Firmware to spin-down HDD? [Archive] - AsusForum.NET -- WL500g

scuby

After days of messing, i've finally got my WL-500gP doing pretty much what I want. However, the one remaining annoyance is that the USB hard drive won't spin down, and to remove it I need to login to the web interface just to say "eject"... which isn't particularly helpful.

So, i'm looking for a new firmware with that implemented. I'm currently using the standard Asus FW and happy enough with that - i need to keep the ability for it to operate as a router (share the WAN connection with several wifi devices), to share a printer, to share a hard drive, and for a wired network device to be on the network too. Other than that, i'll happily lose all the other features.

Are there any firmwares out there that can do that, and that are suitable for a linux-novice (i've played a teeny bit with Linux, and can get a friend to explain bits of it over the phone, but not experienced myself).

I have read around this and other forums about the problem, and it does seem to be possible, but I can't do anything with the standard firmware, and the most common Oleg one doesn't seem to include sharing the USB drive. Also, I only have a laptop so can't directly connect the drive to an IDE interface to change the HDPARAM settings.

Any suggestions very gratefully received! :)

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):

./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.

Thanks a lot for that.

Is it possible to do that on the standard firmware, or will I need Oleg's (or similar) to do it? I'm a little apprehensive to put the Oleg firmware on as the documentation suggests it doesn't support the USB hard drives.

Well, this is definitely untrue.

I noticed I couldn't telnet into the box with the standard firmware, how would I go about putting that file on it, and your script?

Cheers

David
I don't know whether my solution can work with standard firmware. I really don't think so. I recommend you to replace it.
I didn't said that the most appropriate place for scsi-stop and scsi-stop.sh is in the router's flash so you should place it somewhere in /usr/local and then do:

flashfs save
flashfs commit
flashfs enable

I don't think that this feature is implemented in the Asus firmware.

I am impressed that someone finally managed to find a way to spin down HDDs. I understand that Oleg was the hero (again).
Because I did not know of this solution at the time, I have bought an Western Digital MyBook Essential 250GB. This drive spins down by itself.

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?

hi Xander,

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

Tutorial. :)

If you want to spindown your external HDD, scsi-stop (http://oleg.wl500g.info/bin/scsi-stop) tool may help you. This tool is a part of scsi-idle (http://lost-habit.com/scsi.html) 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,

regarding to USB enclosures with Cypress chipset, there might be a chance with following command:

/usr/local/sbin/scsi-start 0 --pc=2 /dev/scsi/host0/bus0/target0/lun0/disc

if someone has the knowledge how to program USB access, there is a special feature in the Cypress chips to pass-through ATA commands. Details are in the AT2LP rev C datasheet (http://download.cypress.com.edgesuite.net/design_resources/datasheets/contents/cy7c68300c_8.pdf) might be only a few lines of code for a pro....

also the chip has a register for setting autom. spindown value on ATA-initialisation, but I never got it to work....

I did some experimenting:

using my pc (ubuntu feisty fawn), I was not able to spin down the harddisk with the scsi-tools either (just as under kamikaze on a wl-500gP).

the lsusb output of the external HD is:
ID 04b4:6830 Cypress Semiconductor Corp. USB-2.0 IDE Adapter

Using the sg3-utils of ubuntu (http://sg.torque.net/sg/sg3_utils.html)
i did manage to make the disk spin down (but it didn't spin up until
after a reset of the drive)

I'm now trying to make a package out of it, but haven't finished yet.

tuigje

26-05-2007, 13:02

I just made an package, but sadly, it doesn´t work.

on my (ubuntu 7.04) pc, it works as expected:

sg_start --stop --pc=2 /dev/sda

On my wl-500gP however, it doesn´t:

sg_start --stop --pc=2 /dev/discs/disc1/disc
start stop unit: pass through os error: Invalid argument
START STOP UNIT command failed

I used the exact same source for both the PC and the WL-500G, both are statically build versions, so that´s not the difference.
On http://sg.torque.net/sg/sg3_utils.html it is noted that for kernel 2.4 the /dev/sg0 interface is required. It can be made with

mknod /dev/sg0 c 21 0
But I haven´t yet figured out how to enable the support in the kernel for /dev/sgX.
I can mount and read the disk, so scsi support itself is working fine.

I´m running kamikaze with 2.4 kernel (for wifi support) Is there anyone interested in testing this for kernel 2.6 ?
Both the makefile and (compressed) .ipk file are attached.

