System controllers may have significant loss of functionality such as: - System Inventory displays nothing. - System controller 1 is in Faulted state. - No Slot info in Partition default. - Lost connection to Controller Floating IP. - Admin account login becomes impossible.
System controller malfunction.
Faulty fantray or interrupted LOP firmware update may cause bootloader mode.
If caused by a faulty fantray, it should be removed or replaced to prevent the LOP from going into bootloader mode again. A power cycle can be used to restart the LOP and get it out of bootloader mode.
If a system controller's LOP is in bootloader mode during booting, the automatic firmware update process will recover it.
