Using the clic_init Command
Run the clic_init command to create the global configuration file.
IMPORTANT If the global configuration file already exists and you are running clic_init again (to
change the file), you have the option of retaining or modifying the existing configuration
information, in addition to adding new information pertaining to new hardware.
Also, once you’ve completed your changes and clic_init ends its processing, you must
stop HyperFabric (by running the clic_shutdown command or using SAM) and then
start HyperFabric (by running the clic_start command or using SAM). Otherwise,
your configuration information changes will not take effect. See “Stopping HyperFabric”
on page 99 and “Starting HyperFabric” on page 85 for more information.
If you include /opt/clic/bin in your PATH statement, you can run the command as it is
shown below. Otherwise, you must include /opt/clic/bin as part of the command name
(that is, /opt/clic/bin/clic_init).
You must be logged in as root to run this command.
The syntax is as follows:
clic_init [-c] [-?]
where
• -c specifies that you want to create the global configuration file. You are prompted
for the information described in “Information You Need” on page 86. Note that if the
global configuration file already exists (for example, when you are adding an adapter
to an existing fabric), clic_init prompts you with the existing configuration
information. As you are prompted with each piece of information, you can then
confirm that you want to keep it or you can change it.
• -? displays the online help for clic_init.
If you do not specify any of the above parameters, the online help for clic_init is
displayed.
After you have entered the information for all the adapters in the node and all of the
switches (if any) in the fabric, a summary of the configuration information is displayed.
Once clic_init has finished, you do one of the following things:
• If you want to configure HyperFabric with MC/ServiceGuard, complete the
configuration described in “Configuring HyperFabric with MC/ServiceGuard” on
page 98, then run clic_start or use SAM to start HyperFabric.
• If you have just created the global configuration file on the local node for the first
time (and you are not configuring MC/ServiceGuard), run clic_start or use SAM to
start HyperFabric.
• If you have just changed an existing configuration file on the node, run
clic_shutdown or use SAM to stop HyperFabric, and then run clic_start or use
SAM to start HyperFabric. Until you do those two things, your configuration changes
will not take effect.
See “Stopping HyperFabric” on page 99 and “Starting HyperFabric” on page 85 for more
information.
