The Quadrics switch controller card provides access to Quadrics
switch control functions through an Ethernet connection. The controller card
runs a process that collects configuration and status information from the
switch.
Table D-1 and Table D-2 provide the switch names
and associated IP addresses you need for the configuration procedure. The
IP addresses for the switch monitoring line cards is based on the swBase address
in the base_addr.ini file. The default address base for
the switch monitoring line cards is 172.20.66, but if you modified the swBase value,
the address base for the switch monitoring line cards must change accordingly.

|
 | NOTE: For more information about configuring the Quadrics switch
controller card, see the HP Cluster Platform Quadrics QsNetII Interconnect reference
guide, which is available on the hardware documentation CD. Your cluster
platform customer letter provides instructions for loading the documentation
CD and accessing the documentation through the online guide. |

Ensure that an Ethernet cable from
the monitoring line card's primary Ethernet port is connected to an Ethernet
port on the Root Administration Switch. This connection is described in the HP XC Hardware Preparation Guide.
Connect to the switch controller using
a VGA monitor and keyboard or a connection to the serial port using a null
modem cable and a terminal or terminal emulation program such as HyperTerminal.
Connecting to the switch controller displays the Quadrics Switch
Control main menu, which is similar to the following:
Quadrics Switch Control -- (QR0N00)
1. Show network settings
2. Change network settings
3. Run jtest
4. Set module mode
5. Firmware upgrade
6. Quit
7. Reboot
8. Access Settings
9. Self Test
Enter 1-9 and press return: |
Enter 2 to
access the Change network settings menu option
and set the switch to STATIC IP addresses:
Quadrics Switch Control
Select Protocol
1. BOOTP
2. STATIC
3. Abort
Enter 1,2,3 and press return [2]: 2
Setting to STATIC
Enter rail: 0
Enter type (N for Node, S for Supertop, T for Top) (q to abort): N
Enter location (0-127) (q to abort): 0
Setting switch name to default: QR0N00
Setting IP address by switchname
Enter IP address [default 172.20.66.1] q to abort: Enter
Enter netmask address [default 255.255.0.0] q to abort: your_netmask
Enter gateway address [default 172.20.0.254], q to abort: Enter
Enter TFTP/RIS server IP address [default 172.20.0.254] q to abort: Enter
Enter TFTP upgrade filename [default 503-upgrade.tar] (q to abort): Enter
Setting upgrade filename to default: 503-upgrade.tar
Network Setup complete.
NOTE: REBOOT required for settings to take effect Press return to return to
main menu |
Select the Show network
settings menu option to obtain the line card MAC address. Write
down this address for use later in this procedure.
Select the Access
Settings menu option, and select the Password settings option
to set a login password for the switch.
Select the Access
settings menu option again, and select the Access
protocol settings option to enable the ssh command.
Reboot the switch controller from
the Reboot menu.
Log in as the root user
on the head node.
Use the text editor of your choice
to open the /etc/hosts file and add an entry for each
switch, using the data in Table D-2 as
a reference. For example, if you have one switch, the entry is similar to
the following:
Make your entries above the following line in the file
because any entries that follow this line will be deleted if you reconfigure
the system:
#XC-CLUSTER Do Not Edit Below this Line |
Save your changes and exit the file.
Repeat this entire procedure for each
switch controller card, modifying the switch name and switch address using
the data in Table D-2 as a
reference.
After completing this procedure, you can access
the switch controller cards using either the switch name or IP address:
When the connection is established, use the Quadrics login
password you set in step 5 to log
in to the switch controller.
