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 SAM—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.)

•Whether the node can interoperate with nodes that are using any HP-UX 10.20 version of HyperFabric, any HP-UX 11.0 HyperFabric versions earlier than B.11.00.11 or any HP-UX 11i HyperFabric versions earlier than B.11.11.01.

We recommend 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 SAM (on HP-UX 11.0 and 11i only) to configure each HyperFabric adapter.

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

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

IMPORTANT: In this file, clic_init and SAM 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 92. Using SAM to configure an adapter is described in “Using SAM—HP-UX 11.0 and HP-UX 11i” on page 94.

After you have used the clic_init command or SAM, you can configure HyperFabric with MC/ServiceGuard, if necessary. See “Configuring HyperFabric with MC/ServiceGuard” on page 98 for more information.
