Summary: Fail to issue Start/Stop Unit
Product: IO/Storage
Version: 2.5
Kernel Version: 2.6.34-rc5
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: SCSI
AssignedTo: linux-scsi@vger.kernel.org
ReportedBy: ian@beware.dropbear.id.au
Regression: No
I am attempting to save power by spinning down idle scsi disks. These are old
fashioned parallel (U320) disks on a SCSI storage controller: LSI Logic /
Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07).
I do:
sg_start --stop /dev/sde
echo 0xfffffff > /sys/module/scsi_mod/parameters/scsi_logging_level
dd if=/dev/sde of=/dev/null count=1
sleep 10
echo 0 > /sys/module/scsi_mod/parameters/scsi_logging_level
I get:
dd: reading `/dev/sde': Input/output error
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.00536828 s, 0.0 kB/s
If I manually spin up the disk with sg_start --start /dev/sde, then things work
again as expected.
The relevant log is as follows:

There is a different design philosophy between SCSI and
ATA disks (and has been for a very long time) reflecting
their different markets. When a SCSI disk is spun down, then
it will return errors on any command trying to do IO
until a SCSI START STOP UNIT command (start) is sent and then
time is allowed for the disk to spin up.
What you report as a bug is the long standing behaviour of
SCSI disks which Linux has not tried to modify.

If you set the allow_restart sysfs parameter on the disk, it should automatically

Ah, thanks. That works perfectly!
I knew that traditionally this wasn't supported in linux (as per comment #1)
but I also understood that the functionality had been added in recent kernels.
In my defence, I can't find any reference to this in "man sd' nor with "grep
allow_restart Documentation/scsi/*".
Can this be treated as a documentation bug?
