Analyzing Processor Sockets and Cores
8-11
8.10.1. Disabling Processor Sockets using remote console interface
Disabling a processor socket means that socket cannot support a processor. This
reduces the total number of processor cores by six for each socket that is disabled. To
disable processor sockets manually
1. Navigate to the fault information page of the remote console interface for a partition
(refer to Figure 3-19 ).
The lower portion of the page lists components by cell and shows them as being
either enabled or disabled. The processor sockets are labeled IP 0, IP 1, IP 2, and
IP 3 for each cell.
2. Scroll to each desired cell and processor socket, and select Disabled.
3. Click Submit .
4. Power up the partition (or restart it if it is running) to boot it without the disabled
sockets.
8.10.2. Disabling Processor Cores using BIOS Interface
Disabling a processor core means that core is not available for the operating system to
use. This reduces the total number of processor cores by one for each core that is
disabled. To disable processor cores manually
1. Power on the partition.
A logo screen appears for a few seconds, with an instruction at the bottom to press
the space bar to enter BIOS.
2. Press the space bar while the logo screen is displayed.
The BIOS front page appears, as shown in Figure 5-1 .
3. Select BIOS Setup and press Enter.
The BIOS Setup window appears, as shown in Figure 5-5 .
4. Select Partition and press Enter.
The Partition window appears, as shown in Figure 5-7 .
5. Select Processor Configuration and press Enter.
The Processor Configuration window appears, as shown in Figure 5-13 .
6. Select the cell for which you want to disable processor cores and press Enter.
The processor cores selection window for the cell appears, as shown in Figure 8-3 .
The cores for each socket are listed. Cores that are enabled are marked with X.
