Hi everyone, wondering if any of you might be able to help me debug some odd drive behavior.
I bought 6x3TB Seagate Constellation ES.2 drives from Bitdeals back in Feb and they just arrived yesterday (package lost in transit, and found). I plugged the 6 drives into my case (with some help from the discord since I had some mechanical alignment issues), and powered on to find that only 4 of the drives seem to be working. The 4 that work are working as expected, smart looks clean, I’m checking them more thoroughly now.
I can see that all drives are recognized by the system at plug, which implies that SAS communication seems to work since I can see the WWN and general data about the drives at that time. But then the 2 fishy ones try to spin up…and nothing. dmesg just stops reporting anything after attempting to spin the drive up (just a bunch of “.” lines that I assume are the system waiting). smartctl can’t reach them. I do hear them when they try to spin up, but I don’t get anything after that.
All 6 drives are connected to the same LSI SAS9210-8i HBA and they all use the same style of SAS cable (recommended here). I’ve tried swapping ports on the HBA, as well as swapping plugs that are physically connected to the SAS drives, all the same result.
I’ve tried unplugging other drives to lower power demands on the system just to be safe and no change either. Since all drives are the same model and use the same set of SAS cables/power supply/HBA I’m inclined to think that this isn’t a simple 3.3V power disable issue or a cabling issue.
Any ideas on what to try next?
