SC27-3655-01

EZD1172E
tcpstackname DETERMINED THAT ALL PARTNERS WERE UNREACHABLE FOR AT LEAST timevalue SECONDS

Explanation

Sysplex problem detection determined that there are no routes available to any partners.

tcpstackname is the name of the TCP/IP stack.

timevalue is the number of seconds that connectivity was not available.

System action

TCP/IP continues.
  • If the GLOBALCONFIG SYSPLEXMONITOR RECOVERY option is active and this stack is not the only member of its TCP/IP sysplex group, the following RECOVERY actions will occur:
    • This stack will leave the TCP/IP sysplex group.
    • This stack will no longer participate in sysplex distribution (as a distributor or target) or act as an owner or a backup for DVIPAs. All DVIPAs defined on this stack will be deactivated; however, the DVIPA definitions will be saved.
    • If the problem is corrected, this operator message will be deleted; if the GLOBALCONFIG SYSPLEXMONITOR AUTOREJOIN option is active, the stack will process the DVIPA definitions and rejoin the TCP/IP sysplex group.
  • If the GLOBALCONFIG SYSPLEXMONITOR NORECOVERY option is active, no action will be taken. If the problem is corrected, this operator message will be deleted.

See the information about sysplex problem detection and recovery in z/OS Communications Server: IP Configuration Guide for more information.

See the information about the GLOBALCONFIG statement in z/OS Communications Server: IP Configuration Reference for the definition of the SYSPLEXMONITOR parameters.

Operator response

Contact the system programmer.

System programmer response

Issue Netstat ROUTe/-r to determine which interfaces are used by the VIPAROUTE statements. Issue the Netstat DEvlinks/-d command to show which interfaces are active; check the system log for any messages related to the status of interfaces. If you cannot determine why the routes were lost, see the information about diagnosing OMPROUTE problems in z/OS Communications Server: IP Diagnosis Guide for additional information.

If this problem can be corrected, this operator message will be deleted.

If RECOVERY and NOAUTOREJOIN are active, then issue the VARY TCPIP,,SYSPLEX,JOINGROUP command to cause the DVIPA definitions to be processed, and the stack to rejoin the TCP/IP sysplex group.

If RECOVERY and AUTOREJOIN are active, no futher actions are needed. The stack will process the DVIPA definitions and rejoin the TCP/IP sysplex group.

If NORECOVERY is active, no further actions are needed.

After connectivity is reestablished, if RECOVERY is active, wait until message EZD1172E is issued when the process of leaving the sysplex group completes successfully. Then issue the VARY TCPIP,, SYSPLEX,JOINGROUP command to cause the stack to rejoin the sysplex group. If NORECOVERY is active, no further actions are needed.
