• Target host is connected to the network.
• Target host IP address (IPv4).
• To detect multiple hosts at the same time, specify a subnet or range of up to 256 IP addresses, or
specify individual IP addresses.
User Guide 19
• To register a virtual server, an IPv6 address also can be specified. However, multiple hosts cannot
be detected at the same time for an IPv6 address.
• User name (who must have Administrator or superuser permissions) and password for logging on
the host.
Although you can modify host settings for sudo, if you specify a user other than a root user, you
must configure the required settings for the environment when information about the host is collected
only through a general user account. For more information on these settings, see the HP Storage-
Works P9000 Command View Advanced Edition Suite Software Administrator Guide.
• Host name.
• Unregistered WWN.
• Register virtual server information into the Device Manager (if registering virtual servers). For details
on the system requirements for virtual servers, see the HP StorageWorks P9000 Command View
Advanced Edition Suite Software Administrator Guide.
Registering a host
Register a host to monitor and manage it from P9000 Command View AE Software, along with the
other registered hosts and storage systems.
Before you perform this task, review “Prerequisites for registering a host” on page 19.
To register a host:
1. On the Administration tab, select Managed Resources.
2. On the Hosts tab, click Add Hosts.
3. Select Discover Hosts or Add Host Manually.
4. Specify the appropriate information.
5. Click OK.
6. Check the Data Collection Tasks tab to confirm that the task has completed successfully.
7. When the task completes, confirm that the host name appears on the Hosts tab of Managed
Resources.
Or, you can confirm that the host name appears in the Hosts list displayed by using the Hosts
tree on the Resources tab.
Prerequisites for changing host information
Before changing host information, note the following:
• Target host IP address (IPv4).
• If registering a virtual server, the IPv6 address also can be specified.
• User name (who must have Administrator or superuser permissions) and password for logging on
the host.
Sudo users do not have to be root users. However, if you specify a user other than a root user,
you must configure the required settings for the environment when information about the host is
collected. Do this by using a general user account. If registering a virtual server, the IPv6 address
also can be specified. For more information on these settings, see the HP StorageWorks P9000
Command View Advanced Edition Suite Software Administrator Guide.

Changing host information
You can change the information that P9000 Command View AE Software displays for registered
hosts.
To change information about registered hosts:
1. On the Administration tab, select Managed Resources.
2. On the Hosts tab, select the host, or hosts, you want to edit.
3. Click Edit Hosts.
4. Modify 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 Hosts list is updated.
About scanning and discovering hosts
Scanning for hosts creates a host whose name is the host group name for each host group name in
the storage system.
Adding a host by scanning automatically registers to the created host any WWNs that have been
previously registered to the discovered hosts.
NOTE:
Only WWNs that have not been previously registered for a host in HP P9000 Command View
Advanced Edition Suite products are registered for the created hosts.
Prerequisites for scanning for hosts
Before scanning for hosts, verify the following:
• The name of the host group is the same as the actual host, and the WWN name for that host is
set for LUN security.
• Only a single host can be related to each host group.
• A LUN Manager, or LUN Management, must be installed on the target storage system.
Scanning for new hosts
Before you perform this task, review the “Prerequisites for scanning for hosts” on page 21.
To scan for new hosts:
1. On the Administration tab, select Managed Resources.
2. On the Hosts tab, select the More Actions pull-down menu and select Host Scan.
3. Specify the appropriate information and run the host scan.
User Guide 21
About merging hosts
WWN names that are registered to multiple hosts can be merged into one destination host. The source
host will be deleted upon completion of the merge.
Information about WWN names are also merged. If the host that is monitored by the Host Data
Collector or Device Manager agent is merged as a source host, the source IP address will not be
migrated.
Prerequisites for merging hosts
Before you merge hosts, the destination host cannot be:
• mainframe
• virtual
• not registered with a WWN
Merging hosts
To merge hosts:
1. On the Administration tab, select Managed Resources.
2. On the Hosts tab, select the target host and from the More Actions pull-down menu, select Merge

Virtualizing storage
This module describes how to virtualize storage.
About virtualizing volumes
Virtualizing volumes is the process of mapping volumes in a source storage system to a target storage
system. The volumes in the source storage system (registered and referred to as external volumes)
can then be managed in the same way as the volumes in the target storage system (registered and
referred to as internal volumes).
Virtualizing volumes allows you to use P9000 Command View AE Software to centrally manage
volumes in multiple source storage systems from a single 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.
NOTE:
To virtualize volumes, External Storage Software must be installed on the target storage system.
Prerequisites for virtualizing volumes
Before virtualizing volumes, verify the following:
• The internal and external storage systems are registered in P9000 Command View AE Software.
• External Storage Software is installed on the target storage system.
• The external storage system is connected to one or more external ports of the internal storage
system.
In addition, determine:
• The required number and capacity of volumes you are virtualizing.
• The number of paths between the external and internal storage systems.

