So i tried modifying a 01 00 00 00 to 01 00 02 20 based on this > webpage: > http://storagesecrets.org/2008/12/scsi-enclosure-services-ses-ses-2-management/ > > I also tried with 06 00 00 00 to 06 00 02 20, still nothing. > > I set the data using > sg_ses --control --page=2 -d - /dev/sg30 < raw.test So I don't really plan to parse a huge hex dump, but my instinct would be you got something wrong. I'd firstly validate that your lights can be flashed with the ses driver ... if they can, then look for a mistake in the hex dump.
