The InfiniBand switch controller card provides access to InfiniBand switch control functions through an Ethernet connection. The controller card runs a process that collects configuration and status information from the switch.

Table D-4 provides the switch names and associated IP addresses you need during the configuration procedure. Other switch naming conventions can be used depending on switch topology.

Important Note About HP Server Blades and Enclosures:

If the hardware configuration contains HP server blades and enclosures, the IP addresses for the switch monitoring cards is based on the swBase address in the base_addrV2.ini file. Therefore, the IP addresses shown in Table D-4 do not apply.

For more information about these IP addresses for HP server blades, see the HP XC Systems With HP Server Blades and Enclosures HowTo, which is available at the following Web site:

http://www.docs.hp.com/en/highperfcomp.html

Table D-4 InfiniBand Switch Controller Card Naming Conventions and IP Addresses

Switch OrderSwitch Name IP Address
First switchIR0N00172.20.66.1
Second switchIR0N01172.20.66.2
Third switchIR0N02172.20.66.3
Last switchIR0N0n172.20.66.n

 

Follow this procedure to configure network access to the InfiniBand switch controller card:

  1. Ensure that an Ethernet cable from the monitoring line card's primary Ethernet port is connected to the appropriate Ethernet port on the Root Administration Switch. This connection is described in the HP XC Hardware Preparation Guide.

  2. Connect to the switch controller by plugging a serial cable into the serial port on the switch and using a terminal emulation program, such as HyperTerminal. You must use terminal settings of a baud rate of 38400, 8 data bits, no parity, 1 stop bit and no flow control.

  3. Press the Enter key to access the character cell interface to the switch.

  4. Log in to the switch with the default user name and password:

    login# admin
    Password# 123456
  5. Access the enable mode with the default password (voltaire):

    ISR-9024# enable
    Password# voltaire
  6. Change the default admin password:

    ISR-9024# password update admin
  7. Change the default enable password:

    ISR-9024# password update enable
  8. Access the configuration mode:

    ISR-9024# config
  9. Access the interface fast mode:

    ISR-9024(config)# interface fast
  10. Set the IP address of the switch and the netmask using the data in Table D-4 as a reference. Set the netmask to 255.255.0.0 as shown:

    ISR-9024(config-if-fast)# ip-address-fast set IP_address 255.255.0.0
  11. Confirm the settings:

    ISR-9024(config-if-fast)# ip-address-fast show
  12. Exit the interface fast mode:

    ISR-9024(config-if-fast)# exit
  13. Access the route mode:

    ISR-9024(config)# route
  14. Set the gateway IP address, which is the internal IP address of the head node:

    ISR-9024(config-route)# default-gw fast set IP_address
  15. Confirm the gateway IP setting:

    ISR-9024(config-route)# default-gw show
  16. Exit the route and configuration modes:

    ISR-9024(config-route)# exit
    
  17. Enable the switch to generate error reports:

    ISR-9024(config)# sm
    ISR-9024(config-sm)# pm
    ISR-9024(config-sm-pm)# pm report-enable set enable
    ISR-9024(config-sm-pm)# pm reset-counters set
    ISR-9024(config-sm-pm)# exit
    ISR-9024(config-sm)# exit
  18. Set the switch time to be closely synchronized with the system time (within 1 minute). Replace MMDDhhmmYYYY with the actual system time:

    ISR-9024(config)# exit
    ISR-9024# clock set MMDDhhmmYYYY

    For example, to set the system date and time to 2:42 p.m. on September 29, 2006, enter the following command:

    ISR-9024# clock set 092914422006
  19. Reset the switch to save the settings you just made:

    ISR-9024# reload
  20. Log in as the root user on the head node.

  21. Use the text editor of your choice to open the /etc/hosts file and add an entry for each switch. For example, if you have one switch, the entry is similar to the following:

    172.20.66.1    IR0N00							

    Use the number zero (0), not the letter O, in the host name IR0N00. Make the 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
  22. Save your changes and exit the file.

  23. Repeat this entire procedure for each switch controller card, modifying the host name and switch address using the data in Table D-4 as a reference.

After completing this procedure, you can access the switch controller cards using either the switch name or IP address:

# telnet IR0N00

When the connection is established, use the password you set in step 6 to log in to the switch controller.
