Now restart elink trace.
# ./elinktrace -on -cfg /opt/OV/ovnm/bin/elink.cfg
Generate a Test message using the Test Message application for the NonStop node with problems. Test
message can be executed from either HPOM Java Console or “opc”.
From the HPOM Java Console:
•
Locate the NonStop Node name under Nodes and right-click on it.
•
Select Start>NonStop Tools>NonStop Operator Tools>Test Message.
From opc:
Drag the NonStop Node Icon (in the OVO Node Bank) to Test Message (in Application Bank –Nonstop
Tools-NonStop Operator Tools).
If no message is traced, check the NonStop EMS Log $0. If Test message are in the EMS Log, then the problem is
with the OVNM components on the NonStop Server.
If message are seen in Elink trace but are still not seen on HPOM Console, try tracing the OVNM Smart Plug In
process.
OSPI Tracing (OVNM Smart Plug In)
If problems still exist and there were no noticeable errors in the Elink log, you can verify whether the Events
messages are being received by the OVNM SPI (OSPI) process.
To enable OVNM SPI Tracing, stop the OVNM Agents on the HPOM UNIX Management Server and run the
ovnm_start_trace.sh
script.
#cd /opt/OV/ovnm/bin
#ovnm_start_trace.sh
Generate a Test message using the Test Message application for the NonStop node having problems. Refer to the
procedure for Elink Tracing.
The trace data can be viewed in /opt/OV/OVNM/bin/spi.log.
If messages are received in trace file but nor seen in the HPOM console then check to see if policies “SPI For
Nonstop Server” are installed and deployed on the UNIX HPOM Management Server.
After testing is complete, you can turn tracing off by stopping and restarting OVNM agents on the HPOM UNIX
Management Server using the following commands.
#ovnm_stop.sh
#ovnm_start.sh
