HP XC System Software Administration Guide Version 3.1

Example A-3 Running Jobs as a User on an External Node Launching a Parallel Job
$ bsub -I -n6 -R type=SLINUX64 srun hostname
Job <413> is submitted to default queue <normal>.
<<Waiting for dispatch ...>>
<<Starting on xclsf>>
/home/test/.lsbatch/1113947197.413: line 8: srun: command not found
$ bsub -I -n6 -R type=SLINUX64 /opt/hptc/bin/srun hostname
Job <414> is submitted to default queue <normal>.
<<Waiting for dispatch ...>>

Note that srun was not found because the user's $PATH did not include /opt/hptc/bin, which is specific
to the HP XC system. There are several standard ways to address this if necessary (add /opt/hptc/bin
to the default $PATH on the node that does not belong to the HP XC system; or create a soft link to the
srun command from /usr/bin on all the nodes in the HP XC system).

A.10 Troubleshooting
• Use the following commands to verify your configuration changes:
— iptables -L and other options to confirm the firewall settings
— pdsh -a 'ls -l /etc/init.d/lsf' to confirm startup script
— pdsh -a 'ls -ld /shared/lsf/' (using our running example) to confirm that the LSF
tree was properly mounted
— pdsh -a 'ls -l /etc/profile.d/lsf.sh' to confirm the LSF environment scripts
• Monitor the LSF log files when problems arise for communication complaints, unresolved host name
issues, or configuration problems.
• Ensure that the HP XC firewall has been disabled properly. Having this enabled will prevent the
non-XC LSF nodes from communicating with the HP XC LSF node.
• Ensure that the controllsf command has been properly configured with alias. Run the controllsf
show command to confirm proper settings.
