Also thinking of getting another one, and see if I can get the Intel firmware to work on it. Unless anyone has already tried this?

UPDATE: Fixed it - stupidly, when I transferred the firmware over to the Ubuntu box (FTP), I did not set binary mode - did so, and all ok!

Hi Guys

No point in letting a good thread die, now is there!??!

Trying to flash one of these expanders and have sg_write_buffer fail. SG Version is 1.28 20180628.

Please see attached screenshot.flash.JPG

Anyone have and idea why?

Expander is on a 9201, and works fine. Zero drives attached to the 9201 or expander when trying to flash.

Using Ubuntu live.


Thanks in advance.

Thank you everyone for those great tutorials. Unfortunately my Linux live usb stick wasn't working as expected.
So, after digging around. I found the solution to update it in Windows(or PE)

1. Make sure driver for the HBA is working correctly in Windows.
2. Download sg3_utils for Windows port.
3. Open CMD as administrator
4. Get device id of the SAS Expander from running >sg_scan -b -s ( You will get something like SCSI2:0,8,0 for the actual device ID)
You can also find current firmware version here.
5. Run >sg_write_buffer --mode=14 --in=dl-634a.rd2 SCSI2:0,8,0
6. After completion, run again above cmd with mode=15 and without the --in
7. Rescan with sg_scan, you should see the new firmware version.

dmc_offs_defer = 0x0E =14
activate_mc = 0x0F = 15
