SAS Drive Firmware Update

[peace-keeping-villa8590]

I have 11 MZILS3T8HCJM SAS SSD's that I have been working with @limetech to figure out why these drives read/write at only ~50MB/s. If I attached the same drives to a Windows VM, they perform at ~900+MB/s read/write. It seems it's some sort of kernal/driver issue that even Unraid V7 doesn't support. I also have two more drives that look identical to the 11 others except that they are a different model number, MZILT3T8HBLS that seem to be compatible with Unraids kernal. These two drives perform much better at 800+MB/s natively. These two drives are NETAPP branded drives with firmware versions NA01 and NA03. My question is, is it possible to flash my other drives to the NETAPP firmware or a different, compatible with Unraids kernal firmware?

I would start by updating the firmware to NA04, these drives had a nasty bug that when they hit a certain power on hours they brick themselves.

Serverthehome has resources for this, I've had to do a few of these drives.

 

Not sure about the speed issues, although I've seen one isolated comment mention they don't always handle 6Gbps connections correctly... not sure if there is much weight in that one but worth investigating, maybe an incompatibility with controllers assuming you changed during your tests.

I was not aware of this and it good to know. I didn't mention it in my OP but I have searched around extensively for the process to update firmware (the update tool and firmware itself) but I cant find either on this drive. I presume you have done this firmware update?

tools are already on unraid, it just needs sg_write_buffer
You'll have to search, maybe ask around on servethehome forums, the firmware repo I've used in the past has been removed.

I believe I found the firmware on STH (FMDELMZILS3T8HCJMCQPJ_NS). I put this file in "/mnt/zfs/temp" cd'd to the directory and excited "sg_write_buffer -m dmc_offs_save -I FMDELMZILS3T8HCJMCQPJ_NS.bin /dev/sg14". Nothing happened. I presume that the new firmware is "QPJ" but smartctl -i /dev/sg14 shows no change from before and after. I rebooted the server and also added ".bin" to the file name with no luck. Do I need to physically remove the drive for a full power cycle?

I read on the STH forums that FMDELMZILS3T8HCJMCQPJ_NS could have multiple files inside? Am I supposed extract the folder to get the firmware inside?
