power_system – PowerOn, PowerOff, modify_syscfg, modify_hwres, facts of the Managed system

Synopsis

Poweron specified managed system

Poweroff specified managed system

Modify System configuration of the specified managed system with specified configuration details

Modify hardware resource of the specified managed system with specified hardware resource details

Get the facts of the specified managed system

Enable and Disable PCM metrics

Parameters

hmc_host (True, str, None)

The IPaddress or hostname of the HMC.

hmc_auth (True, dict, None)

Username and Password credential of the HMC.

username (True, str, None)

Username of the HMC to login.

password (optional, str, None)

Password of the HMC.

system_name (True, str, None)

The name of the managed system.

new_name (optional, str, None)

The new name to be configured on specified system_name.

This option works with modify_syscfg action.

power_off_policy (optional, int, None)

power off policy to be configured on specified system_name.

This option works with modify_syscfg action.

Configuring this option to ‘1’ will power off the Managed System after all partitions are shutdown.

power_on_lpar_start_policy (optional, str, None)

power on partition start policy to be configured on specified system_name for the next system restart.

This option works with modify_syscfg action.

requested_num_sys_huge_pages (optional, int, None)

Configures the number of pages of huge page memory.

User can change this value only when the managed system is powered off.

This option works with modify_hwres action.

mem_mirroring_mode (optional, str, None)

Configures the memory mirroring mode on specified system_name for the next system poweron or system restart.

User can use this option on only managed systems which supports memory mirroring.

This option works with modify_hwres action.

pend_mem_region_size (optional, str, None)

Configures the memory region size setting on specified system_name.

choices are in MB.

This option works with modify_hwres action.

metrics (optional, list, None)

Provides five types of utilization data

Long Term Monitor(LTM), Short Term Monitor(STM), Aggregated metrics(AM), ComputeLTM(CLTM), EnergyMonitor(EM).

AM collects data from LTM and EM, hence when the AM is enabled automatically LTM and EM will be enabled.

When LTM or EM is disabled then automatically the AM will also get disabled.

This option works only with enable_pcm and disable_pcm action.

action (optional, str, None)

poweroff poweroff a specified system_name.

poweron poweron a specified system_name.

modify_syscfg Makes system configurations of specified system_name.

modify_hwres Makes hardware resource configurations of specified system_name.

enable_pcm Enables the Performance and Capacity Monitoring for specified types of utilization data.

disable_pcm Disables the Performance and Capacity Monitoring for specified types of utilization data.

state (optional, str, None)

facts fetch details of specified system_name

Notes

Note

• All operations except facts support passwordless authentication.
