Use this procedure to perform a slow boot by using the Hardware Management Console (HMC), control panel, or
Advanced System Management Interface (ASMI) menus depending on your
configuration.
In some cases, you need to perform a slow-mode boot to perform
extended diagnostic testing.
Note: A slow-mode boot might produce
a new reference code on the control panel or new errors in the service
processor error log. When the server reports a new error code, record
it for use in subsequent steps.
