FAIL: NIECONN_REFUSED (Connection refused), NiRawConnect failed in plugin_fopen()

 

Environment

SUSE Linux Enterprise Server for SAP Applications
SUSE Linux Enterprise Server 12

Situation

In the logs there are entries like

018-06-28T03:45:42.719624+02:00 unsinkable_02 lrmd[40931]:   notice: rsc_SAPHana_HAL_HDB00_monitor_61000:211324:stderr [ Error: NIECONN_REFUSED (Connection refused), NiRawConnect failed in plugin_fopen() ]

and the SAP Instance cannot be operated by the Cluster for example.

This can affect normal SAP Instances like ASCS/ERS as well as HANA.

Resolution

Most likely reason for this is that the sapstart service is not running, it can be checked via

   unsinkable_02:~ # /bin/systemctl --no-pager --all list-units | grep sapinit

     sapinit.service        loaded    active   running   LSB: Start the sapstartsrv

or


     sapinit.service        loaded    active   exited   LSB: Start the sapstartsrv

and in case this returns something like

   sapinit.service       loaded    inactive dead      LSB: Start the sapstartsrv

   sapinit.service          loaded    failed   failed    LSB: Start the sapstartsrv

this can be fixed with

   unsinkable_02:~ # /bin/systemctl restart sapinit.service

Cause

The process sapstartsrv which is used for operating the SAP Instances was either killed, stopped or otherwise not available
