Connecting Two Server Systems

60
Before connecting two Origin 350 server systems to each other, you must assign unique
system ID numbers to the servers, as follows:
1. Designate one of the servers as the master server and the other server as the slave.
2. Connect a console to the slave server (see "Connecting the System Console" on
page 51), and power on the server (see "Powering the Server System On and Off"
on page 53).
3. Use the brick slot <slotnumber> L1 command to set the slave system ID
number to a higher number than the master system ID number. For example, if the
master server's L1 prompt indicates that its ID number is 01 (
slave system ID number should be 02 or higher (
001c01-L1>brick slot 02
brick slot set to 02.
See the SGI L1 and L2 Controller Software User's Guide (007-3938-00x) for more
information on L1 commands.
To connect two Origin 350 server systems to each other with a NUMAlink 3 cable, follow
these steps:
1. Power off both servers (see "Powering the Server System On and Off" on page 53).
2. Connect the NUMAlink 3 cable to the NUMAlink connectors on both servers.
3. Connect a system console to the master server, as described in "Connecting the
System Console" on page 51.
4. Power on both servers as described in "Powering the Server System On and Off" on
page 53.
The console output should indicate that the processors and memory on both servers have
been discovered. If the slave server has not been discovered, use the reset L1 command
to perform a reset of the system.
Note: For server-to-server communication to work correctly, the network mode on the
server must be set to 422 (when connecting a PC [system console] to a serial port). Use
the network L1 command to set the network mode. (See the SGI L1 and L2 Controller
Software User's Guide (007-3938-00x) for more information on L1 commands.)
