Sysplex Management
This chapter provides a description of and usage information about IBM z/OS Management Facility (z/OSMF) Sysplex Management. It includes the following topics:
15.1 Introduction
The Sysplex Management task allows you to view sysplex resources.You can view sysplexes and systems in a sysplex. You also can view physical configurations, such as coupling facilities and LPARs, and logical resources, such as couple data sets and coupling facility structures.
Graphical views help you to visualize the topology of your sysplex. From the graphical view, you can drill down for more information.
Many of the pages in the Sysplex Management task include a graphic view and a table view. You can drag the divider that separates the views to expand or reduce each section.
The graphic view is in the upper portion of the window. Sysplex objects, such as CPCs and coupling facilities, are shown in graphic form. Right-click a link inside an object (typically the name of the object) to display a menu of actions that are available for the object.
15.2 Prerequisites
To define systems with the Systems task in the z/OSMF Settings, complete the following steps:
1. Add a z/OSMF instance for each sysplex to manage by current z/OSMF instance.
2. Enable single-sign (SSO) for each secondary z/OSMF instance by using the Enable Single Sign-on action in the Systems table.
3. To prepare for the use of the physical view for the local sysplex, use the Discover action in the Systems table to automatically create system definitions for those systems, or use the Add CPC action to manually add all CPC information for the local z/OSMF instance, as described in 3.16, “Sysplex” on page 61.
15.3 Usage
First, we expand the Sysplex category in the navigation area. Then, we select Sysplex Management, as shown in Figure 15-1.
Figure 15-1 Sysplex Management plug-in
The topology of the defined sysplex in a graphic and a table view is shown in the first window (see Figure 15-2). From the main page, you can see a more detailed view of the sysplex definitions.

Use the Zoom Level option to zoom in on or out of the graphic. From a drop-down list, you can select a predefined zoom level. This value can also be overwritten with your own zoom level, as shown in Figure 15-3.
Figure 15-3 Choosing a Zoom Level
Use the Highlighter feature to define colors for the objects that are displayed in that view. An example of changing the color of the sysplex is shown in Figure 15-4. You can reset all of your changes immediately by clicking Restore Defaults.
Figure 15-4 Change Highlighter of Graphic View
Use the Export feature to save the graphic view as a scalable vector graphics (.svg) file. Icons in the graphic view typically appear before an object to indicate its type (such as the CF icon for coupling facility), which are not included in the .svg file. The exported .svg file might not be well-formatted if the length of the text is too long.
An example of the Export function is shown in Figure 15-5.

Right-click the sysplex name (as shown in Figure 15-6) to open a selection of other views.
Figure 15-6 Options for View
Click View Properties to see a more detailed view, as shown in Figure 15-7.
Figure 15-7 Displaying the detail view
The fields that are available in the detailed view are listed in Table 15-1.

Field
|
Description
|
|
Sysplex Name
|
Name of the Sysplex.
|
|
Initialization time
|
Date and time that the sysplex was initialized.
|
|
Active Policies
|
Table that lists the active policies, including the name, type, and date and time that they were activated.
|
|
Couple Data Sets
|
Table that lists the couple data sets, including the name, type, usage, and volume serial.
|
|
Systems
|
Table that lists the systems in the sysplex.
|
|
Coupling Facilities
|
Table that lists the coupling facilities in the sysplex, including the name, partition, and CPC.
|
To see more information about the couple data sets, we click the SYS1.XCF.CDS02 link in our example. The properties of the Sysplex couple data set (CDS) is shown in Figure 15-8. You can click every CDS to see more information.

Return to the main page and select Open to see a physical view of the sysplex. As shown in Figure 15-9, the physical view of this sysplex is presented in a graphic view. The couple data set information also is shown in this graphical view.
Figure 15-9 Physical View of Sysplex upper part
Below the graphic view you can see the table view. By default, you see the CDS information. You can select between CDS and CPC information. An example of the CDS view is shown in Figure 15-10. The view easily can be changed by using a drop-down menu.
Figure 15-10 Table View Couple Data Sets of Sysplex
The physical view can be changed to see more information about the coupling facility (CF). You can change the View in the upper right corner, as shown in Figure 15-11.
Figure 15-11 Graphic View options
The CF Connectivity Details view of the sysplex are shown in Figure 15-12. In the table at the bottom of the window, you see more information about the CF connections, such as CHPID, Adapter, Port, Type, and CF Name.
