resetting GSP

The Guardian Service Processor (GSP) reset command always returns the message: "GSP reset failed." This message is wrong; the reset might have succeeded. The error message is due to a delay introduced in GSP firmware. The driver does not wait for this delay and returns an error message to the stty command.

What To Do

To reset GSP, type:

stty +resetGSP < /dev/GSPdiag1

Ignore the message "GSP reset failed" and wait for approximately 30 seconds, then verify the GSP status.

Verify the status of the GSP with the following command:

stty +queryGSP < /dev/GSPdiag1
