This section explains how to start and stop individual processors in a multiprocessing server. Only secondary processors can be handled this way.
When the Platform Support Module (PSM) is loaded in the startup.ncf file and the Auto Start Processors Set parameter value (Multiprocessor category) is set to On, NetWare can start the secondary processors automatically.
NOTE:Server console commands for processors affect only secondary processors. Processor 0 cannot be taken offline while the server is running.
You can start or stop or display information about secondary processors at any time while the server is running using the following procedures.
Before starting or stopping a process, you should display the processor information to determine the status of the processor. The following utilities are available to display processor information.
Click the link under the heading in the navigation frame.
View the information on the Processor Information page.
From this page you can view whether the processor is online or offline, start or stop a processor, and view the following information about each processor:
Speed, family, model, and stepping
Feature flags and CPUID
L1 and L2 cache
The amount of TLB Instruction and Data entries
The following table specifies the commands to use at the System Console prompt to determine processor status.
Table 5-7 Determining Processor Status by Using Commands at the System Console Prompt
For more information, see DISPLAY PROCESSORS
and CPUCHECK
in NW 6.5 SP8: Utilities Reference.
Per-processor statistics are also available from Monitor. From the Available Options menu, select > .
Processor 0 is the boot processor and cannot be taken offline.
When a secondary processor is taken offline, the threads running on that processor are switched to another processor automatically.
You can stop processors using Novell Remote Manager or server console commands at the System Console prompt.
To bring a secondary processor offline in Novell Remote Manager:
Click the link under the Manage Hardware heading in the navigation frame.
Click the link for the applicable processor that you want to stop.
The following table specifies the commands to use at the System Console to take a processor offline.

For more information, see DISPLAY PROCESSORS
and STOP PROCESSORS
in the NW 6.5 SP8: Utilities Reference.
The NetWare default is to start secondary processors automatically when the server boots. If a secondary processor is offline, you can bring in online by using Novell Remote Manager or server console commands at the System Console prompt.
To bring a processor online in Novell Remote Manager:
Click the link under the Manage Hardware heading in the navigation frame.
Click the link for the applicable processor that you want to start.
The following table specifies the commands to use at the System Console to bring a processor online.
