Create a Sysplex or Monoplex

A sysplex is a system complex which is a single logic system running on one or more physical systems. Each of the physical systems that make up a sysplex, is often referred to as a member system. A monoplex is a sysplex that has only one member system and minimally a single coupling facility.

You can use sysplex and monoplex systems as target systems for product configurations.

If you have monoplexes with the same sysplex name, you can create a sysplex or monoplex system registry. Monoplexes are stored in the sysplex registry tree but with the name of the sysplex system and not the monoplex sysplex name. For example, you have a system XX16 defined as a monoplex, with a sysplex name of LOCAL. The system registry displays the system as a sysplex, with the name LOCAL. This sysplex contains one system: XX16.

Note: If you create a system in the wrong group, it is determined during validation and the system is moved to the right group automatically. For example, if you add a monoplex to a non-sysplex category, a new sysplex group is created. The monoplex is moved to that sysplex group.

Follow these steps:

  1. Click the System Registry tab, and in the Actions section click the Create Sysplex link.

    The New Sysplex dialog appears.

  2. Enter the following information, and click Save.
    Name

    Enter the sysplex system name.

    Limits: Eight characters

    Description

    Enter the description.

    Limits: 255 characters

    Sysplex and non-sysplex system can have the same name. Use the Description field to differentiate these systems.

    The sysplex system is saved, and its name appears in the sysplex list on the right.

    Important! z/OS systems running under VM are treated as being in BASIC mode and not LPAR mode. As a result, the LPAR number is null in the z/OS control block. In this case, the system validation output includes the following message:

    Property Name: z/OS LPAR Name, Value: ** Not Applicable **.
  3. Right-click the newly added sysplex and select Create Sysplex System to add a system to a sysplex. Repeat this process for each system belonging to this sysplex.
  4. Enter the following data items for each system:
    Name

    Enter the system name.

    Limits: Eight characters

    Note: Sysplex and non-sysplex systems can have the same name. Use the Description field to differentiate between these systems.

    Description

    Enter the description.

    Limits: 255 characters

    CAICCI System ID

    (Optional) Enter the CAICCI system ID.

    Limits: Eight characters

    Note: The CAICCI system ID is a unique name for a system that is part of a CAICCI network. If you do not specify one, CA CSM obtains it using a validate action.

    The sysplex system is saved, and its name appears in the sysplex system list on the left.

  5. Detail the nonstaging system.
