Prepare to Edit hpc.conf

Perform the steps described in "Stop the CRE Daemons" and "Copy the hpc.conf Template".

Stop the CRE Daemons

Stop the CRE nodal and master daemons (in that order). The nodal daemons must be stopped on each node, including the master node.

You can use one of the CCM tools (cconsole, ctelnet, or crlogin) to broadcast the nodal stop command to all the nodes from a single command entered on the master node.

Use the following scripts to stop the CRE nodal and master daemons:

# /etc/init.d/sunhpc.cre_node stop# /etc/init.d/sunhpc.cre_master stop

If you edit the hpc.conf file at a later time and make any changes to the PFSServers section or PFSFileSystem section, you will need to also unmount any PFS file systems and stop the PFS daemons on the PFS I/O servers before making the changes.

Copy the hpc.conf Template

The Sun HPC ClusterTools 3.0 distribution includes an hpc.conf template, which is stored, by default, in /opt/SUNWhpc/examples/cre/hpc.conf.template.

Copy the template from its installed location to /opt/SUNWhpc/conf/hpc.conf and edit it as described in "Create PFS I/O Servers".

When you have finished editing hpc.conf, perform the steps described in"Update the CRE Database" to update the CRE database with the new configuration information.
