Online Firmware Update Procedure
Updating firmware online consists of three steps:
1. Checking the firmware status
2. Updating any firmware that is out-of-date
3. Checking the firmware status again to make sure that all of the firmware is up-to-
date
You can perform all three steps using TSM, which is described in the TSM
Configuration and Management Guide. An overview of TSM is provided in Section 7,
“Tools for Online Change.
Considerations for Updating Firmware
The following list describes considerations and limitations you should be aware of when
updating firmware online:
You should update firmware only when the system is relatively quiet and it is highly
unlikely that the update operation might be interrupted. (Interruptions can be caused
by a loss of power, a channel kill, a reset, and so forth.) An unsuccessful update
operation may leave a checksum error in the boot code, making the controller or
device inoperable and requiring a board replacement.
When updating controller firmware, you may need to take down all paths to the
controller before performing the update operation.
When updating processor firmware, read the product softdoc to determine if any of
the included microcode and millicode files have changed. If any of the files
included with the firmware have changed, you must reload the processor.
