Configuring HyperFabric
Information You Need
Chapter 472
✓ 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.
See Figure 3-2 on page 66 for the location of the label on the HF
switch, and Figure 3-2 on page 59 and Figure 3-3 on page 60 for
the location of the label on the HF2 switch.
IMPORTANT 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 117). 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).
❏ For each node in the fabric, you need the IP address of the node’s
Ethernet LAN interface that is on the same subnet as the switches.
(As mentioned earlier, a node might have multiple LAN interfaces.)
Note that if you do not have switch management enabled, you do not
need this information (clic_init will not prompt you for it).
As stated earlier, HP recommends that you do not enable switch
management.
IMPORTANT You should also check your /etc/hosts file — when you are using files
for host name look up — to ensure that the entries for all of the systems
are in the correct format: the official host name, which is the full domain
extended host name, and any alias names. For example:
