SAS_lsm Utility config file Validation help

Setting up the SAS_lsm utility on our Linux Redhat deployment of SAS 9.4 M4. We have 3 Metatdata servers, 4 Grid Nodes and 2 Mid Tier servers and we would like to automate these Tiers as much as possible.

 

We are starting out with just trying to get a status of the Metadata servers but we are getting an error on the Validation of the configuration file when it starts. We installed the package on the meta01 server we have passwordless SSH configured from this server to all servers. we have all the parameters as stock as we can make it and it fails on the validation step as follows:

 

[sas@lxapp-cp-meta01 tools]$ ./SAS_lsm -s -c multi-tier.cfg

Configuration file validation [multi-tier.cfg] status [begin]
<<ERROR>> TIER[1]: ssh sas@lxapp-cp-meta01 -o 'BatchMode=yes' -o 'ConnectionAttempts=1' true
<<ERROR>> TIER[2]: ssh sas@lxapp-cp-meta02 -o 'BatchMode=yes' -o 'ConnectionAttempts=1' true
<<ERROR>> TIER[3]: ssh sas@lxapp-cp-meta03 -o 'BatchMode=yes' -o 'ConnectionAttempts=1' true
Configuration file validation [multi-tier.cfg] status [end failed - 000]

<<DEPLOYMENT STATUS>> Deployment tier services are in an unknown state
Please see /tmp/multi-tier.cfg/report.status for execution details

 

Any ideas what might be wrong on the configuration file?

Re: SAS_lsm Utility config file Validation help

Thanks for the quick response.  It does not appear that the issue is within the SAS_lsm configuration file based on the error message produced from the command execution of the ssh command:

 

Host key verification failed.

The problem does appear to be with the Linux ssh configuration.  Once addressed, you should be able to progress beyond the ssh heartbeat issue.  Side note, have you deployed and/or are using the SAS_lsm utility as root?  If so, you should be using your SAS installer userid...

Looks like the utility is tripping up on the ssh heartbeat test as it is probably returning a non zero return code.  Please run the following steps from the command line on the server where SAS_lsm is deployed:

 

1.  ssh sas@lxapp-cp-meta01 -o 'BatchMode=yes' -o 'ConnectionAttempts=1' true

2.  echo $?

 

and let me know what is displayed from both steps.

 

Regards

[root@lxapp-cp-meta01 UAT]# ssh sas@lxapp-cp-meta01 -o 'BatchMode=yes' -o
'ConnectionAttempts=1' true
Host key verification failed.
[root@lxapp-cp-meta01 UAT]# echo $?
