Using Provisioning Manager 45

1. Use the Device Manager host registration function to manually register the host in a system (register the

WWN of the host port).

2. Use Device Manager to place the host under the management of the user group that manages the

storage pool.

3-2-2 Unallocating a Volume

You can select one or more allocated volumes from among those listed to unallocate them from a host.

When you unallocate a volume from a host, configure all the settings for the storage subsystem from the list of

allocated volumes displayed in Provisioning Manager.

3-3 Managing Hosts

You can use Provisioning Manager to manage hosts to which storage volumes have been allocated.

Provisioning Manager provides functions for displaying and updating (refreshing) host information.

3-3-1 Viewing Host Information

You can view the attributes of a selected host. Here, the term attributes refers to the information needed to

operate Provisioning Manager, such as information for recognizing the host, a summary of the volume

operation information, and information on prerequisite and related products that are installed. Examples of the

information displayed in a Show Hosts window are listed below.

• Host recognizing information: Name and IP address of a host

• Summary of volume operation information: Total capacity of storage utilized by a host

• Information on prerequisite and related products: Operating systems, Device Manager agents, path

management software, volume managers, and similar products

Note that information normally reported using Device Manager agents that are not installed, or Device Manager

agents that are installed but are not active, cannot be displayed or configured as host information.

3-3-2 Updating Host Information

Not only can Provisioning Manager be used to obtain host information from a Device Manager agent but, by

using the update (refresh) function, you can update all information displayed by Provisioning Manager

whenever needed. You can update host attributes, and you can also update detailed information on volume

operation, such as file system information and device file information.

The only times other than by using the refresh function that information can be obtained from a Device

Manager agent is when the Device Manager agent is started, when a HiScan command is executed, or when

the agent periodically reports. This means that, if a user is performing manual operations on a host, the

configuration results are not updated to Provisioning Manager at that time. Note, also, that reports obtained

from Device Manager agents in these latter cases do not update information from prerequisite and related

products. The information from prerequisite and related products is registered in Provisioning Manager by the

refresh function.

3-4 Creating, Expanding, and Deleting File Systems

Creating a file system on a volume (LU) allocated to a host, expanding a file system, and deleting a file system

can all be performed from a management client in a single operation.

3-4-1 Creating a File System

Once you specify a host and select a volume (LU) from among the volumes allocated to that host, Provisioning

Manager can automatically perform a series of operations to create a file system on that volume. The created

file system is mounted on the file system that is on the host’s OS.

To create a file system, specify the following:

• File system type: Select a file system type from among those that can be used by the host.

• Mount point: Specify the path name to indicate the location of the mount point for the file system. This

path name is used later to recognize the file system.

CAUTION: Double-byte code, such as a Japanese character, is not usable for the mount point name to

be specified when adding a file system.

• Volume manager: To use a volume manager, select one from among the volume managers that are

installed. You must specify a volume manager to create an expandable file system.
