Configuring Groups
35
■
Decide whether you want to use a foreign NIC in one of the groups.
Two foreign NICs (two that are not 3Com EtherLink Server NICs) are allowed in
one group per server.
■
Decide which NIC is to be the primary NIC in each group.
■
Decide whether groups are to perform load balancing:
■
Load balancing groups provide failover and share the network load.
■
Resilient server link groups provide failover, but do not share the network
load.
■
To use bidirectional load balancing, you must assign a dedicated IP address for
each load balancing group. This address must be unique (not used elsewhere
on the network).
■
Obtain the slot numbers of the NICs. You need these numbers if you are
installing more than one NIC. See
Obtaining Slot Numbers on page 27
instructions.
Adding a Secondary NIC
to a Group
1
Install the new secondary NIC.
Follow the procedures in
Installing and Connecting the NIC on page 7
Connect the new secondary NIC to the network that is used by the group.
2
Make the following changes to the AUTOEXEC.NCF file:
■
Add or verify the LOAD commands for the LAN drivers for all slot-frame
instances.
■
Load the same protocols and frame types on the new secondary NIC.
■
Add the slot number of the new secondary NIC to the LBRSL GROUP
command.
3
Reboot the server.
The sample AUTOEXEC.NCF file in
shows a group of three NICs. The
primary NIC in slot 10001 is bound to two secondary NICs in slot 10002 and
slot 10003.
