interruptions.

Using the CLI method
You must have root authority on the NAS Gateway 500 to update its firmware. This method allows
updating from files already loaded onto the NAS Gateway 500. Update with the file located in the
/tmp/fwupdate/ subdirectory. Enter the following commands:
cd /usr/lpp/diagnostics/bin
./update_flash -f /tmp/fwupdate/3R030718.img
Note: Do not overlook the periods (.) in the above command.
You will be asked for confirmation to proceed with the firmware update and the required reboot. If you
confirm, the NAS Gateway 500 automatically performs the update and reboots. The checkpoints 99FF and
99FD alternately appear while the update is in progress. This may take up to thirty minutes, depending on
the configuration of the system. Because the update occurs during this shutdown/reboot sequence, it is
important to protect the NAS Gateway 500 from interruptions.
To verify that the update was successful, the firmware level can be checked as described in “Determining
the level of firmware on the system” on page 285.
Recovery mode
If the service processor detects that its programming has been corrupted when it is powering on to
standby mode, it will enter recovery mode. In recovery mode, it prompts for the firmware update diskettes
by putting eight-digit codes on the operator panel, as shown in the following table. After the update
process is complete, the service processor resets itself and performs a complete reboot.
Code Action

A1FD 0002 Insert update diskette 2.
A1FD 0003 Insert update diskette 3.

Notes:
1. If the wrong diskette is inserted at any time, or if the diskette is left in the drive after it has been read,
B1FD 001F
is displayed, indicating that the wrong diskette is in the drive.
2. If B1FD 001A is displayed at any time during the process, the service processor must be reset by
activating the pinhole reset switch on the operator panel.