Where is your Swap located? on the HDD?
The system often reads swap data.

For me the best solution was to read all program data and swap from an usb-stick and all the other data from the hdd.

13-06-2007, 09:54

@britnet:

swap and opt on an usb stick? How long is this active until now? Any problems with the flash memory producing errors? Is it USB v1 or v2? What about performance?

background: This were my first thoughts for the WL-HDD. But i didnt do it because of USB 1.1 and the limited rw cycles of flash chips.

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 &

:confused: 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. :D

I have tried to put it into post-boot, but nasty things happened when i tried to do it, my router couldn't get an IP at all after i've inserted this line into post-boot.

./scsi-stop.sh /dev/scsi/host0/bus0/target0/lun0/disc &
My router was working perfectly before with samba and print sharing going on.

At the end, i had to use the recovery mode of the router to flash the firmware again. For I had completely lost the router, it's not getting an IP (I had IP reserved for it), not replying to ping, completely blocked out from me.

Now I had everything running again, but I am afraid to put that line into post-boot again. I fear I might brick the router if i do.

Would the router support usb hubs? I want to have a usb memory stick to act as a swap memory for the router so that the HDD can stay quiet at night time.
Right now I have a printer plugged in and a HDD, it would be nice if i can put a hub in and attach the USB memory stick as well.

Edit: I have put that line of code into post-boot after the first attempt (disaster), it didn't crash this time. So I must have done something really wrong back then.
This is what I put in that works

/usr/local/sbin/scsi-stop.sh /dev/scsi/host0/bus0/target0/lun0/disc &
To view how you can see if the process is running in the background, type

ps | grep scsi

This is strange, could you please post the VendorID and ProductID of your device. (lsusb or cat /proc/bus/usb/devices)
According to this (http://wl500g.info/showpost.php?p=52360&postcount=20) table your device should work if the GUID corresponds to the VID and PID.

Okay, I just bought a 3,5''-Case which is not working (.. it was even already posted here: GUID: 05e307020000000000000000)

But unfortunately in the list here, there a no prices or type names. I would like a cheap one - so can one recommend sth?
this (http://www.pollin.de/shop/shop.php?cf=detail.php&pg=Nw==&a=MjE3ODcyOTk=) one would be really cheap - but which chipset in it?

so, it was actually quite easy.

Here´s a small patch to kamikaze, which selects the generic
scsi driver as well.
The ipkg packge (for kamikaze 2.4) is included as well.

Use this patch to make the scsi-kmod module, then do a

mknod /dev/sg0 c 21 0
mknod /dev/sg1 c 21 1
insmod sg

to make the devices and load the driver. Using:

sg_start -s -p 2 /dev/sg1

you can now spin down a scsi device. The scsi-start utility still doesn´t
work for me though.

How can I install "scsi.patch"?
I tried to install "kmod-scsi-core_2.4.34-brcm-1_mipsel.ipk" in your "scsi.tgz" and then I got an error message: ...md5sum mismatch...!
How can I countinue? Thanks

MMm, I wouldn't know were ipkg gets the md5sum from. the md5sum
in the Makefile is correct, i just checked that.

Building from source should work. I'm now running a 2.6 kernel, that
already has proper scsi support, that might work
for you also (but 2.6 still no wireless AP-mode for the wl500g).

Kamikaze brcm47xx kernel 2.6 on Asus WL-500gP

USB -> SATA adapter is a very cheap one, but based on Sunplus:

Quirks:

# cat /proc/bus/usb/devices
Vendor=04fc ProdID=0c25 Rev= 1.12
Manufacturer=Sunplus Technology Co.,Ltd.

So from all I can read it should be working, but when I run scsi-stop I get:

# /scsi-stop /dev/sda
/dev/sda is not a SCSI block device
or a different program I found here: http://www.johnkerry.plus.com/scsi-spin.html which should be compiled for Kamikaze (no version mentioned) and kernel 2.6:

# scsi-spin -d -f /dev/sda
scsi-spin [warning]: device is mounted but --force is passed
scsi-spin: /dev/sda is not a disk or generic SCSI device.

Anybody have any ideea why it is not working?

