Hi Team,
I am getting below error while starting LASRMonitor process from SAS Compute node and the error details are below.
java.io.IOException
at com.sas.grid.broker.monitor.ConnectionManager.startTKGridMon(ConnectionManager.java:247)
at com.sas.grid.broker.core.BrokerCore.main(BrokerCore.java:267)
[ERROR@2020-06-17 11:42:41.618] Monitor thread failed to start due to configuration errors.
[ERROR@2020-06-17 11:42:41.619] No I/O produced by the grid monitor, check your SSH key configuration
I have resolved all SSH related issues and i am able to login to main node without password and vice versa to compute node from main node.
Please help me to resolve this issue or any help to understand more about this issue.
Best Regards,
Sandeep
The error seems to be related to SSH keys. How did you set them up? Its recommended to use HPA console. https://documentation.sas.com/?docsetId=hpaicg&docsetTarget=n03011sashpanalytics0install.htm&docsetV...
When you say compute, you mean the TkGrid Nodes? You should verify the SSH connectivity from head node (main node where VA is installed) to all the grid nodes and vice versa.
Try this to validate:
ssh node0.example.com
You should authenticate without any prompt for a password.
/opt/TKGrid/bin/simsh /opt/TKGrid/bin/simsh hostname
This also needs to complete without any errors or password prompts.
Successful output looks similar to this:
Hi Anand,
Thanks for the information.
I have set SSH keys manually and copied to all nodes.
I am getting the expected SSH output without any errors ,after running /opt/TKGrid/bin/simsh /opt/TKGrid/bin/simsh hostname.
Attached is the latest error after adding GRIDSHCOMMAND in sasv9_local.cfg file.
Best Regards,

The error shared by you is clearly highlighted in this KB article. https://support.sas.com/kb/60/126.html
If you are able to validate SSH connectivity from each node to every other node in cluster, I am not sure what's causing the issue. Would suggest to raise a SAS Technical support track by emailing the issue with error snaps and steps taken to support@sas.com
