Open and close a sysplex

An open sysplex is characterized by the indicator [+] in front of its name. This indicator can be used to expand the sysplex.

Without this indicator, the sysplex is closed and needs to be opened to access its resources. To open a sysplex either double click on it, or select Open from its context menu. Then, the Sysplex Logon dialog will pop up.

To close a sysplex, select Close from its context menu. All contained resources will not be accessible until the sysplex is opened again.

You can also use the path File - Open/Close - Sysplex... to open or close a sysplex. This leads you to the Sysplex Selection dialog where you have to specify the name of the sysplex.
