HP XC System Software Administration Guide Version 3.2

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.
• Examine the output of the ifconfig command on the HP XC LSF node to ensure that the
LSF alias was properly established.
If eth0 is the external network device, the LSF alias entry is eth0:lsf.
• Use the appropriate LSF commands to restart daemons when network communications
have been adjusted:
— lsadmin reconfig to restart the Load Information manager (LIM)
— badmin mbdrestart to restart the Master Batch Daemon (mbatchd)
— badmin reconfig to reset the batch settings for the Slave Batch Daemon (sbatchd).
See the Platform LSF documentation for more information on these commands and Standard
LSF.
