Drive activity LEDs on CSE-M35T

Do these LEDs light with all disk? So far I haven't seen any LED lit.

Mine do.

Mine do.

Do you use the CSE-M35T cage, If yes which disks? Is it disk-dependant whether the activity LEDs light up?

Mine light up green when a drive is accessed but there's no LED for just being "on"

Culd you say which disks you use?

I have some older Samsungs in it, and no lights at all. Also just datacable from an M1015 and powercable hooked up to the cage

Mine do like Warheads, light up when there is activity.  I have used Hitachi 2TB, Samsung 1TB, Seagate 1.5TB and HP SAS 146GB SAS drives. All work the same way.

Some older drives don't send the right signals for the led to work. Some new seagates send the wrong signal so the led reverses (if multi colored)

The new seagate do have a firmware fix. As far as older drives. I have no issue with any sata2 or sata3 drive. I have tried several models. Never tried a sata1 model.

The fail light won't work without a compatible raid card and an alarm cable connected.

I have a test server with two drives (parity and data) that are both installed in a CSE-M35T cage.  Running unRAID 5.0-rc6-r8168-test2

Parity = Seagate ST3000DM001-9YN166, type = SATA 3.0, firmware = CC46

Data = Seagate ST2000DL003-9VT166, type =  SATA 3.0, firmware = CC3C

The data drive LED functions properly (green with activity, dark (non-lit) with no-activity), however the parity drive LED is constantly green.  The unRAID web interface (main tab) indicates the parity drive is spun down however the LED is constantly green.  I'm going to see if I can determine if the LED goes dark with activity (reversed condition mentioned above).  Do you think the parity drive might need a firmware update to properly function with the CSE-M35T cage LED?

to fix your Seagate ST3000DM001-9YN166_W1F067ZV, type = SATA 3.0, firmware = CC46

you need to update your FW to CC4H which you can download from seagate

Thank you onehunghig!  Upgrading the Seagate ST3000DM001-9YN166 drive firmware to CC4H solved the LED problem! 

I have 3 disks inside a CSE-M35T and those lights just flash on/off ever 1-2 seconds. With no SATA cables attached at the moment. The other thwo are out with a disk inside. Is that normal behaviour?
