Information in this document applies to any platform.
An Exalytics server was restarted after planned reboot. System will now not boot up. The Service Processor (SP) light comes on but then the [OK] light flashes and a console window cannot be rendered. When the machine boots it may start the boot sequence and get stuck at "loading grub" or run through a boot sequence like:
2) PXE 1
3) PXE 2
4) PXE 3
5) PXE 4
Checking NVRAM ....
It may then get stuck at the "Checking NVRAM..." and then starts the boot process all over again without ever successfully rebooting.
In these cases, no keyboard, or user input option is available and the machine never fully boots.
This problem may occur on Exalytics bare metal or Exalytics Oracle Virtual Machine (OVM) servers.
