HP NonStop G-Series - Manual (Page 67)

Troubleshooting OVNM 67
• If both Elink Ports 5020 and 5030 are red then the Elink session between the Operations Manager
Management Server and the NonStop Host has failed. Stop and Start the OVNM Agents on the Operations
Manager Server using the Start Agents and Stop Agents options in the StartProgramsHP
OVNMManagement Server Tools menu.
Figure 7-7 Management Server Tools Menu
Check for the HP OVNM SPI Service either by using the ‘net start’ command or from the Services window.
There are 2 services:
• HP OVNM ELINK Service
• HP OVNM SPI Service
If NonStop Node status is still red , verify the OVNM NonStop Server components using the Host Management
Client as described above.
7-2-2 Elink Service Tracing in Windows (Communication Interface)
If problems still exist, you can view the Elink log file using Notepad.
By default the Elink Service logs ERROR to :\Program Files\OVNM\Elink\Elink.log.
Here is an example error message in the Elinks log file.
ERROR: Connection failed to host \NSKIT01:5030(getsockopt error=10061)
error 10061: Indicates that a socket error occurred when attempting to access the node \NSKIT01. This error
occurred because the OVNM NonStop Agent was not running on the node.
If required, the Elink tracing levels can be changed to view event messages without having to stop the Elink
Service. Changing the Tracing level can be accomplished by running the Elinktrace utility.
The Elinktrace program is located in :\Program Files\OVNM\Elink folder.
The following steps will change the tracing level from ERROR, which is the default value (Logging all ERROR
messages) to PROGRESS, (Trace all messages).
1. Turn the tracing off using the following command.
>cd \Program Files\OVNM\Elink
>elinktrace –off
2. Edit the Elink.cfg file in Notepad and modify the SET ELINK TRACE parameter to PROGRESS.
A part of the elinkcfg file has been provided for your reference.
#
# ELINK Configuration parameters.
#
SET ELINK TRACE PROGRESS
SET ELINK LOGFILE elink.log
SET ELINK REMOTEPORT 8976
SET ELINK LOCALPORT 8976
SET ELINK LOGFILELEN 500000
SET ELINK ALIVEPROBE 30
SET ELINK ALIVECOUNT 3
SET ELINK MAXSOCKETREADYTIME 60
Once the Elink.cfg has been modified, run Elinktrace to start tracing.
>elinktrace -on.
