This topic describes the workspaces that
report the status of user DASD groups space. This topic also describes
the dialog boxes that you use to add, edit, delete, and migrate a
user DASD volume group.
A user DASD group is a user-defined logical grouping
of DASD volumes. Volumes within a user DASD group are typically related
according to some criteria. You can define a user DASD group based
on volume name, device address, SMS storage group, or one or more
DASD volume attributes (for example, Fragmentation Index, Response
Time, and other attributes). After you define a user DASD group, you
can use the User DASD Group Performance and User DASD Group Space
workspaces to view aggregated performance and space metrics for the
group as a whole. From these two workspaces, you can drill down to
other workspaces that display performance and space metrics for each
volume in the group.
You dynamically allocate user DASD volume groups.
You access these workspaces through the User DASD Groups Space node
in the Tivoli® Enterprise
Portal.
See Workspaces for
general information on predefined workspaces and a list of all nodes
that are included in the OMEGAMON for
Storage on z/OS product.
Each node corresponds to a specific area of storage resource monitoring.
And each node includes links to a unique set of storage resource workspaces.
See Workspaces to learn about navigating
among workspaces. Also see Workspaces to
learn about linking to the workspaces of other IBM Tivoli Monitoring
products.
In addition, with OMEGAMON for
Storage on z/OS Version 4.2.0
Interim Feature 3 or later, you can issue volume-level Storage Toolkit
commands from the User DASD Group report level. To access these commands,
open the User DASD Groups Space workspace from the Navigator, right-click
a row on the table view and select the Volume Actions... menu
item, then select the action you want to perform.
Note: User groups defined within the Configuration Tool
are not visible in the
OMEGAMON for
Storage on z/OS product
unless they have been migrated. See
Migrating user DASD group definitions for more information
on how to migrate user DASD groups.
