Information You Need
When you run the clic_init command or use SAM for configuration, you have to
provide certain configuration information. So, before you run clic_init or use SAM,
you should get the following information:
❏ For each node in the fabric, determine if that node will need to interoperate with
other 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.
❏ For each HyperFabric adapter installed in the local node:
✓ The adapter’s IP address.
IMPORTANT: The last 10 bits of each adapter’s IP address must be unique
throughout the entire fabric. And, remember that the last part of the address
cannot be 0 (that is, the IP address cannot be n.n.n.0). Also, note that
HyperFabric converts these 10 bits to a decimal value called the Virtual Route
IDentifier (VRID), which is used in some HyperFabric command input and
output.
✓ The subnet mask. When you run clic_init or use SAM, if you do not specify a
value for this, a default subnet mask is chosen based on the adapter’s IP address.
When clic_init begins to prompt you for the information for each adapter, it
assigns an ID (for example, clic0) to that adapter and displays it as part of the first
prompt. If you use SAM, it assigns the adapter an ID and displays it in the “Adapter
Name” column of the “Configure HyperFabric Adapter” screen. Note that you can
also determine an adapter’s ID by running the clic_stat command (see “The
clic_stat Command” on page 91). You should note each adapter’s ID, because it is
used as input to other HyperFabric commands.
❏ For each HyperFabric switch in the fabric (if you are going to enable switch
management):
✓ The IP address of the switch.
✓ The MAC address of the switch’s Ethernet port. If you do not already know the
switch’s MAC address, it is printed on a label on the back of the HF switch and
on the front of the HF2 switch.
IMPORTANT: Remember, you cannot enable switch management through
SAM—you must use the clic_init command.
When clic_init begins to prompt you for the information for each switch, it assigns
an ID (for example, sw_clic0) to that switch and displays it as part of the first
prompt. Note that you can also determine a switch’s ID by running the clic_stat
command (see “The clic_stat Command” on page 91). You should note each switch’s
ID, because it is used as input to other HyperFabric commands.
❏ For the entire fabric, you need the IP multicast address that all the switches and
nodes in the fabric will register to. The address must be a class D address. Note that
if you do not have switch management enabled, you do not need this information
(clic_init will not prompt you for it).
