Default Hard disk standby / spin down

Hi.

I am looking for a working solution for the hard disk standby / spin down problem: if I set the standby timer with "atactl sd0 setstandby 120", then the disk goes to standby. But after an access, the standby timer does not work.

Is there no way to "turn off" the disks after a period of inactivity?

Best regards
Sabbel

Please provide the entire output of dmesg(8).

Describing the behavior you are experiencing as the "hard drive standby/spin down problem" is vague at best. The output of dmesg(8) will give readers information as to platform, OS version, & the kernel's interpretation of the system's hardware. This is useful information to those who may be able to provide assistance.

If I submit the command "atactl sd0 setstandby 120", the disk spins down after a few seconds. But after I access the disk, they spin up, and never spins down.

I have no idea where the problem lies...

OpenBSD deals with both SATA & USB devices as SCSI devices. This is why you see the attached storage as sd0 & sd1 (See the sd(4) manpage for more information.) in the dmesg(8) output. The atactl(8) manpage states that it manipulates IDE devices (See wd(4)). This would account why you are not getting the desired behavior with sd(4) devices.

But the command works with SATA drives (the first call), only after "waking up" the disc dont switch to standby.

Your hard drive is the Samsung HD204UI. This may or may not be applicable to your situation but there is a known problem with the drive and its handling of S.M.A.R.T. commands issued by programs such as atactl(8).

Samsung has a firmware fix for the HD204UI and a firmware fix for the HD204UI/JP variant.

My apologies. I had not digested enough of the atactl(8) manpage to see that SMART commands are being handled as well. My last comment about atactl(8) being wd(4) specific was in error.

The default atactl command is identify, and that is the command that can cause a data loss during a write, prompting the firmware updates.

I did find some comments about this rebadged Samsung/Seagate drive through Googling that lead me to believe that standby timing may be affected by apmset power management levels.

I've been wondering:

The # atactl sdo setstandby 120 command issues an ATA standby command, which per the ATA specification is supposed to place the drive in standby and set or disable the timer value. I wonder if Sabbel could force the drive to enter standby mode after a failure of the timer to do so, using the # atactl sd0 standby command, which issues standby immediate, a different ATA command to the drive.

Without the firmware update, issuing an ATA identify command should be safe when the drive is operationally unused (unmounted). I wonder if, after a failure to enter standby, if an # atactl sd0 (the default identify command) might show power management disabled or the power management level set to a range that prevents the drive from re-entering standby mode.

So, the tip with the firmware have make my day I have a few of HD204UI's, and one of them has the original firmware, the other ones have the updated firmware. The original firmware has problems with the standby / setidle.

Thanks to your support!

I'm glad the problem is resolved!

I'm particularly pleased that your dmesg lead me to a useful answer.
