Determining a hardware boot failure
During the hardware boot, you see progress messages, if the model has a front panel display. If the model does not have a front panel display, light path LEDs indicate a hardware boot failure.
Before you begin
Line 1 of the front panel displays the message Booting that is followed by the boot code. Line 2 of the display shows a boot progress indicator. If the boot code detects an error that makes it impossible to continue, Failed is displayed. You can use the code to isolate the fault.

About this task
If the boot detects a situation where it cannot continue, it fails. The cause might be that the software on the hard disk drive is missing or damaged. If possible, the boot sequence loads and starts the IBM Spectrum Virtualize™ software. Any faults that are detected are reported as a node error.
Perform the following steps to determine a boot failure:
Procedure
- Check that the placement of the DIMMs is correct. An incorrect DIMM configuration might prevent the node from booting.
- Attempt to restore the software by using the node rescue procedure.
- If node rescue fails, complete the actions that are described for any failing node-rescue code or procedure.
