_________________________ Note _________________________
Only perform this procedure when you have exclusive use of the HP XC system
and when no jobs are running on the system because the procedure requires that
you reimage nodes.
This procedure ad ds a service called newservice to the common role:
1. Log in as the superuser on the h ead node.
2. Copy the roles_services.ini file:
# cd /opt/hptc/config
# cp role_services.ini role_services.ini.BAK
3. Determine the role that best suits the new service.
Use the shownode servers command to determ in e which nodes currently provide the
services for that role. This command is described in Section 3.2.2.
4. Edit the roles_services.ini file as follows:
a. Add the name of the new service to the stanza that lists the s ervices.
services = <<EOT
