NOTE
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
❏For each HyperFabric adapter installed in the local node:
✓The adapter’s IP address.
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.
Remember, you cannot enable switch management through
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.
