HP XP Array Manager Software - Manual (Page 34)

A Tiered Storage Manager license is required to perform the operation from the Mobility tab. To edit
a tiering policy:
1. From the tree view in the Resources tab, select Storage Systems.
2. Expand the tree and select the target Smart Tiers Software pool.
3. If you chose Smart Tiers Software pool, select one or more THP volumes from the THP Vol tab
and then click the Edit Tiering Policy button.
4. Select the hardware tier for the tiering policy, and then execute the task.
5. View the list of tasks to make sure that all tasks are complete. You can schedule the task to be
executed later.
Allocating and unallocating volumes
This module describes how to allocate (provision) 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 Suite assigns the paths between
volumes and the host.
If the volumes which match the specified volume requirements do not exist, 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. Volumes can
be allocated to storage ports for which LUN security is disabled only when connected via Fibre
Channel.
If you want to add capacity to a host for which volumes have been allocated, you can allocate volumes
using the existing settings of volumes already allocated (such as the target host, capacity, volume
type, drive type, path configuration, and logical group).
Allocate Volumes dialog box
This section describe the fields and use cases for the Allocate Volumes dialog box in P9000 Command
View AE Suite.
Storage can be allocated from many different points in Device Manager depending on specific system
parameters (host, volume, performance levels, etc.). Several of the most common approaches to
allocating volumes and provides lists of common GUI fields are described below.
The most common allocation methods are:
• Allocating volumes to a specific host:
You can select one or more hosts and then allocate volumes to them.
• Allocating specific volumes to a host:
In this use case you want to select a specific volume to allocate to a specific host
• Allocating volumes to a host cluster:
In this use case you allocate a volume to a host cluster by creating a logical goup. Device Manager
does not have host clustering information and so requires a logical group as the bridge between
