Switch IOCDS for processors in a System z cluster with SNA address defined

The following procedure describes how to build an IOCDS for processors in a System z cluster with an SNA address defined. For a detailed description of the following dialog sequence, refer to Build System z cluster IOCDSs.

1. On the Primary Task Selection panel, select Activate or process configuration data and from the resulting panel select Build and manage System z cluster IOCDSs, IPL attributes and dynamic I/O changes.. The System z Cluster List is displayed (see Figure 93).
2. On the System z Cluster List, select the CPCs for which you want to switch the IOCDSs and Work with IOCDSs from the context menu (or action code  s ). HCD displays the IOCDS List (see Figure 94).
3. Use the Switch IOCDS action (or action code  s ) to mark an IOCDS as the IOCDS that is used for next POR. The Status field will be set accordingly.

   You can only switch to an IOCDS that has an IOCDS/HSA token match or to an IOCDS of a processor that is not activated ('POR-required' status).
