Steps for dynamically adding an IBM 10GbE RoCE Express interface

Use these steps to dynamically add an IBM® 10GbE RoCE Express® interface.

Procedure

Perform the following steps:

  1. Install and configure the 10GbE RoCE Express feature in the hardware configuration definition (HCD). Configuration includes the physical network ID (PNet ID) for the 10GbE RoCE Express port. For more information, see Physical network considerations.
  2. Add the new PCI Express function ID (PFID) to the GLOBALCONFIG SMCR parameter in the TCP/IP profile data set.
    Rule: In addition to the PFID that you are adding, you must also specify all currently configured PFIDs on the GLOBALCONFIG SMCR parameter. When you update the configured PFIDs on the GLOBALCONFIG SMCR parameter, you are completely replacing the configured PFID information.
  3. Issue the VARY TCPIP,,OBEYFILE command and specify the updated TCP/IP profile data set.

Results

If any SMC-R capable IPAQENET and IPAQENET6 interfaces were ever active, the 10GbE RoCE Express interface that the added PFID represents is automatically started. Otherwise, the interface is started when the first SMC-R capable interface is started.

What to do next

For more information about dynamically updating the GLOBALCONFIG SMCR parameter, see z/OS Communications Server: IP Configuration Reference.
