DVIPA target removed record (subtype 35)

The dynamic virtual IP address (DVIPA) target removed record is created by a sysplex distributor stack when an active target stack is removed from distribution.

Creation of this SMF record is controlled by the following parameters and options:

  • DVIPA and NODVIPA parameters on the SMFCONFIG profile statement

    If DVIPA is specified, the record is created and written to the SMF MVS™ data sets.

  • DVIPA and NODVIPA options of the SMFSERVICE parameter on the NETMONITOR profile statement

    If DVIPA is specified, the record is created and written to the real-time TCP/IP network monitoring NMI. For more information about this NMI, see Real-time TCP/IP network monitoring NMI.

See Table 1 for the contents of the TCP/IP stack identification section. For the DVIPA target removed record, the TCP/IP stack identification section indicates STACK as the subcomponent and X'08' (event record) as the record reason.

Table 2. DVIPA target removed section
Offset Name Length Type Description
0(X'0') SMF119DV_TRIPAddr4 4 Binary If SMF119DV_TRFlags_IPv6 is not set, this field contains the IPv4 DVIPA address.
0(X'0') SMF119DV_TRIPAddr6 16 Binary If SMF119DV_TRFlags_IPv6 is set, this field contains the IPv6 DVIPA address.
16(X'10') SMF119DV_TRDxcfAddr4 4 Binary If SMF119DV_TRFlags_IPv6 is not set, this field contains the IPv4 dynamic XCF address of the target stack that was removed.
16(X'10') SMF119DV_TRDxcfAddr6 16 Binary If SMF119DV_TRFlags_IPv6 is set, this field contains the IPv6 dynamic XCF address of the target stack that was removed.
32(X'20') SMF119DV_TRFlags 1 Binary Various flags:
  • X'80', SMF119DV_TRFlags_IPv6: If set, DVIPA address and dynamic XCF address are IPv6.
  • X'40', SMF119DV_TRFlags_DestIPAll: If set, DESTIP ALL was specified on the VIPADISTRIBUTE DELETE statement.
  • X'20', SMF119DV_TRFlags_DynPorts: If set, dynamic ports were specified for this target.
33(X'21')   1 Binary Reserved
34(X'22') SMF119DV_TRPort 2 Binary The DVIPA distributed port number. If dynamic ports are in use for this DVIPA, this port number might be 0.
36(X'24')   12 Binary Reserved
