Adjust Reserve Power Supply Count Using the ILOM CLI

The following procedure explains how to change the number of reserve power supply modules (Reserve PSU Count) using the ILOM CLI.

What To Do

  1. Log in as root to the CMM using the ILOM CLI.

  2. At the command prompt, type:

    -> show /CMM/powermgmt

    The CMM’s power management targets and properties appear. For example:

    -> /CMM/powermgmt
    	Targets:
    		1 (Consumed Power)
    		2 (Ticketed Power)
    		3 (Available Power)
    		4 (Reserve Power)
    		5 (/CH/BL3 Consumed Power)
    		6 (/CH/BL6 Consumed Power)
    		7 (/CH/BL9 Consumed Power)
    		8 (Other Consumed Power)
    	Properties:
    		reserve_psus = 2
    		total_psus = 4
    	Commands:
    		cd
    		set
    		show
  3. To change the number of reserve power supply modules (reserve_psus), type the following command:

    -> set reserve_psus=n

    Where n equals the number of power supply modules set as reserve units.

    Use the cd command to view the changed reserve_psus value. For example:

    -> cd /CMM/powermgmt
    	/CMM/powermgmt
    		-> set reserve_psus=1

    Note

    If you set the value of the Reserve PSU Count too high, the following message is displayed: set: Failed to set reserve PSU count: chassis Available Power must exceed chassis Ticketed Power to prevent power over subscription.
