HP XC System Software Installation Guide Version 3.0

It is possible to actually view an installation through the remote serial console, but to do so, you must edit
the /tftpboot/pxelinux.cfg/default file before the installation begins and add the correct serial
console device to the APPEND line. If this is done, the cmfd services should be disabled and a smaller group
of nodes should be imaged at any one time. The network traffic caused by the serial console can adversely
affect the imaging operation.
Troubleshooting Licensing Issues
This procedure describes what to do if you did not have the XC.lic license file in place before you ran the
cluster_config utility, which means that LSF does not function.
1. Begin this procedure as the root user on the head node.
2. Use the file copy utility of your choice (such as scp) to copy the XC.lic file to the
/opt/hptc/etc/license directory on the head node.
3. Make sure the file permissions are set to only allow root to have read and write access:
# chmod 600 /opt/hptc/etc/license/XC.lic
# ls -l /opt/hptc/etc/license/XC.lic
-rw------- 1 root root 941 Dec 20 10:34 XC.lic
4. Stop and start the license daemon:
# service hptc-lm stop
# service hptc-lm start
5. Determine the node on which LSF is running:
# controllsf show current
LSF is currently running on n16 and assigned to node n16
6. Log in to the node where LSF is running.
7. Restart the LSF LIM daemon:
# pkill lim
#lsadmin limstartup
Checking configuration files ...
No errors found
Restart LIM on <lsfhost.localdomain> ...... Done
Troubleshooting the Software Upgrade Procedure
The following list provides hints to troubleshoot problems you might encounter when upgrading the HP XC
System Software from a previous release to this release:
• Look at the upgrade log files to determine if there were any upgrade failures. Table K-2 (page 146) lists
the log files that are generated during a software upgrade.
