This section illustrates the procedure for configuring or activating a processor for the V-Class.

For additional information on the V-Class boot sequence and other operating instructions please consult the V2500 Server Operator’s Guide at: docs.hp.com/hpux/hw under V-Class.

  1. Reboot the system from the system console either remotely or from the V-Class test station.

  2. Access the V-Class boot menu interface. If autoboot is disabled the system displays the boot menu by default; otherwise, interrupt the boot process when prompted by pressing any key.

    [0] Command:

  7. Reset the system to configure the processors. Enter the command RESET. Boot the system to the HP-UX prompt.

    [0] Command: RESET

  8. At the system prompt, activate the configured processors with the icod_modify command (see “Increasing Processor Capacity”).

  9. Verify that the processors are available with the ioscan
    HP-UX command. Note the information provided by ioscan on the number of active processors is different from that reported during configuration.

    /> ioscan -fk|grep -i proc
     
    processor   0  16          processor   CLAIMED     PROCESSOR    Processor
    processor   1  18          processor   CLAIMED     PROCESSOR    Processor
    processor   2  24          processor   CLAIMED     PROCESSOR    Processor
    processor   3  26          processor   CLAIMED     PROCESSOR    Processor
    processor   4  32          processor   CLAIMED     PROCESSOR    Processor
    processor   5  34          processor   CLAIMED     PROCESSOR    Processor
    processor   6  40          processor   CLAIMED     PROCESSOR    Processor
    processor   7  42          processor   CLAIMED     PROCESSOR    Processor 
    />

This completes the processor offline configuration and activation process for the HP-UX V-Class server.

NOTE:

Deconfiguring Processors. To deconfigure a processor, refer to the Title not available and use the reverse order of the configuration sequence.
