Hardware: Silicon Image 3124 PCI card in computer connected eSATA to an
external drive enclosure with a Silicon Image 3726 port multiplier chip with
5 removable drive trays (http://high-rely.com/HR3/includes/HighRely/5BayMT/5BayMT.php)
containing 5 various hard drives.
To create the problem I simply turn off a drive bay and wait for it to be removed
from the system. Then turn the drive bay back on and usually the drive will not
reconnect without several cycles of turning it off and on.
Note the drives always seem to come up fine on boot with the external drive bays
already powered on and if I power cycle the drive bays with the computer on and booted.
I have included info from kern.log below showing turning the bay on and off before and
after I patched the kernel. I first applied the patch from your previous email
and changed the second timing value to 1000 and that makes it work. It also works
if you leave the timing values alone and up the retries (i.e ATA_EH_PMP_LINK_TRIES) from
3 to 5. It seems to me the drives are taking a long (relatively) time to spin up and
either way all we are doing is giving it more time to spin up. Is there some way to
know it is spinning up and wait for that rather than just trying to reset the controller
over and over? Also I notice from the kernel log that the 'hotplugged' flag is only
set the first time it does the hard reset and is then cleared. If this didn't get
cleared it may work that way as well. All of this only fixes the problem until an
slower drive comes out.
>From the SMART info on the drives for the WD 3TB that fails the spin up value was 188 vs.
a Seagate 160GB that was 87. I believe these values are in milliseconds so we can see
that the drive that fails takes much longer to spin up.

kern.log tends to be too cluttered with extra timestamps. Can you
please use 'dmesg -c' after each phase of testing? printk timestamps
included there should be enough.

That's debouncing timing. It doesn't have much to do with spinning
up. Spinning up can take over ten seconds. PHY is usually ready well
under a sec once power is applied. The reason why libata stops
waiting during reset is because PHY flickers - it comes up and then
goes out again. libata EH already debounces to work around these
glitches but it seems this 'flickering' is larger scale than libata
parameters expect.
One suspicion I have is that the PSU in the enclosure isn't stable
enough to maintain PHY state while multiples drives are powering up.
If this is the case, PHYs may keep flickering well over a second which
libata doesn't expect them to. Beefing up the PSU (or using a second
PSU to power some of the harddrives) and see whether anything changes
would be a good way to test it.

The hotplugged timing is supposed to kick in only once after a hotplug
event as some PHYs tend to take longer time to lock on after hotplug
event.

That's more likely centisecs instead of millisecs. 8.7sec would be
about normal for regular drives. 18.8 isn't too far off for large
ones with more platters. The more important thing probably is that
the WD 3TB drive is likely to draw much more power than the smaller
one taxing the PSU in the enclosure which could have been designed to
have just enough power for more regular drives.

So if you bump the second timing value to 1000, it works without
retrying? Can you please post kernel log w/ that change?
Thanks.

I doubt it is a PSU issue for a couple of reasons: 1) all drives (5) are
detected properly if I power the unit (external hard drive box, not computer)
off and on, and 2) it fails the same way with only 1 drive in the unit.
I will, however, try to test with a larger power supply tomorrow.

No, bumping the second timing value to 1000 does not cause it to
work without retrying. Even bumping it up to 10000 does not work
without retries (only bumping to 10000 on the first hotplug reset).
Upping the number of retries to 5 without changing
any timing works (on the 4th try) and changing the second timing
value to 1000 without changing the number of retries works. It
works if we try long enough (i.e. enough times or longer each time).
Below are logs from hotplugging a Samsung 160GB and a WD 3TB drives
with a kernel with stock timing values but retries changed from 3
to 5 with only the one drive installed.

I see. Yeah, it doesn't seem to be PHY flickering. It looks like
IDENTIFY is failing before disk finishes spinning up, which isn't the
correct behavior. SRST is supposed to wait for disk spin up
completion. I don't know why sil24 softreset is failing without
waiting for spinup. I'll see whether I can reproduce the problem
here.
Thank you.

