Adding a Group
To add a load balancing group, follow these steps:
1Install the NICs.
Follow the procedures in “Installing and Connecting the NIC” on page 18.
Connect all NICs in the group to the same network.
2Make the following changes to the AUTOEXEC.NCF file:
■Add or verify the LOAD commands for the LAN drivers for all slot-frame instances.
■In each group, load the same protocols and frame types on the primary and all
secondary NICs.
■On the primary NIC only, bind a protocol to each slot-frame instance.
■Remove any BIND commands from each secondary NIC.
■For each group, add an LBRSL GROUP command to bind the primary and secondary
NICs together. There can be only one LBRSL GROUP command per group, and it
must list the primary and all secondary NICs. Place this command after the LAN
driver LOAD commands or the SYS:ETC\INITSYS.NCF command. To specify a load
balancing group with resilient server links, use the LB option. To specify a resilient
server link group without load balancing, use the RSL option.
For the LBRSL GROUP command syntax, see “Server Feature Commands” on
page 69.
