{0} ok boot
FATAL: /pci@7c0/pci@0/pci@1/pci@0/usb@6: OpenBoot initialization sequence prema.

FATAL: system is not bootable, boot command is disabled

When powered off/on via ALOM or power button the error is not reported.

Cause

Apparently due to conflicting pre existing ldom configuration.

Solution

Reset the SC bootmode config to factory-defaults and then reload the OS.

Command Usage:

sc> bootmode config="factory-default"
sc> poweroff

Wait for system to power off.

sc> poweron -c
OR
sc> poweron