I played with it a bit but couldn't reproduce the problem; however,
PMP EH does lack per-device retry back-off. On host ports, when
reset/identification fails for whatever reason, retry is backed off
such that even if controller/device interaction is faulty during spin
up, EH always retries after sufficient time is given to the device.
With PMP EH, this logic is missing partly because PMP EH sometimes
already takes too long and partly because tracking the timestamps
seemed a bit complex during the initial implementation.
So, this definitely contributes to why PMP EH fails to work around the
misinteraction between the drive and port and should probably be
improved, but let's also find out why the controller isn't waiting for
the drive after issuing IDENTIFY. Can you please apply the following
patch, reproduce the problem and report the kernel log?
Thank you.

The controller is saying that it failed to transmit command FIS
because PHYRDY state changed, so that is PHY flickering. Can you
please bump the second debounce timing to 1000 (not only the first one
but always) and see whether the failure pattern changes?
Thanks.

So, no change. Weird. I think we need to implement retry backoff
properly anyways but am still wondering why probing failure behaves
differently for you. I'll try with similar drive but maybe it's
difference in PMP firmware?
Thanks.

Tejun:
Here are the specs on the port multiplier board:
Lycom ST-126RM (http://www.lycom.com.tw/)
Sil3726 chip revision 17
EEPROM FW Version: 1.0114
Also there is another problem: ports that are not connected at power on
are ignored until a port that was connected at power on is hotplugged. So,
for instance, if I turn the unit on with only a drive on the first port, the
other four ports will not work and I don't even see kernel messages when
hotplugging until I hotplug the first port. I haven't looked into this yet,
but it would seem the driver must be disabling the ports and they are not
looked at again until the hard reset is performed.
Let me know if I can help in any way.
Thanks,

That's most likely the sil pmp itself. It has been known to show
erratic behavior if the first port is not occupied during power up. I
don't know whether later firmware updates fixed that tho. Can you get
hold of a marvell PMP and see how it behaves?
Thanks.

That may well be a problem, but is not the problem in this case since it
is not limited to port 0. Seems like the sil driver or pmp code in the kernel
is disabling the ports that are not connected at pmp power on and not looking
at them again until we hotplug one of the ports that was connected and cause
a hard reset or something like that.
For instance, I turn off the pmp unit and connect drives to
ports 0, 1, and 2 then power on the unit. Linux sees the pmp unit and finds the
three drives. Then I connect a drive to port 3 and Linux reports nothing. No
interrupts, no nothing. Same with port 4. However if I connect a drive to
port 3 or 4 (or both) and hotplug the a drive on any of ports 0, 1, or 2 now
the drives are detected after the hard reset.
This hardware works fine under Windows, hotplugging drives and powering the
unit off and on, etc. using the same Sil3124 eSATA PCI controller. No problems,
so I think the hardware is okay.
I don't know of nor have a Marvell PMP, but I do have another Sil3726
PMP board with newer firmware and a board with a JMicron PMP that I am
going to test with.
Thanks for your help.

I did some testing with a PMP board containing a Sil3726 with firmware
Version 1.0124 and a PMP/Raid board with a JMicron 393 configured as
PMP only. I am connecting to a Sil3124 esata pci controller.
The Sil3726 board acted the same as the previous Sil3726 board with the 1.0114
firmware.
The JMicron board worked much better. It works properly with a stock
kernel and does not fail the IDENTIFY after hotplugging and does
not require retries. It seems to wait for the drive to spin up before
doing anything so it works properly the first time without retries or
hard resets. The only problem I saw was that it seemed to not work at
all a couple of times if not powered up/connected before booting Linux.
Couldn't see it at all, even after several power cycles and unplugging/pluggin
esata cable. I need to test this more as it is inconsistent and may
have to do with the Sil3124 controller rather than the JMicron PMP.

