Default SP uBoot Tests

Startup diagnostics on the blade's service processor (SP) use the uBoot diagnostic utility. The following uBoot tests are executed whenever the SP is powered on or reset. If any of these tests fail, the blade will not start. See About Diagnostic Failures for additional information.
