Flash disaster recovery

To successfully recover an Onboard Administrator from a failed flash, you must have the following:

  • Local access to the enclosure
  • A DHCP server accessible by the Onboard Administrator
  • A TFTP server accessible by the Onboard Administrator
  • Onboard Administrator firmware (.bin file)

To recover from a failed flash use one of the following processes:

  • If you have only one Onboard Administrator in the enclosure or you want to Flash Recover the Active OA:
    1. With a null-modem cable (9600 N, 8, 1, VT100), locally connect to the Onboard Administrator.
    2. Press and hold the Reset button of the Onboard Administrator for 5 seconds.
    3. On the serial console, when you are prompted for Flash Recovery or Reset Password, press F. The Onboard Administrator obtains an IP address through DHCP.
    4. At the prompt for the TFTP server IP address (where the Onboard Administrator image files are stored), enter the appropriate IP address.
    5. You are prompted for the path to the Onboard Administrator firmware image. The Onboard Administrator downloads the image and flashes itself.

Upon successful completion of this process, the Onboard Administrator firmware is up to date, and any error condition is repaired.

  • If you have two Onboard Administrator modules in the enclosure and you want to Flash Recover the Active OA:
    1. With a null-modem cable (9600 N, 8, 1, VT100), locally connect to the Onboard Administrator.
    2. Press and hold the Reset button of the Onboard Administrator for 5 seconds.
    3. On the serial console, when you are prompted for Flash Recovery or Reset Password, do not type anything. Wait at least 2 minutes or more to let the Standby OA to become the Active OA before proceeding to the next step.
    4. When the OA to be flashed has become the Standby OA, press and hold the Reset button a second time on the same OA as in step b.
    5. On the serial console, when you are prompted for Flash Recovery or Reset Password, press F. The Onboard Administrator obtains an IP address through DHCP.
    6. At the prompt for the TFTP server IP address (where the Onboard Administrator image files are stored), enter the appropriate IP address.
    7. You are prompted for the path to the Onboard Administrator firmware image. The Onboard Administrator downloads the image and flashes itself.

Upon successful completion of this process, the Onboard Administrator firmware is up to date, and any error condition is repaired.
