Sun Microsystems 6800/4810/4800/3800 manual Do not use DR

Caution –While upgrading the firmware, heed the following precautions:

-Read the README and Install.info files before you upgrade the firmware.

-Do not change the keyswitch position of any domain.

-Do not use DR.

-Do not power off any boards.

-Do not reboot the system controller.

If you upgrade the scapp or rtos images for status:

1.It is important to watch the console during the flashupdate procedure.

2.Monitor the console if errors are reported.

If the images that are already installed are incompatible with the new images:

1.Shut down the domains before performing the firmware upgrade.

2.After you perform the firmware upgrade, reboot the domains.

If the images that are already installed are compatible with the new images:

1.Reboot the domains after performing the flashupdate procedure. Even though the firmware is compatible with the older firmware version, you must upgrade the firmware to obtain new features and bug fixes.

If you install a replacement board into the system:

1.Check if the firmware level of the replacement board is the same as the board you replaced.

2.If is it not, perform the flashupdate procedure on the board.

Caution –Under normal circumstances, the flashupdate command will complete successfully. However, if the flashupdate command is terminated abnormally (such as a power failure, a failed network connection, and so on), the system controller goes into maintenance mode.

To bring the system controller out of maintenance mode and back into its normal operating mode, type the flashupdate command with a valid URL or use the reboot command to boot the system controller with an older firmware version.
