Conﬁguring HyperFabric

Conﬁguration Overview

Conﬁguration Overview

You do not need to conﬁgure the HyperFabric switch because the HyperFabric

management process performs automatic routing and conﬁguring for the switch. So,

conﬁguring HyperFabric consists only of creating the HyperFabric

/etc/rc.config.d/clic_global_conf global conﬁguration ﬁle on each node in the fabric. The

conﬁguration ﬁle contains the following information:

• The IP addresses and subnet mask of the HyperFabric adapters installed in the

node.

• For each HyperFabric switch in the fabric—the switch’s IP address, and the MAC

address of the switch’s Ethernet port. Note that this applies only if you enable switch

management. Also note that you cannot enable switch management through

SMH—you must use the clic_init command.

• The IP multicast address that all the switches and nodes in the fabric will register to

(if you are going to enable switch management).

• The IP address of the local node’s Ethernet LAN interface. This LAN interface must

be on the same subnet as the Ethernet port(s) of the HyperFabric switch(es) (if you

are going to enable switch management). (Note that a node might have multiple

LAN interfaces.)

NOTE HP recommends that you do not enable switch management.

You can create the global conﬁguration ﬁle by either (1) running the clic_init command or

(2) using SMH to conﬁgure each HyperFabric adapter.

clic_init and SMH also put the necessary entries into the following three ﬁles:

• The system /etc/rc.config.d/netconf ﬁle.

NOTE In this ﬁle, clic_init and SMH add 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.

• The system /etc/rc.config.d/clic_global_conf ﬁle.

• The /etc/rarpd.conf (Reverse Address Resolution Protocol [RARP]) support ﬁle. This

ﬁle is used in the management of the HyperFabric switches (if you are going to

enable switch management).

The clic_init command is described in “Using the clic_init Command” on page 70. Using

SMH to conﬁgure an adapter is described in “Using SMH” on page 72.

After you have used the clic_init command or SMH, you can conﬁgure HyperFabric with

ServiceGuard, if necessary. See “Conﬁguring HyperFabric with ServiceGuard” on

page 76 for more information.
