Hi Folks,
I have an intermittently noisy SAS drive, only at idle, and I cannot for the life of me work out what the cause is. My system is an HP Z420, LSI 9212 SAS controller and a Seagate SS33000650SS SAS drive (there are more SSD and SATA drives, but the Seagate is the noisy one). It came from a server recycling company, along with 4 others, all of which are fine, but in another system (Microserver Gen 8 with P222 RAID controller, although in all fairness they don't have time to be idle). The drive works fine, has no SMART issues, and is everything I need it to be, except silent at idle.
The noise is like a head seek, but it happens 5 or 6 times a second, and is there over 90% of the time. and each occurrence of the sound is almost identical. What I mean there is that it is not doing a random seek (assuming if it is a seek), it's doing (almost) the same seek each time. There are many reports of the head parking sound that happens during power management idle_b state, but I've turned off all power management, and I still get it. it is independent of all other hardware, as it happens even when just powered up with no data connection. all I have to do is access the drive and the sound stops. If I set it to do a sequential read, it stays silent the whole time, but as soon as the read finishes, it starts the noise again.
I have bought and used literally hundreds of SAS drives in the past (possibly thousands), but I have never put one in a workstation before, so it may be the this is normal for a SAS drive. anyone have any ideas if this is normal, or ideas about how to make it go away?
(sort-of edit: after i finished the above paragraph, it fell silent, and I went out for 2 hours. an hour after getting home., it's not made a sound).
TIA
