4 Grouping resources
This module describes how to group logical groups and storage tiers (resources).
Managing logical groups
This module describes how to manage the two supported logical group types: public and private.
Public and private logical groups are listed in the navigation pane (Resources > Logical Groups) under
the Public Logical Groups root folder and the Private Logical Groups root folder, respectively.
About logical groups
A logical group is a mechanism for the grouping of storage resources (hosts and volumes) by storage
administrators, and can be organized according to business operations, geographic locations, or
other organizational divisions.
Using grouped storage resources as logical groups allows you to:
• Create summary reports that indicate current resource use in a storage environment by organization.
You can create logical groups that generate usage summary reports for each organization that
uses storage, if you manage an entire system.
• Monitor volumes and perform storage system operations by grouping together managed resources
(hosts and volumes).
You can categorize volumes according to the organizations that use the storage, if you manage
a part of a system. Grouping and categorizing volumes makes finding volumes easier and allows
you to perform daily operations for volume resources.
You can add multiple hosts or volumes to a logical group at one time by specifying a range of IP
addresses, or by specifying multiple items, such as operating system type and drive type. The same
hosts or volumes can be registered to multiple logical groups.
When you need to, you can add or remove hosts and volumes from a logical group, or change the
hierarchy, or structure, of existing logical group folders, depending on the logical group type. Any
volumes allocated to a host in a logical group are automatically assigned to the logical group.
HP StorageWorks P9000 Command View Advanced Edition Suite software supports two types of
logical groups: public and private. A key distinction between public and private logical groups is the
root location in the work area for the user, and these two logical group types have the following basic
structure in the navigation pane:
Public logical groups
• Logical group folders that contains groups of hosts and volumes that are grouped by business
function, geographic, or other organizational divisions.
• Logical groups of hosts.
• Logical groups of volumes.
Private logical groups
