Shared DASD Groups Data for Sysplex workspace

The Shared DASD Groups Data for Sysplex workspace displays information to help identify the devices and datasets responsible for significant I/O time or delays for important workloads. Use the information to determine how equitably a device is serving all systems in the sysplex. Select a DASD group in the table view to display details for that particular group of DASD devices.

Note: The group name is the system managed storage (SMS) managed group name.

The Shared DASD Groups table provides statistics on device contention and percentage busy for all the groups in the sysplex. The Group True Busy bar chart graphically displays the average and highest true busy percentages for all groups, and the Group Contention Index chart shows the average and highest device contention indices for each group.

From the Shared DASD Groups table, you can link to a workspace displaying statistics for the individual devices in a selected group.

Note:
No data is displayed in this workspace unless a DASD filter situation is enabled.
