[[Plugin] Spin Down SAS Drives]

Only other suggestion I have is to set the timers in the disks. The disks should spin down after 9000 seconds.

 

sdparm --flexible -6 -l -S --set SZCT=9000  /dev/sdx number is per 100ms

sdparm --flexible -6 -l -S --set STANDBY_Z=1 /dev/sdx

Thank you, but this method has also been tried.

The hard drive SZCT is at least 60 minutes(36000), and I used sg_raw to force a timeout, but it didn't work. 

Of course, stanbyz has been set to 1 to enable it.

Okay. In general, this thread is for support of the plugin.

This is the infamous 04h/11h status.
When the issue happens, you may want to try
sg_start -rp1 /dev/sdX
and see if it helps.

There's no echo, and the hard drive doesn't spindown.

What controller are you using. Mine are LSI based and works fine with SEAGATE ST4000NM0023 Constellation ES.3 4TB 7200

LSI 3081 IT

I have tried a lot of methods, including the previous smartctl 7.2, but it didn't work all the time, so I decided to give up.

I plan to use them as cold backup disks.

Have you been using the SAS Spindown plugin?

No, my NAS os is Arch Linux.

have you tried 

 

sg_start -r --pc=3 /dev/sdx this will set to spin down without explicit requirement for a start.

It didn't work.

And I also tried "sg_raw /dev/sdd 1b 00 00 00 30 00", didn't work too.

"sg_start -S " and "sg_start -s" are valid.

My "Seagate Constellation ES ST32000444SS" needs NOTIFY (ENABLE SPINUP) to spinup , too.

I found that I  can use "sdparm_64.exe  --command=stop  PDx"  to spindown it,

and it can be automatically spinup by Win server 2019 when there is a disk request.

 

This scheme is feasible. I want to know if its mechanism can be transplanted to UnRAID?
