23.15Update Process Status and Logging

During the update process, status is sent to stdout as it executes. Output will also be appended to the file /usr/local/cmm/temp/update/update.log. This file will be copied to /etc/cmm/update.log at the completion of the update process.

Status output will be of the format:

MM/DD/YY HH:MM:SS [process[pid]]: [Message String]

23.16Update Process Sensor and SEL Events

Once the CMM enters the update mode in which no CMM processes are active, events cannot be entered into the SEL directly. While in this mode, the CMM will enter events into the EEPROM. Once the system reboots into the OS, the CMM will log the events from the EEPROM into the SEL.

23.17Redboot* Update Process

The firmware can also be updated through Redboot. This update is done at a pre-OS level, meaning that the update is executed before the OS loads. This method requires updating over TFTP through the eth0 Ethernet port and must be done locally.

Because this process can completely erase the flash and operates in a pre-OS environment, it can be used as a failsafe to recover from failed firmware updates done from the command line interface.

Use the following instructions to perform a firmware update using this method, but please also refer to any instructions included in the update package and in the Specification Update for additional information.

23.17.1Required Setup

To update the flash on the CMM using the Redboot* method, the following setup is required:

1.A host computer running Microsoft* Windows XP, 2000 or NT4.0 operating systems

2.The above computer should be configured with a static IP address of 192.168.100.20 and a subnet mask of 255.255.255.0 if connected directly or on the same subnet as the CMM.

3.It is highly recommended that the subnet be isolated. The only two network entities on the subnet should be the CMM and the Windows computer.

4.If the update is to be run over a live network, an unused IP address on the network will be needed.

5.The host computer should be connected via serial port to the console port on the CMM to monitor the update process as it occurs.