Interesting, that's the behavior I see w/ my 3726 but all my PMPs are
very old, so I guess it has changed since then. A bit too lazy to
hook it up to windows machine to check firmware version ATM. :)

Like Derry who started this thread, I too had seen an old thread from
October/November 2008 with what appeared to be no resolution to this problem.
Now, finding this thread, again, with no apparent resolution to this problem.
I'm currently running Ubuntu 10.04 (lucid), kernel 2.6.32-33-generic. I've no
experience with applying these git patches, and my searching to figure out how
it works have not helped.
I'm using an Addonics eSATA PCI-X controller with the SiI3124 chipset, and I
have an Addonics PM in an external enclosure, with a 5 bay/tray DAS. Some of
my drives give me this problem: (this occurs for me with pretty much ALL
Samsung hard drives)

I've been using Ubuntu for a few years now, and have been living with the
problem...working around it with USB docking stations and such. But, I'd
really hope to see/find this problem worked out.
Thoughts/tips/suggestions? Since I'm pretty much a novice when it comes to
patching, a link to a guide for git patching would be appreciated too.
Thank You,
Mike

I think I know what is going on. One of your disks at least is slow to
spinup. Due to a bug/feature in silicon image disk controller and pmp,
at bring up we can not issue a SOFT_RESET and wait for the disk to
spinup and then continue.
That why we set ATA_LFLAG_NO_SRST in sata_pmp_quirks().
So what happen is we go into a function that issue identify, but we
fail, the disk is not ready [it is spinning up], so we retry.
3 times.
From the first hard reset: 12888.470385, to the time you got the final
error: 12901.397305 ~ 12.9s
In the second case, your controller can send SOFT_RESET and wait for
the device to respond.
Time for the disk to spinup:
28010.630028 - 27997.097116 ~ 13.5s
As you can see, you are borderline with the PMP, but the controller
did not "wait" enough in the first case.
Given the spinup time varies with drive, age, time since last
spin-up..., it may work one day and fail the next.
To work around the problem, I have a patch that consist of allowing
the silicon image control to send a reset, but if it fails, we spin
for a fixed amount of time and retry. This is not very nice, it is a
better design to wait for event that waiting a fixed amount of time.
You may have to alter ATA_LFLAG_WAIT_SRST to use the first bit available.
Can you try with the following patch?
Thanks,
Gwendal.

Allow controllers to send SOFT_RESET to Sil3726 PMP.
This PMP does not accept frames until the drive connected to
its port spins up.
Some controller [Sil3132 family] can not wait for the drive to spinup
and fails the reset, leading to unnecessary speed downgrade.
Not allowing to send SOFT_RESET can lead some drive slow to spinup
to be ignored and produces weird error messages.
This fix allows the error handler to wait if the controller is unable
to send a SOFT_RESET.

So, now libata waits for full reset period before proceeding to reset
PMP. Hmmm... yeah, it makes sense. Unfortunately, the only way to
achieve spinup wait in this case is waiting blindly and libata's reset
timeouts are configured to accomodate drive spinup times. PMP SCR
failure kinda destroys those blind wait periods.
I'm not too sure about ATA_LFLAG_WAIT_SRST. I don't think making the
new behavior default would hurt.
Can you please post before & after logs?
Thank you.

I am using 2.6.34. I try to have this mail follow the thread "RE:
Problem w/ hotplug on sata_sil24 w/ PMP (sil3726)", Derry started. It
did not work, sorry.
I will rebase the ata-dev branch soon - and clean up the patch
following Sergei comments.

Yes. Until the device sends the async D2H Reg FIS indicating the drive
spun up, the MPM does not accept the SoftRest FIS from the controller.
On most controller, that fine, the controller state machine keeps
retrying, but on Sil3132 it stops after a second or so and send an
error back to the driver.

Yes, I totally agree this blind wait is not clean. Normally we would
wait until an event occurs [async FIS] and have the timeout just for
the error case.
Here we wait [10s] because we think the device is spinning up.

I see your point. But if there is no PMP, Sil3132 is behaving, there
is no need of this logic.
>
> Can you please post before & after logs?
There are 2 problem with the current solution:
- by not waiting for device spin up, we basically disabled staggered
spinup: we send hard reset to all port very fast.
That may put burden on enclosure with weak power supplies.
- as Derry found out, disk which are slow to spin up can be ignored by
the kernel.
From my experience:

Yes but that's exactly how the reset timeouts are set up. They're
supposed to provide reasonable spinup timeouts when the proper wait
mechanisms can't do so and here it becomes a problem because the blind
timeouts are circumvented by SCR read failure handling.

