Firmware to spin-down HDD?

**AshDyk** · 13-05-2009, 22:16

I would really like to spin down my HDD when it is inactive for 20 minutes. When I try

PHP Code:


 /usr/local/sbin/scsi-stop /dev/scsi/host0/bus0/target0/lun

0/disc

, I get this error:

PHP Code:


/dev/scsi/host0/bus0/target0/lun0/disc is not a SCSI block device

Am I doing something wrong, or does it just not work with my HDD. If it doesn't work, are there any other options?

I'm using two 1tb discs in RAID1 (using mdadm) and mounted as md0

Code:

$ cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid5] [multipath]
read_ahead 1024 sectors
md0 : active raid1 scsi/host0/bus0/target0/lun0/part1[0] scsi/host1/bus0/target0/lun0/part1[1]
      976759936 blocks [2/2] [UU]

if I use the scsi-stop script (one for each disc) the discs spindown correctly but when the discs are needed again only one disc resume, breaking the RAID sync. Is there a way to stop this from happen or another script to use raid md0?

Code:

scsi-stop.sh /dev/scsi/host0/bus0/target0/lun0/disc
scsi-stop.sh /dev/scsi/host1/bus0/target0/lun0/disc

the discs:

Code:

$ cat /proc/scsi/usb-storage-0/0

Hi, I'm actually using teddy_bear's USB Tomato mod on a WL-520GU (stupid 4 MB flash...), and it includes scsi-stop and scsi-start, and I wanted to share my experience with getting it working.

I used a watt-meter to verify that the disk actually did spin down or up. My setup involves an external enclosure with the following stats.

Code:

   Host scsi0: usb-storage
       Vendor: JMicron
      Product: JM20336 SATA, USB Combo
Serial Number: DA0150217888
     Protocol: Transparent SCSI
    Transport: Bulk
         GUID: 152d23360000da0150217888
     Attached: Yes
         Port: 1
          Bus: 00:03.1-1

Vendor=152d ProdID=2336

This is very similar to one that doesn't work (PID=2338). But I had to do something funny to get mine to work. If I call scsi-stop, the disk spins down, and when I go to access it, the disk becomes inaccessible. If I call scsi-stop and then scsi-start before accessing the disk, it behaves correctly, staying spun down until I go to access it.

There are other Tomato-specific requirements for scsi-stop and scsi-start. You need to put the script in /jffs, and you need the build with awk. Here's the final script with the other Tomato-specific changes.

Code:

#!/bin/sh
if /usr/bin/[ $# -ne 1 ]; then
        /bin/echo 1>&2 "Usage: $0 <device>"
        exit 1
fi

PERIOD=30
BOUNDARY=1200
SCSISTOP=scsi-stop
SCSISTART=scsi-start
LOGFILE=/tmp/scsi-stop.log

searchstr="disk_io:"
devaddr="(`/bin/ls -l $1 | /usr/bin/awk '{print($5 int($6/16))}'`)"

str=`/bin/grep "$searchstr" /proc/stat | devaddr="$devaddr" /usr/bin/awk -v 'RS= |\n' -F : '{ if($1==ENVIRON["devaddr"]) print($2) }'`
cooltime=0
stopped=0

while true; do
        /bin/sleep $PERIOD
        newstr=`/bin/grep "$searchstr" /proc/stat | devaddr="$devaddr" /usr/bin/awk -v 'RS= |\n' -F : '{ if($1==ENVIRON["devaddr"]) print($2) }'`
        if /usr/bin/[ "$newstr" = "$str" ]; then
                cooltime=$(($cooltime + $PERIOD))
                if /usr/bin/[ $cooltime -ge $BOUNDARY -a $stopped -eq 0 ]; then
                        $SCSISTOP $1
                        $SCSISTART $1
                        time=`/bin/date '+%b %e %H:%M:%S'`
                        /bin/echo "$time: Cooled down..." >> $LOGFILE
                        stopped=1
                fi
        else
                if /usr/bin/[ $cooltime -ne 0 ]; then
                        time=`/bin/date '+%b %e %H:%M:%S'`
                        /bin/echo "$time: Disk first used after $cooltime seconds" >> $LOGFILE
                fi
                cooltime=0
                str=$newstr
                stopped=0
        fi
done

My problem was firmware 1.9.2.7-d-r1612, with oleg 1.9.2.10 was everything ok.
Problem was only my swap (its on the same hdd).
Disc goes down, but after second it spin-up

so nothing for me

Hy , i have a question for you guys:

How can i stop my HDD from spinning when i don't need it ?

