Rescuing a Server Using the CELLBOOT USB Flash Drive

Caution:

Follow the rescue procedure with care to avoid data loss.

To rescue a server using the CELLBOOT USB flash drive:

  1. Connect to the Oracle ILOM service processor (SP) of the rescued server. You can use either HTTPS or SSH.
  2. Start the server. As soon as you see the splash screen, press any key on the keyboard. The splash screen is visible for only 5 seconds.
  3. In the displayed list of boot options, select the last option, CELL_USB_BOOT_CELLBOOT_usb_in_rescue_mode, and press Enter.
  4. Select the rescue option, and proceed with the rescue.
  5. At the end of the first phase of the rescue, choose the option to enter the shell. Do not restart the system
  6. Log in to the shell using the rescue root password.
  7. Use the reboot command from the shell.
  8. Press F8 as the server restarts and before the splash screen appears. Pressing F8 accesses the boot device selection menu.
  9. Select the RAID controller as the boot device. This causes the server to boot from the hard disks.

Note:

Additional options might be available that allow you to enter a rescue mode Linux login shell with limited functionality. Then you can log in to the shell as the root user with the password supplied by Oracle Support Services, and manually run additional diagnostics and repairs on the server. For complete details, contact your Oracle Support Services representative.
