Firmware to spin-down HDD?

[britnet]

hi Xander,

great that you managed it!!!

I'm using your script and it works really nice.

Can you write a complete HOW-TO for the beginners?

Well, Ok, I'll write it soon. I must tell everybody that this binary is not working with several hard drives. This was reported in the similar topic in the Russian forum.
Oleg said also that this tool is a part of scsi-idle package, so you can compile it yourself. Just grab sources here: http://lost-habit.com/scsi.html

Hi,
is possible to use this for wl-500gx too?
But I will wait for tutorial to beginners

[greengreen]

HI Xander
something new about the tutorial of spining-down disc?
Can you write here which kind of disc isn't suported?(My knowledges of Russia language are nothing )

THX very much

[Xander]

Tutorial.

If you want to spindown your external HDD, scsi-stop tool may help you. This tool is a part of scsi-idle package. If you don't want to build the tool from sources, just use the first link to get a prebuilt binary provided by Oleg.

Since you want to spindown your disk it is not very sensible to place the binary on it. So the appropriate place is the router's flash.

Steps:
1.

cd /usr/local/sbin
wget http://oleg.wl500g.info/bin/scsi-stop
chmod a+x scsi-stop

2. Now you can test your disk for compatibility. Please, ensure your login shell is /bin/sh and you run scsi-stop in it. cat /etc/passwd will help you to find out.

/usr/local/sbin/scsi-stop /dev/scsi/host0/bus0/target0/lun0/disc

If your disk continues to spin then scsi-stop most likely doesn't support your ide->usb (or sata->usb) box.
Please, post your results and your hardware here. Let other people know whether it is supported or not. And please add the output of

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

and search for corresponding VendorID&ProductID in the output of

cat /proc/bus/usb/devices

3. If you were successful you maybe would want to use my script for automatic spindown:

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

PERIOD=30
BOUNDARY=1200
SCSISTOP=/usr/local/sbin/scsi-stop
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 /bin/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 $1
                        time=`/bin/date '+%b %e %H:%M:%S'`
                        /bin/echo "$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

You can change "period" and "boundary" variables. They are in seconds. With the current settings script will wake up every 30 seconds to gather information and after 20 minutes of inactivity it will stop disk.
Do:

cd /usr/local/sbin
cat > scsi-stop.sh
<copy and paste the script>
<press Ctrl-C>
chmod a+x scsi-stop.sh

To run script in background do, for example:

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

Notice that the script writes some log messages to /tmp/scsi-stop.log .

4. Don't forget to do

flashfs save
flashfs commit
flashfs enable

to save all the things in the router's flash.

Hi All,

Xander, thanks for the great tutorial! Worked perfectly. My results:

I was actually surprised that such a cheap/generic HDD box would support HDD idling!

Thanks,

As stated; my box doesn't work.
Inside a Hitachi Travelstar, which might be spindown by itself, according to another topic...

Tutorial.

3. If you were successful you maybe would want to use my script for automatic spindown:

PERIOD=30
BOUNDARY=1200
SCSISTOP=/usr/local/sbin/scsi-stop
LOGFILE=/tmp/scsi-stop.log

Do:

cd /usr/local/sbin
cat > scsi-stop.sh
<copy and paste the script>
<press Ctrl-C>
chmod a+x scsi-stop.sh

To run script in background do, for example:

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

I'm a little confused. I created the scsi-stop.sh script and executed the command.

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

Now, how do I ensure this works properly after rebooting? Should I place this line:

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

into my post-boot file?

And how do I spin the drive up again? Or does a user just have to try accessing a directory via SAMBA?

Thanks.

[hkfriends]

when SAMBA is running, the box can not spin down.

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

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

, I get this error:

/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?

[s1za]

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

$ 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?

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

the discs:
