Storing Customer Information

This section describes ILOM features that enable you to store information (for purposes such as inventory control or site resource management) on the SP and FRU PROMs.

To Change Customer FRU Data Using the CLI

Use the /SP customer_frudata property to store information in all FRU PROMs.

Type:
-> set /SP customer_frudata=”data”
Note - The data string (“data”) must be enclosed in quote marks.

To Change System Identification Information Using the CLI

Use the /SP system_identifier property to store customer identification information.

Type:

-> set /SP system_identifier=”data”

To Change Customer Identification Information Using the Web Interface

ILOM provides features that enable you to store information on FRUs and the SP.

Log into the ILOM web interface as Administrator (root) to open the web interface.

Select System Information --> Identification Information.

Edit the Customer FRU data field.

View the SP Hostname.

Edit the SP System Identifier field.

Changing Service Processor Settings to Factory Defaults

This section describes how to set service processor settings back to the factory defaults.

To Reset the Service Processor Settings to Factory Default Values Using the CLI

Use the reset_to_defaults property to set all ILOM configuration properties back to their factory default values. The all option sets the ILOM configuration and all user information back to the factory default values.

At the -> prompt, type the following command:
-> set /SP reset_to_defaults=all
where for reset_to_defaults can be set to one of the following:
- none – Make no changes.
- configuration – Preserve the user database.
- all – Reset (clear) the user database.

Reset the service processor so that the new property value can take effect.

To Reset the Service Processor Settings to Factory Defaults Using the Web Interface

Log into the ILOM web interface as Administrator (root) to open the web interface.

Select Maintenance --> Configuration Management.

Select a Reset Defaults value.

Click Save.

Modifying Console Escape Characters

This section describes creating new character combinations for use as escape characters.

To Change Console Escape Characters Using the CLI

Use the /SP/console escapechars property to change the escape character sequence to switch from a system console session back to ILOM.

Type:
-> set /SP/console escapechars=x.
where xx are any printable characters.

The sequence is limited to two characters. The second character is always . (Period). The default value is #. (Hash-Period). The sequence can be customized.

Note - Changing the escape character does not take effect in a currently active console session.

Changing Configuration Policy Settings

This section describes managing configuration system policies using ILOM.

To Specify Backup of the User Database Using the CLI

The /SP/policy BACKUP_USER_DATA property specifies whether the local user database on ILOM (that is, user, password, and permission information) should be backed up. When this property is set to enable, this data is backed up on the removable system configuration card (SCC PROM) on the system.

Type:
-> set /SP/policy BACKUP_USER_DATA=value
where the value can be one of the following:
- enabled – Backs up the user database to the SCC (This is the default value).
- disabled – No backup.
  
  For example, if you want the local user database on ILOM to be backed up, type the following command:
  -> set /SP/policy BACKUP_USER_DATA=enabled

To Specify Host Power-On Policy Using the CLI

Use the /SP/policy HOST_LAST_POWER_STATE property to control the behavior of the server after an unexpected power outage. When external power is restored, the ILOM service processor starts to run automatically. Normally, the host power is not turned on until you use ILOM to turn it on.

ILOM records the current power state of the server in non-volatile storage. If the HOST_LAST_POWER_STATE policy is enabled, ILOM can restore the host to the previous power state. This policy is useful in the event of a power failure, or if you physically move the server to a different location.

For example, if the host server is running when power is lost and the /SP/policy HOST_LAST_POWER_STATE property is set to disabled, the host server remains off when power is restored. If the /SP/policy HOST_LAST_POWER_STATE property is set to enabled, the host server restarts when the power is restored.

At the -> prompt, type the following command:
-> set /SP/policy HOST_LAST_POWER_STATE=enabled
where the value for this property can be one of the following:
- enabled – When power is restored, returns the server to the state it was in before the power was removed.
- disabled – Keeps the server off when power is applied.
If you enable this property, you must configure /SP/policy HOST_POWER_ON_DELAY as well. For further information, see To Disable or Re-Enable Power On Delay Using the CLI

To Disable or Re-Enable Power On Delay Using the CLI

Use the /SP/policy HOST_POWER_ON_DELAY property to cause the server to wait for a short time before powering on automatically. The delay is a random interval of one to five seconds. Delaying the server poweron helps minimize current surges on the main power source. This poweron delay is important when multiple servers in racks power on after a power outage.

This property takes effect only if /SP/policy HOST_LAST_POWER_STATE is set to enabled.

Type:

-> set /SP/policy HOST_POWER_ON_DELAY=value

where value can be enabled or disabled (default).

To Manage Configuration Policy Settings Using the Web Interface

Log into the ILOM web interface as Administrator (root) to open the web interface.

Select Configuration --> Policy.

Click the Policy radio button of the policy you want to change.

Select an Action value to apply the Action (enable or disable) you have chosen.

Displaying Power Management Metrics

This section describes using ILOM to view the server’s power metrics. Topics include:

To View Power Management Properties Using the CLI

Type:

-> show /SP/powermgmt

For example,

-> show /SP/powermgmt 
 
    /SP/powermgmt
        Targets:
 
        Properties:
            actual_power = 280
            permitted_power = (none)
            available_power = (none)
            control = local
            policy = performance
            regulated_budget = (none)
            elastic_budget = (none)
 
   Commands:
        cd
        set
        show

where

actual_power displays the input power (in watts) consumed by all power supplies in the system.
available_power displays the input power capacity (in watts) that is available to system components.
permitted_power displays the maximum power consumption (in watts) expected.

To View the Total Power Consumed By the System

The value of /SYS/VPS is equivalent to the value of /SP/powermgmt actual_power.