I'm a total Linux newbie but still I managed to spin down my HDD with scsi-stop. I also put scsi-stop.sh script in my router according to instruction provided here. However two questions come to my mind.
Is this instruction full or do I have to do something more to get this script running every time I reboot my router?
I read here that it is impossible to spin-down HDD when Samba is running. Is it true? I am using my HDD as a media disk so everyone in the house can acces it. That is why I don't want to use the switch on the enclosure to power off/on my drive (it won't be accessible). I want it to be accessible all the time but to spin-down in periods of inactivity (e.g. when everone is at work, at night) to extend life of the disk and not to make noise in the night. I use Samba to share disk in Windows.
As I'm new to Asus's router and Linux any help will be apreciated.

I found the following deamon:

Spindown is a system daemon that spins down idle disks [...] uses sg_start to spin the disk down. It also works with usb disks and hotswappable disks because it doesn't watch the device name (hda, sdb, ...), but the device id. This means that it doesn't matter if the disk is swapped while the deamon is running.

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?

Hi, I'm actually using teddy_bear's USB Tomato mod (http://www.linksysinfo.org/forums/showthread.php?t=60185) 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.

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.

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

PERIOD=30
BOUNDARY=1200

SCSISTART=scsi-start

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

while true; do

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:

/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 )

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

i get:

/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 !

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

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:)

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

yes that was helpfull. THANK YOU

But i have a problem when i run your script, my command line freezes and i have to exit with ctrl+c and hdd won't stop spinning. how can i test this ?

and by the way thank you very much for your help !

[admin@RouterASSUS root]$ /usr/sbin/scsi-stop /dev/sda
/dev/sda is not a SCSI block device

by the way my firmware is not oleg's latest .10 , is 1.9.2.7-rtn-r3497 as i said . hdd seems that doesn't work via scsi mode or something is changed ....

quoting:

this can be used like:

/usr/local/sbin/scsi-stop.sh sda &
/usr/local/sbin/scsi-stop.sh sdb &

don't forget the & character, it will make the script run in the background;)

by the way my firmware is not oleg's latest .10 , is 1.9.2.7-rtn-r3497 as i said . hdd seems that doesn't work via scsi mode or something is changed ....
I know I use this script on my rt-n16.
if it says "/dev/sda is not a SCSI block device" it might not be possible.
it did work on .10/d firmware for you?

04-01-2012, 11:43

adn yes: ........

[admin@RouterASSUS root]$ ls /dev/ | grep sd
sda
sda1
sda2
sda3

but

[admin@RouterASSUS root]$ /usr/sbin/scsi-stop /dev/sda
/dev/sda is not a SCSI block device

Yes you'r right it was the & symbol.

in .10 firmware didn't work ( so i thought) because my hdd wasn't supported. but i didn't have those errors. is an another way to stop my hdd ? thanks for your support !

hmmm yes, the .10 firmware trick is the same as this one... just the script to check the activity is different. so then you should probably use the sdparm version rumenchooo uses.
if that doesn't work either... no idea:p

"ctrl+c"

[admin@RouterASSUS root]$

what is wrong ?

PS i switched hdd disk name from sdd to sda. and i saw running mc that i do not have an /date directory on /opt/bin.

tmsulica

04-01-2012, 17:55

but one more question wpte ... on .10 firmware existed path /dev/scsi/host0/bus0/target0/lun0/disc

now in this build with what is replaced ?

because /dev/sda is not an SCSI block device, so on this build where is the scsi block device ??

10x

Hey tmsulica ,

so you have one HDD (sda)?

Try this one.

1.Check the paths/location of your programs

/opt/bin/sdparm
/opt/bin/sync
/opt/bin/sg_start
etc..

are they correct for you??

2.Did you install sdparm and sg3-utils??

3.Put this line in /opt/etc/crontab:
*/10 * * * * admin /opt/whatever-you-want/that_script
It will check fo activity every 10 min.

4.Are the commands worked for you by himself????
sdparm --flexible --command=stop /dev/sda &>/dev/null
sdparm --flexible --command=sync /dev/sda &>/dev/null
sg_start 0 --pc=2 /dev/sda
awk '/sda/ {print $12}' /proc/diskstats
etc.....

But even if you succeed , the disk will not remain down , because firmware need to access it.(log , swap ... etc)!!!
Even cron need to read that script from HDD!!!
So spin up again ->> spin down --> spin up --> spin down.
And that is for VERY short periond.
As you know HDD don`t like spin up/donw too much.

You have to install /opt on the flash stick and use HDD only for storage.

#!/bin/bash
DISKNAME=sda
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 [ $a == 0 ]
then
echo "$DISKNAME 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/$DISKNAME
else
echo "$DISKNAME Active-->wait ....." >> /opt/var/log/syslog.log
fi
exit 0