Yes, sure, the behavior is necessary iff PMP is attached as that's
only time SCR read failure can occur anyway and I think it would
generally be a good idea to always enforce the blind timeouts if PMP
is attached, so no need for ATA_LFLAG_WAIT_SRST.

Looks pretty good to me. Nice spotting. Thanks a lot for tracking it
down and coming up with good solution. :)

Thank you...
Will this require a complete kernel recompile?
Or is there an easier way to include this patch?
I have little to no experience with working with patches at this level.
I've been doing research on how to use this patch, and I'm close, but, I'm not
sure if I need to attack compiling a kernel, or if I can somehow just patch
libata or something like that?
Thank you,
Mike

Thanks again for the help, but, I could use a little more instruction...
I've figured out how to apply the patch to the source, and compiled
the libata-pmp, and libata-eh modules(/drivers/ata), but, I cannot
figure out what to do from here.
The libata-pmp driver/module does not seem to be loaded on my system
to begin with...maybe this was part of my problem.

I wonder if this same logic is more generally applicable for PMP
rather than sil3132 specific? What I've read thus far in this thread
sounds very much like the issues I see here with PMPs not working
on JMB and Marvell controllers (where they USED to work fine).
Gwendal, have you got a version of that patch which applies the same
change globally rather than only for sil3132? I'd like to try it out here.
Thanks

By issuing SRST,
. We re enable staggered spin up
. We allow slow disks to spin up while we are still in initial error handler
However, some controller fails sending SRST while the disk is spinning up
behind the port multiplier.
To avoid slow disk to be ignored, or link to be downgraded unnecessarily, wait 10s if
SRST fails before resetting the ATA port.
With a Sil3132.

Reenable sending SRST to devices connected behind a Sil3726 PMP.
This allow staggered spinups and handles drives that spins up slowly.
While the drives spin up, the PMP will not accept SRST.
Most controller reissues the reset until the drive is ready, while
some [Sil3124] returns an error.
In ata_eh_error, wait 10s before reset the ATA port and try again.

While I agree with the change, the description doesn't seem too
accurate.

By issuing SRST,
. We re enable staggered spin up
. We allow slow disks to spin up while we are still in initial error handler
However, some controller fails sending SRST while the disk is spinning up
behind the port multiplier.
To avoid slow disk to be ignored, or link to be downgraded unnecessarily, wait 10s if
SRST fails before resetting the ATA port.
With a Sil3132.

Reenable sending SRST to devices connected behind a Sil3726 PMP.
This allow staggered spinups and handles drives that spins up slowly.
While the drives spin up, the PMP will not accept SRST.
Most controller reissues the reset until the drive is ready, while
some [Sil3124] returns an error.
In ata_eh_error, wait 10s before reset the ATA port and try again.

I just re-enable SRST for Sil3726, not the other PMPs. For the other
ones where ATA_LFLAG_NO_SRST is still set, we will not issue softreset
and therefore will not try to access the spining disk until we send
the first identify.
For the other PMP where SRST was allowed, I guess the Sil3132
controller would have offline the disks or downgrade the speed
unnecessarily.

Reenable sending SRST to devices connected behind a Sil3726 PMP.
This allow staggered spinups and handles drives that spins up slowly.
While the drives spin up, the PMP will not accept SRST.
Most controllers reissue the reset until the drive is ready, while
some [Sil3124] returns an error.
In ata_eh_error, wait for the next reset deadline before resetting the ATA
port and trying again.

I hope this can be applied to other controllers too as the failure
mode should be similar for all SIMG PMPs.
Thanks.

