2787939 - NIEHOST_UNKNOWN error when trying to start SAP

Symptom

The sapstartsrv process for the affected instance is running.

When issuing the start command, SAP does not start. The following error is observed:

hostname:SIDadm 100> sapcontrol -nr XX -function Start

<date and time>
Start
FAIL: NIEHOST_UNKNOWN, NiRawConnect failed in plugin_fopen()

-> "XX" is the instance number

When adding the "-debug" argument, the root cause is revealed:

hostname:SIDadm 101> sapcontrol -nr XX -debug -function Start