I read this post: http://wl500g.info/showthread.php?t=7836&page=5 and i tryied xander solution:

Here's the possible solution:
1. Download http://oleg.wl500g.info/bin/scsi-stop - this binary is able to spin-down your disk immediately after execution.
2. Place it somewhere on your router (you should be able to reach it via PATH environment variable) and make it executable.
3. You can use the script I've written which works in background and spins down disk after some period of inactivity:
http://wl500g.info/showpost.php?p=47135&postcount=10
I use it this way (I named the script scsi-stop.sh):

Code:
./scsi-stop.sh /dev/scsi/host0/bus0/target0/lun0/disc &It automatically writes some log messages to scsi-stop.log.
It works for me. You can change it as you wish.

but seems that my hdd doesn't work through scsi mode because i get:

Code:

/dev/scsi/host0/bus0/target0/lun0/disc: No such file or directory

and when i try the path that i think is correct ( newbie, i know )

Code:

[admin@RouterASSUS work]$ scsi-stop /dev/discs/disca/disc

i get:

Code:

/dev/discs/disca/disc is not a SCSI block device

I have latest 1.9.2.7-rtn-r3497 firmware from http://wl500g.googlecode.com/, and installed by wengi tutorial from: http://wl500g.info/showthread.php?t=10307 (with disca changes of course)

Can anybody help ? Thank you !

Hi ,

you can modify that script for you needs ,plase it somwhere and make a cron job:
It looks ugly , but worked for me.

#!/bin/bash
DISKNAME=sdd
now=`/opt/bin/date`
a=0
#check 70 times with 0.1s gaps,
#and go on adding
for i in `seq 0 70`
do
b=`awk '/$DISKNAME/ {print $12}' /proc/diskstats`
a=`expr $a + $b`
sleep 0.1s
done
echo $a
if [ $a == 0 ]
then
echo "$now /dev/sdd No Activity-->>spindown" >> /opt/var/log/syslog.log
/opt/bin/sync
/opt/bin/sdparm --flexible --command=sync /dev/$DISKNAME &>/dev/null
/opt/bin/sdparm --flexible --command=stop /dev/$DISKNAME &>/dev/null
/opt/bin/sdparm --flexible --command=stop /dev/$DISKNAME &>/dev/null
/opt/bin/sg_start --stop /dev/$DISKNAME
/opt/bin/sg_start --stop /dev/$DISKNAME
/opt/bin/sg_start 0 --pc=2 /dev/$DISKNAME
/opt/bin/sg_start 0 --pc=2 /dev/$DISKNAME
/opt/bin/sg_start 0 --pc=3 /dev/$DISKNAME
/opt/bin/sg_start 0 --pc=3 /dev/$DISKNAME
else
echo "$now /dev/sdd Active-->wait ....." >> /opt/var/log/syslog.log
fi
exit 0

Of cours you have to :
ipkg install sg3-utils
ipkg install sdparm

Regards
Rumen

thanks a lot, but how can i test it before because doesn't work on all hhd's ?

And btw what do i put in crontab ? what line, or can i put the script in init.d ?
And second, disk name i have to put my disk name ? and the time for waiting to idle is editable ? thank you very much!

PS: when i try a simple command

[admin@RouterASSUS root]$ /opt/bin/sg_start --stop /dev/discs/disca

i get

Error trying to open /dev/discs/disca: Is a directory

even when i enter:
[admin@RouterASSUS root]$ /opt/bin/sg_start --stop /dev/$DISKNAME

i get:

Error trying to open /dev/: Is a directory

I used the old scsi tools to do the same thing: http://wpte.kicks-ass.net/forum/showthread.php?tid=4
it's a modification of the old d script

**tmsulica** · 04-01-2012, 11:06

hy, that is what i was looking for, but can i issue a command before all this to see if the hdd is stopping ? like in the old scsi-stop ?

2. that is my problem i can't find hdd name .......

well the harddrives are labeled like "sdx" with x as a or b or c etc.
so your first drive is called "sda" your first partition on sda is called "sda1" etc.
you can check it in /dev :

ls /dev/ | grep sd

for me it shows this:

sda
sda1
sda2
sda3
sdb
sdb1

you can try if the script will work like this:

/usr/sbin/scsi-stop /dev/sda
