Virtualizing volumes
Before you perform this task, review “ Prerequisites for virtualizing volumes ” on page 25.
To virtualize volumes:
1. From the Actions menu, select Virtualize Volumes.
2. Specify the appropriate information.
To change default values, click Path Priority Setting, Host Group and LUN Settings, or External
Volume Configuration to specify new values.
3. Click Show Plan to review the plan and specify additional information, as appropriate:
• Verify the information that is displayed.
• Enter a name in Task Name.
• Specify when the task should run.
4. Click Submit.
The plan is registered as a task.
5. When the task completes, check the Storage Systems list to confirm that the external volumes are
mapped to the target storage system.
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:
