Performing the Configuration
As explained in “Configuration Overview” on page 63, you must create the global
configuration file (/etc/rc.config.d/clic_global_conf) on each node in the fabric. This consists
mostly of specifying HyperFabric adapter-related information. (Note that if you are also
going to enable switch management—which we do not recommend doing—you need to
specify additional configuration information.)
NOTE Specifying configuration information adds or changes only the addresses and other
information in the global configuration file, based on the information you supply. It does
not perform any operations to check the relationships between that information and any
physical connections within the fabric.
You need to create the global configuration file in the following situations:
• You have just installed the HyperFabric hardware and software on the system.
• You want to change the information in the HyperFabric global configuration file (see
the Note above).
IMPORTANT Creating the global configuration file also modifies the /etc/rc.config.d/netconf file, adding
some HyperFabric-related lines that end with the characters #clic. These lines are used
by the HyperFabric software—and are not comments—so do not remove them from the
file.
You can create the global configuration file by using (1) the clic_init command (described
in the next section, “Using the clic_init Command”) or (2) SMH (described in “Using
SMH” on page 72). You cannot enable card pair or switch management through SMH
(you must use the clic_init command).
