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. |
Note - The BIOS is not upgraded by this emergency recovery procedure. Perform a 2nd ILOM-based flash upgrade, to update the BIOS version. |
Note - This emergency flash recovery procedure returns the SP to default configuration. |
5. Press F2 to enter system BIOS and verify that the flash device is in the boot order.
6. After a successful flash, remove the flash drive from the USB port.
Wait at least 2 minutes to let SP come up first.
8. Power on the server and enter BIOS.
9. Confirm following items are correct in BIOS:
a. BMC Firmware Revision is correct on the Main page.
b. Status of BMC is working in Advanced -> IPMI 2.0 Configuration page.
10. Exit BIOS and start the operating system.
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 (SW2 on the motherboard) sends a reset order to the processors, resetting the main system, but not the service processor. 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 NMI button is the center button of the row of 3 hidden (recessed) buttons on the back of the motherboard. 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 processors, 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 User's Guide.
