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 have 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 11.0
HyperFabric versions earlier than B.11.00.11 or any HP-UX 11i v1
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. You can also determine an
adapter’s ID by running the clic_stat command (see “The clic_stat
Command” on page 133). 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
in the version B.11.11.03 of HyperFabric, you need to define the card
pairs.
❏ For each HyperFabric switch in the fabric (if you are going to enable
switch management):
