Issue the Netstat VIPADCFG/-F command to determine which DVIPAs are configured on this stack.

If the VIPADISTRIBUTE statement was incorrect, change that statement in a VARY TCPIP,,OBEYFILE data set to specify the appropriate TIER parameter value. If the VIPADEFINE statement was incorrect, specify a VIPADELETE statement for the DVIPA in a data set that is referenced by a VARY TCPIP,,OBEYFILE command, followed by a VIPADEFINE statement for that DVIPA that specifies the appropriate TIER parameter. Also, to delete any existing VIPADISTRIBUTE DEFINE statements that reference this DVIPA, include the VIPADISTRIBUTE DELETE statements before the VIPADELETE statement in the data set.

See the information about the VIPADYNAMIC statement in z/OS Communications Server: IP Configuration Reference for more information about the VIPADISTRIBUTE profile statement.
