Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * All users of the IBM Communications Server for z/OS Version  *
  * 2 Releases 1 and 2:  Dynamic VIPA                            *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * New Function to enhance the return information on a failed   *
  * ioctl() request for SIOCSVIPA/6 to create a Dynamic VIPA     *
  * with affinity.  The -a option of the moddvipa utility can be *
  * used to create a Dynamic VIPA with affinity as an            *
  * alternative to programming the ioctl().                      *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The SIOCSVIPA/6 ioctl() processing does not distinguish between
  a retryable condition and a request that is invalid based on the
  current VIPADYNAMIC configuration.  If the TCPIP stack has not
  processed the VIPADYNAMIC configuration or has not joined or
  left the sysplex, the ioctl() request to create a Dynamic VIPA
  will fail with EINVAL and JrDVIPANotInVIPARange.  The requested
  Dynamic VIPA address may be defined correctly within the scope
  of a VIPARANGE definition after the VIPADYNAMIC configuration is
  processed.  It would be more appropriate under these
  circumstances to return a retryable error.
  

Problem conclusion

• The SIOCSVIPA/6 ioctl() create with affinity processing has been
  amended to return EAGAIN and JrDVIPAServicesNotActive when the
  TCPIP stack has not processed the VIPADYNAMIC configuration.
  This provides the information needed for programs issuing the
  ioctl() and users of the moddvipa utility with the -a option to
  identify a retryable condition.
