Controls the display of IST663I, IST664I, and IST889I messages when an APPN locate search fails to find the destination LU. The ESIRFMSG and FSIRFMSG start options can be used in conjunction with LSIRFMSG to generate additional messages as part of this message group.
  • ESIRFMSG controls whether IST891I, IST892I, and IST893I are displayed.
  • FSIRFMSG controls whether the IST1942I, IST1943I, IST1944I, IST1945I, IST1946I, IST1947I, IST1948I, IST1949I, IST1950I, IST1951I, IST1952I, IST1953I, IST2208I, and IST2209I messages are displayed.

LSIRFMSG is meaningful only if the NODETYPE=NN start option is also used.

You can change the value of LSIRFMSG with the MODIFY VTAMOPTS command while VTAM® is running.
LSIRFMSG=ALLNNS
Specifies that APPN locate search failure messages are always to be issued by this network node regardless of node role.
LSIRFMSG=OLUNNS
Specifies that APPN locate search failure messages are to be issued by this network node, only when acting as the network node server of the OLU or when acting as the origin directory server of the search.
LSIRFMSG=NONE
Specifies that APPN locate search failure messages are not to be issued by this network node.

Guideline: Because of the volume of messages that can be generated, it is not recommended that this option be enabled during normal operation. Instead, it is recommended that this option be enabled (using the MODIFY VTAMOPTS command) on all necessary hosts only when trying to diagnose specific problems. Once the problem has been diagnosed or documentation has been collected, this option should be disabled once again (using the MODIFY VTAMOPTS command).

Tip: When ESIRFMSG or FSIRFMSG start options are used in conjunction with LSIRFMSG, then ALLSSCP is equivalent in function to ALLNNS and OLUSSCP is equivalent in function to OLUNNS.