Virtualizing storage capacity
This module describes how to virtualize storage capacity.
About virtualizing storage capacity by creating THP pools
HP StorageWorks P9000 Thin Provisioning Software (THP) provides virtual volumes to a host and
allocates the actual capacity from a storage pool when a host makes a write request. By using Thin
Provisioning Software, you can allocate more capacity to a host than that allowed by the actual
physical configuration of the storage system.
Thin Provisioning Software provides the following advantages:
• You can reduce system setup and operational costs.
• You can use resources more efficiently.
• You can distribute workload equally among volumes.
HP StorageWorks P9000 Smart Tiers Software (Smart) improves the Thin Provisioning Software storage
performance. If you create a pool that combines volumes with different cost performance, such as
combining higher cost, high-speed volumes (SSD or SAS) with inexpensive low-speed volumes (SATA),
Smart Tiers Software rearranges the volume load automatically. This rearrangement is performed
depending on the I/O load; high-load pages are allocated to high-speed volumes, and low-load
pages are allocated to low-speed volumes.
You can create virtual volumes (THP) from physical volumes that are grouped into a THP pool. You
can then allocate those virtual volumes to hosts.
The volumes used to create a THP pool are called THP pool volumes.
P9000 Command View AE Software automatically selects volumes, and then creates a THP pool
according to the conditions you specify:
• Thresholds for consumed capacity or virtualization
Setting up and operating a SAN environment26
• Options for rearranging volumes
You must specify the following items when you create a Smart Tiers Software tier.
For HP StorageWorks P9500 Disk Array:
• Drive type (hardware tier). You can specify up to three types.
• Parity groups for each drive type.
In addition, you can specify volumes to create a THP pool. After you create a pool, you can create
THP volumes from the pool, or allocate a THP volume to a host by specifying a THP pool.
Naming a THP pool allows you to search, filter, and sort on pool names, which makes tasks, such as
allocating and creating volumes, easier.After you create a THP pool, you can check the pool information
to determine if you need to add capacity or migrate volumes. A pool for Thin Provisioning Software
that is in use can be expanded into a multi-tier configuration by changing it to a pool for Smart Tiers
Software.
If a THP pool includes zero pages, usability is poor. You can reclaim zero pages periodically and
when performing a backup or restoring data from tape storage.
Prerequisites for creating THP pools
Before creating THP pools, you must register the target storage system and verify these items, depending
on the storage system.
When using XP24000/20000 and HP StorageWorks P9500 Disk Array for THP pools:

Allocating volumes
This module describes how to allocate (provision), unallocate, delete, and create volumes, and manage
paths.
About allocating volumes
You must allocate volumes to a host so the host system can recognize them. The settings you assign
for allocating the first volume to a host become the default settings for the next time you allocate
volumes to the same host.
When you allocate volumes to a host, P9000 Command View AE Software assigns the paths between
volumes and the host.
If the volumes cannot be allocated with the specified settings, new volumes are created from unused
capacity, and then allocated to the host.
In a cluster environment, volumes can be allocated to multiple hosts at the same time.
Prerequisites for allocating volumes to hosts
Before allocating volumes to a host, verify that the host and storage systems are registered in P9000
Command View AE Software, and that appropriate permissions are set for all resources.
If you want to select volumes from a tier, an HP StorageWorks P9000 Tiered Storage Manager
software license must be enabled.
In addition, determine:
• The target host name
• The number and size of the volumes you are allocating
• An appropriate storage system
Allocating volumes to hosts
Before you allocate volumes to a host, review “Prerequisites for allocating volumes to hosts
” on page 30.
To allocate volumes to a host:
1. From the Resources menu, select Hosts.
2. Expand the tree and select the desired operating system.
