If the SP (service processor) software becomes corrupted, you can reinstall the default SP software image from the Tools and Drivers CD.
This emergency flash recovery procedure returns the SP to a default configuration.
The ILOM SPBIOS <file-name>.pkg file format (for example ilom.X4150-2.0.2.6.pkg) cannot be used for emergency recovery. Use the <file-name>.bin recovery image instead.
1. Copy the following SP files from the Tools and Drivers CD, located in the recovery directory, to a USB bootable flash device.
2. Insert the bootable flash drive into the USB port.
a. Press F8 to get a list of the boot devices.
b. Choose the USB flash boot device.

socflash -p 1 -f <sp-binary-file> -b <backup-binary-file>
socflash -p 1 -f g12n.bin -b ilombak.bin
Note - If you choose to back up the SP binary (-b <backup-filename>), you must ensure there is sufficient free space on the USB flash device to hold the backup file. |
Note - Use the command socflash -h to get a complete option listing. |
4. After a successful flash, perform an AC power cycle or reset the SP using the following command:
Note - Using -r (resetting the SP hardware) can cause the VGA display to become disrupted. |

Caution - Do not use the Reset and NMI Dump switches unless you are instructed to do so by a Field Service engineer. |
The Reset switch on the motherboard sends a reset order to the CPUs, resetting the main system, but not the service processor. The button for this switch is one of the 3 hidden (recessed) buttons on the back of the motherboard located between the NET MGT and NET0 connectors and closest to NET0. It can be pushed by sticking a paper clip or similar object through the hole provided on the rear of the chassis.
The NMI button is the center button of the row of 3 hidden (recessed) buttons on the back of the motherboardlocated between the NET MGT and NET0 connectors. The button for this switch can be pushed by sticking a paper clip or similar object through the hole provided on the rear of the chassis.
The Non-Maskable Interrupt (NMI) Dump switch sends an NMI order to the CPUs, which is used by Field Service for debugging activities at the request of operating system engineers. NMI can also be asserted by ILOM. Refer to the Sun Integrated Lights Out Manager 2.0 User's Guide.
