If replacing an existing SCI adapter card, simply install the new card in the same
SBus slot.
If adding a new SCI adapter card, install it in an available SBus slot. If possible,
install the new card in the next higher slot. This will promote an orderly relationship
between SBus slot numbers and network ID values, which can simplify network
administration.
Connect New Adapter Card to Network
Connect the new card to the network, either directly to an SCI adapter in another
node or to a port on an SCI switch. See the sample two-, three-, and four-node
topologies illustrated in Figure 2–1, Figure 2–2, and Figure 2–3.
Create a Temporary Network Map
Either update the temporary network map that was made when the network was
created or last changed or create a new temporary network map as described in
Chapter 3. Include the new adapter card in the map, identifying its SBus location
and serial number.
Run
sciconf
Run the command
sciconf
as root on the node that contains the new SCI adapter
card. This will initialize the card so it can be used by the local SCI driver software. In
the following example,
sciconf
is run on a node that has been added to an existing
network. This node contains a single SCI adapter whose serial number is 6269. The
sciconf
output indicates the network ID and SBus slot of this SCI adapter.