Maybe but I don't know. Spin up is usually waited upon by device
readiness wait after SRST which libata does every time it probes or
resets a device behind PMP. The drive is bringing link down briefly
after SRST is complete. It doesn't make much sense. Maybe some
quirkiness in the firmware?
Can you please try the attached patch? If it doesn't work, please
increment the constant 200LU by 100 each time and find out where it
starts to work.
Thanks.

You don't think it has something todo with the spin-up time?
The spin-up time on these disks is quite long:

I bought harddrive of the same generation but of lower capacity and
tested it with two 3726s but can't reproduce the problem you're

Can you please try the attached patch and see whether anything is

Hmmm... 2.6.24 works but 2.6.26 doesn't, strange. I've been trying to
reproduce the problem here but it doesn't happen with any drive I
have. I just ordered a similar drive, so I might have better luck
with it. I'll write back when I know more.
Thanks.

Hi,
I did installed an earlier kernel on the machine, and then hotplug
worked.
This is the log when I did hotplug using v2.6.24 (the kernel from Debian
Etch-n-half)
This is when I yank the drive:

It doesn't follow the drive. It sort of stays with port in that sense
that it happens on the first equipped port after the first one (which is
probed by the controllers BIOS). If I leave the second port empty, it
happens on the third when I do a cold boot.
I have also moved the drives around, and it does not follow the drive.
One odd thing that I've noticed is that it's only happening on my
Samsung drives, I've got a couple of WD aswell and they seem to work.

No, same behaviour.

I had to change it to:
ata_port_printk(ap, KERN_WARNING, "XXX error_intr irq_stat=0x%x\n", irq_stat);
I hope that was correct.
Yank the drive:

The drive seems to come alive and seems to start at [ 119.350834] above.
But then it's been tried 3 times and is already disabled.

Okay, that's enough. That means spinning up doesn't have anything to
do with the detection failure.

Can you please try the followings?
1. If you swap the drive on the second slot with another one, does the
detection problem stay with the port or follow the drive?
2. Does "libata.force=1.5Gbps" make any difference?
3. Apply the patch and post log after failed hotplug.
Thanks.

OK, The drives are placed in hotswap-cages in an external enclosure with
it's own powersupply. I have no possibility to connect the power to the
actual drive before signal when I'm hotswapping. I don't think that'll
make a difference though, since I have the same issue when I do a "cold
boot".
With "cold boot" I mean that I turn the power on the enclosure first and
then boot the PC. With a "warm boot" I reboot the PC a second time
without powercycling the disc enclosure or the discs.
When I boot the first drive on the PMP is detected by the Sil3124. If
it's a "cold boot", the second drive is not detected in Linux with the
same error as when I hotplug the drive.
When I "warm boot" everything detects and is fine until I hotplug a
disc.
Attached is dmesg from cold and warm boot, and hdparm -I on one of the
disks.
BR,

Hmmm.. drives usually make reset wait while they're spinning up so
that's where the spin wait logic is implemented. Strange. Can you
post full boot log and the result of "hdparm -I" on the drive? Also,
if you first spin up the drive by conneciting only the power connector
and then connect the SATA cable a bit later, does it work?
Thanks.

I've got trouble to get a drive to reconnect to the system after
hotplug.
I'm using Linux 2.6.26 (Debian 2.6.26-8) on AMD64. The controller card
is any Sil3124-based, and the disks are connected to a Sil3726.
The disks in this case (but I've got the same behaviour on different
disks) is SAMSUNG HD103UJ. Their Spin_Up_Time according to smartctl is
11030 (which I translate to approx 11 seconds, right?)
The disks are mounted in drivecages.
When I yank the disk this happens:
[75044.264218] ata4.03: exception Emask 0x10 SAct 0x0 SErr 0x4010000 action 0xf
[75044.264322] ata4: SError: { PHYRdyChg DevExch }

As I understand it, the first IDENTIFY happens 1 second after hotplug,
the second 5 seconds after hotplug, and the last and third one happens 9
seconds after the hotplug, and as I understand this disk need at least
11 seconds to spin-up.
The only way I can get the disk back online is to yank the cable between
the controller and the PMP, then it works.
Is it someway to extend the timeout to wait for spin-up of the disk?
Best Regards,
