Steps to Follow
Please validate that each troubleshooting step below is true for your environment. The steps will provide instructions or a link to a document, for validating the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.


Once a machine is configured with LDOMs, it can be reverted back to factory-default as described below.

There are 3 options available to reset the system configuration back to factory-default. Use any one of the steps below.

1. Setting factory default through LDOM Manager

To reset the configuration, use the set-spconfig ldm(1M) subcommand:

# /opt/SUNWldm/bin/ldm set-spconfig factory-default

Next, power cycle the system to for the new factory-default configuration to take effective.

Please refer to Section [2-A.] of Document: 1019467.1 for further details on resetting LDOM configuration using ldm(1M) command.

2. Setting factory default through Service Processor

The system configuration can also reset through the ALOM or ILOM prompt on the SC.

For machine with the ALOM on the Service Processor, use the following syntax:

sc> bootmode config="factory-default"
sc> poweroff

Verify system power off:

sc> showplatform

sc> poweron -c


For machine with ILOM, use the following syntax:

-> set /HOST/bootmode config="factory-default"
-> stop /SYS
Are you sure you want to stop /SYS (y/n)? y

Verify system power off:

-> show /SYS

-> start /SYS
Are you sure you want to start /SYS (y/n)? y
Starting /SYS
-> start /SP/console

This will have the configuration reset.

3. Setting factory-default via a Web Browser

Login to the SC via a Web Browser (network management must be configured in the SC).
Select the "Remote Control" tab
Select the "Host Boot Mode" Sub-tab

State: Normal
Script:
Modify the "LDOM Config:" field with "factory-default" (do not include the quotes)
Select Save

Please refer to Section [2-B] of Document: 1019467.1 for further details on resetting LDOM configuration through Service Processor.
