Symptom
SAP HANA system does not start up. In the database traces you can find messages similar to the following:
[96593]{-1}[-1/-1] 2020-05-28 10:44:00.562460 w Basis ChannelListener.cpp(00101) : Unable to create socket for name: ...
[96593]{-1}[-1/-1] 2020-05-28 10:44:00.562461 w Basis ChannelListener.cpp(00101) : Application for this process will only work with 'hdbcons -p <pid>'
[96593]{-1}[-1/-1] 2020-05-28 10:44:00.568711 f self_watchdog SelfWatchdog.cpp(00277) : An instance of this service is already running.
You should consider checking if the process with the id <pid> is running
and of type hdbnameserver. If you are sure that there is no instance alive
remove the file /usr/sap/<SID>/HDB<PORT>/<hostname>/lock/hdbnameserver@30001.pid
and restart.
[96593]{-1}[-1/-1] 2020-05-28 10:44:00.568732 f Service TrexService.cpp(00620) : could not create lock file: 'hdbnameserver : 30001'
This issue may happen also on different services also such as indexserver, as shown below:
[4017]{-1}[-1/-1] 2017-06-01 02:33:31.045520 f Service TrexService.cpp(00656) : could not create lock file: 'hdbindexserver : 30003'
