Configuration
Creating the PRM Configuration File /etc/prmconf
The PRM configuration is contained in the ASCII file /etc/prmconf.
Use the prmloadconf command to create a template. Specify a file name using the –f option.
Default file name is /etc/prmconf:
$ prmloadconf [-f file]
This template needs to be modified. In this example the configuration looks as follows (detailed
syntax in the table below):
$ cat /etc/prmconf
