Checking The Hyper-Threading Status For An Npartition - HP Rp7410 - Server - 0 MB RAM Administrator's Manual

core that can allow additional efficiencies of processing. For example, a dual-core processor with
Hyper-Threading active provides four logical processors, two on each processor core.
CAUTION: Some operating systems do not support Hyper-Threading. Problems can occur
when running an OS that does not support Hyper-Threading on an nPartition that has
Hyper-Threading enabled.
NOTE:
You must reset an nPartition when changing its Hyper-Threading status.
Hyper-Threading will not be enabled or disabled until after the nPartition is reset.

Checking the Hyper-Threading Status for an nPartition

status for an nPartition:
• From the EFI Shell: cpuconfig or cpuconfig threads
• From HP-UX: setboot
• Using the Enhanced nPartition Commands: parstatus -T
Example 7-2 Checking the Hyper-Threading Status for an nPartition
# setboot
Primary bootpath : 0/0/1/1/0.12.0
HA Alternate bootpath : 0/0/0/1/0
Alternate bootpath : 0/0/0/1/1
Autoboot is ON (enabled)
Hyperthreading : ON
: OFF (next boot)
#
The HP-UX setboot command indicates that Hyper-Threading currently is enabled (ON)

for the nPartition.
The next time the nPartition is booted (after it is reset), Hyper-Threading will be disabled
2
(OFF) for the nPartition.
Enabling Hyper-Threading for an nPartition
methods and then reset the nPartition whose Hyper-Threading status you have changed:
• From the EFI Shell: cpuconfig threads on
• From HP-UX: setboot -m on
• Using the Enhanced nPartition Commands: parmodify -pn -T y, where n is the nPartition
number.
• Using Partition Manager: Perform the Modify nPartition task and select the Enable
Hyper-Threading check box on the Configure Memory tab.
You must reset an nPartition after changing its Hyper-Threading status.
