Monitoring SMS storage groups space

This topic describes the workspaces that monitor the status of SMS Storage Groups Space. You access these workspaces through the SMS Storage Groups Space node in the Tivoli® Enterprise Portal.

See the Monitoring the performance of user DASD groups section for information on how to add, edit, and delete a user DASD volume group.

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 Accessing workspaces to learn about navigating among workspaces. And see Integration with other products 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 SMS Storage Group report level. To access these commands, open the SMS Storage 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.

For a description of the attributes used as column headings in the workspace table view, review the attribute group definitions for this workspace in the online help. The help resource includes attribute descriptions that are displayed when you hover with the mouse pointer over a column heading.
SMS storage groups space table view
The table view contains one row of data for each SMS storage group. The view contains the following information:
  • The group name
  • The storage group status
  • The type and whether or not it is enabled
  • The number of volumes in the group
  • The status of the VTOC index
  • The lowest freespace percent of all volumes in the group
  • The highest fragmentation index of all volumes
  • The largest free extent
  • The total free space and the percent of free space for the group
  • The total amount of space for the entire storage group
Storage groups with free space % < 10 bar graph
This graph contains one bar for each storage group with a combined free space percentage that falls below 10%.
