Showing CPU Power-Managed Strands

This section shows how to list power-managed strands and virtual CPUs.

List CPU Power-Managed Strands

List power-managed strands by doing one of the following.

Use the list -l subcommand.

A dash (---) in the UTIL column of the CPU means the strand is power-managed.

# ldm list -l primary
NAME         STATE   FLAGS  CONS  VCPU MEMORY  UTIL  UPTIME

VCPU
    VID    PID    UTIL STRAND
    0      0      0.0%   100%
    1      1      ---    100%
    2      2      ---    100%
    3      3      ---    100%
    4      4      ---    100%
    5      5      ---    100%
    6      6      ---    100%
    7      7      ---    100%
....

Use the parseable option (-p) to the list -l subcommand.

A blank after util= means the strand is power-managed.

# ldm list -l -p
 
VCPU
|vid=0|pid=0|util=0.7%|strand=100
|vid=1|pid=1|util=|strand=100
|vid=2|pid=2|util=|strand=100
|vid=3|pid=3|util=|strand=100
|vid=4|pid=4|util=0.7%|strand=100
|vid=5|pid=5|util=|strand=100
|vid=6|pid=6|util=|strand=100
|vid=7|pid=7|util=|strand=100

List Power-Managed CPUs

List power-managed CPUs by doing one of the following.

Use the list-devices -a cpu subcommand.

In the power management (PM) column, a yes means the CPU is power-managed and a no means the CPU is powered on. It is assumed that 100 percent free CPUs are power-managed by default, hence the dash (---) under PM.

# ldm list-devices -a cpu
VCPU
   PID     %FREE      PM
   0       0          no
   1       0          yes
   2       0          yes
   3       0          yes
   4       100        ---
   5       100        ---
   6       100        ---
   7       100        ---

Use the parseable option (-p) to the list-devices -a cpu subcommand.

In the power management (pm=) field, a yes means the CPU is power-managed and a no means the CPU is powered on. It is assumed that 100 percent free CPUs are power-managed by default, hence the blank in that field.

# ldm list-devices -a -p cpu
