Direct situation analysis for the SMS Storage Groups Space workspace

The SMS Storage Groups Space workspace produces situation event workspaces when the following situations resolve to true:

You can navigate from one of these situation event workspaces directly to the following workspaces to do direct situation analysis:

Table 1. Situation: KS3_Storage_Gr_Pct_Free_Critical/Warning
Workspace for direct situation analysis Comments

Storage Group Percent Free

Default navigation is to this workspace. These are new situations that provide alerts when the percentage of free space in a storage group falls below specified thresholds. They alert the user when there is a danger of allocation failure due to a lack of storage in the group.

The rows in the report and entries in the bar charts are sorted in ascending order by Percent Free Space. This workspace derives its data from the DASD Volume Space attribute table.

Use this workspace to determine which volumes in the group have the least amount of available space. The report lists all volumes in the group. The 'Volume Free Space' chart immediately identifies those volumes with a low amount of available space. The 'Fragmentation' chart immediately identifies the volumes in the group that are fragmented.

Storage Group Percent Free Trend

This workspace derives its data from the Volume Group Summary attribute table.

Use this workspace to determine if the lack of free space is a spike or a trend. If it's a spike then migrating data might resolve the issue; however, if it's a trend then it might be time to add a volume or more to the group. The report shows complete space data for the group. The plot chart enables the user to immediately determine if the lack of available space is a trend or a spike.

Dataset Space Event

Default navigation is to this workspace. Navigation to the new 'Volume Space Trend' workspace is also available from the existing 'SMS Storage Group Volume Space' and 'User DASD Group Volume Space' workspaces.

This workspace includes the Tracks Unused attribute from the Dataset Space attribute group. The rows in the report are sorted in descending order by Tracks Unused. This workspace derives its data from the Dataset Space attribute table (report) and the DASD Volume Space attribute table (pie chart).

Use this workspace to determine what data sets on the volume have the most unused space allocated. The chart displays the available space on the volume.

Volume Space Trend

The plot chart plots the volume Percent Free Space attribute. The report consists of the following attributes from the DASD Volume Space attribute table:
  • Total Capacity Megabytes
  • Free Space Megabytes
  • Percent Free Space
  • Fragmentation Index
  • Largest Free Extent MB
  • VTOC Index Status
  • SMS Status
This workspace derives its data from the DASD Volume Space attribute table.

Use this workspace to determine if the shortage of available space is a spike or a trend. The action taken to correct this problem differs depending on that information. The report provides complete space information for the volume. The plot chart displays the free space percent over time.
