This workspace is the principal workspace for this node, and it enables you to monitor both types of virtual tape subsystems, 3494 and 7700.
In a table view, when you right-click the row for a 3494 subsystem, you see standard (non-7700) options. When you select a 7700 subsystem, you see only the link to the TS7700 Series Cluster Workspace.
When you click the Virtual Tape Subsystems node in the Navigator of the Tivoli Enterprise Portal, you see the Virtual Tape Subsystems workspace. The main components of the workspace are as follows:
-
Views
-
This workspace provides the following views. 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.

Virtual tape subsystems table view
-
The table view contains one row of data for virtual tape subsystem. The view contains the following information:
- The VTS name and library type
- The number of physical drives available
- The number of virtual devices online
- The average and maximum virtual mount pending times
- The virtual disconnect time
- The volume data (in gigabytes) read and written through the host channels to virtual volumes associated with this VTS
- The recall percent
- Number of scratch volumes, library type, model and serial number for this VTS
-
Volume recall % > 20 bar graph
-
This graph contains one bar for each VTS for which the percentage of virtual mounts to actual physical mounts exceeds 20%. The bar height indicates the recall percentage.
-
Average virtual mount pending time > 300 bar graph
-
This graph contains one bar for each VTS for which the average time spent waiting for a virtual mount exceeded 300 seconds. The height of the bar indicates the actual time spent waiting.
-
TS7700 Worst Statistics table view
-
The table view contains one row of data for each TS7700 Node/Cluster. The view contains the following information:

- The hexidecimal field indicates the cluster ID.
- The node's machine type.
- The node's model type.
- The serial number of this node.

- The maximum total number of gigabytes (read + write) processed by the z/OS host channels to the virtual tape volumes associated with this cluster of the selected TS7700 grid for the last 24 hours.
- The maximum percentage of the virtual mounts that result in a physical mount in this cluster of the selected TS7700 grid for the last 24 hours.
- The minimum number of empty physical cartridges for use in this cluster of the selected TS700 grid for the last 24 hours.
- The Name of this TS7700 Cluster.
- Cluster ID and Machine Serial Number.
- The maximum size of the Cluster's TVC in increments of GB (1024x1024x1000) for the last 24 hours.

- The maximum number of scratch mounts for the last 24 hours.
- The maximum megabytes Read by the Channel for the last 24 hours.
- The maximum gigabytes Read by the Channel for the last 24 hours.
- The maximum megabytes Written by the Channel for the last 24 hours.
- The maximum gigabytes Written by the Channel for the last 24 hours.
- The maximum sum of MB Read and MB Written for the last 24 hours.
- The maximum sum of GB Read and GB Written for the last 24 hours.
- The maximum percentage of 30-second periods where there was at least one throttling value greater than zero and that write overrun was the predominant reason for that throttling for the last 24 hours.
- The maximum average throttle value during the interval for the last 24 hours.
- The maximum percentage of 30-second periods where there was at least one throttling value greater than zero and that copy was the predominant reason for the throttling for the last 24 hours.
- The maximum average copy throttle value during the interval for the last 24 hours.
