Overview of HP StorageWorks XP Provisioning Manager 20
Figure 1-5 Using Provisioning Manager to Manipulate Storage Subsystems
The following explains the flow of operations on subsystems that use Provisioning Manager:
1. Install the storage subsystems and hosts. Use Device Manager to install. Installing storage subsystems
by using Device Manager allows you to use Provisioning Manager to manage all the LDEVs and LUs
defined in the storage subsystems. Also, installing the Device Manager agent on the installed host allows
you to use Provisioning Manager to manage the file systems and device files on the host.
2. Allocate the LDEVs to user groups created for each purpose so that you can manage storage pools by
usage, such as by database or business application. Use Device Manager to define user groups and the
access scope for the volumes. Provisioning Manager recognizes the volume access scope defined in this
manner as a storage pool that is a collection of volumes for each user group.
3. Use Provisioning Manager to manage volumes used by databases and business applications. First,
allocate a volume in a storage pool to a host on which the database or business application is running.
Then, assign each host volume as a file system or device file for databases or business applications.
Performing the above configuration enables databases or business applications to use the storage
subsystems.
4. If you wish to detach an allocated volume when you have decided to stop a database or business
application that is no longer needed, you can use Provisioning Manager to remove the file system or
device file.
5. To remove a host that is no longer needed, use Provisioning Manager to detach the volume from the host
to which it is allocated. Once you have confirmed that the volume is no longer allocated to the host you
wish to remove, you can safely remove the host from the SAN. After you have removed it, use Device
