Reconfiguring the system in response to a configuration display

Use the following form of the CONFIG command before making any changes to the system configuration, or to display the processors, Integrated Cryptographic Features (ICRFs) attached to the processors, total amount of storage, channel paths available to the system, PCIE function identifiers (PFIDs) available, and the online or offline status of each channel path. (To obtain more information on storage, use the DISPLAY M command.)

In response to this command, the system issues messages IEE521I and IEE522D. Message IEE521I displays the reconfigurable resources available to the system, including processors, ICRFs attached to the processors, total amount of central storage, central storage elements, PCIE function identifiers (PFIDs), and channel paths. If your processor complex is partitioned, message IEE521I contains this information for one side. Respond to message IEE522D with the processors, total amount of central storage, PCIE function identifiers (PFIDs), as well as channel paths you want to bring online or take offline.

If the system is unable to display the resources available to the system, message IEE521I indicates that the command was unsuccessful.

 
CF {ONLINE|ON  }[,L={a|name|name-a}]
   {OFFLINE|OFF}

ONLINE or ON: The system is to display the system configuration so that you can decide which processors, ICRFs attached to the processors, central storage elements, PCIE function identifiers (PFIDs), and channel paths you want to bring online. The system brings online the processors, ICRFs attached to the processors, storage elements, PCIE function identifiers (PFIDs), and channel paths you specify in response to message IEE522D. If an ICRF is attached to a processor that is being brought online and the Integrated Cryptographic Service Facility/MVS (ICSF/MVS) is active, the system brings the ICRF online.
OFFLINE or OFF: The system is to display the system configuration so that you can decide which processors, ICRFs attached to the processors, central storage elements, PCIE function identifiers (PFIDs), and channel paths you want to take offline. The system takes offline the processors, ICRFs attached to the processors, storage elements, PCIE function identifiers (PFIDs), and channel paths you specify in response to message IEE522D. If an ICRF is attached to a processor that is being taken offline and the ICSF/MVS is active, the system takes the ICRF offline.
L=a, name or name-a: The display area where the system is to display the system configuration. You can specify the display area (a), console name (name), or both (name-a). If you do not specify this option, the system displays the system configuration in the first available display or message area of the console on which you entered the command.

Example 1:

To check the channel paths available to the system before bringing any online, enter:

cf online

When message IEE522D appears after the configuration display message, IEE521I, reply with the channel paths you want to bring online.

Example 2:

To check the available processors, central storage elements, PCIE function identifiers (PFIDs), and channel paths in the system and the online or offline status of each, enter:

cf offline     or     cf online

When message IEE522D appears after the configuration display message IEE521I, reply with NONE.
