Information You Need
When you run the clic_init command or use SMH for configuration, you have to provide
certain configuration information. So, before you run clic_init or use SMH, 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 11i v3 system and HyperFabric versions
earlier than B.11.31.00.
❏ For each HyperFabric adapter installed in the local node:
✓ The adapter’s IP address.
NOTE 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 SMH, 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 SMH, 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 101). You should note each adapter’s ID, because it is used as
input to other HyperFabric commands.
❏ For using the Transparent Local Failover feature of HMP available with this version
of HyperFabric, you need to define the card pairs.
❏ 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.
NOTE Remember, you cannot enable switch management through SMH—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 101). You should note each switch’s ID, because it
is used as input to other HyperFabric commands.
