Issue with mini-SaS to eSATA to USB 3.0 setup

Issue with mini-SaS to eSATA to USB 3.0 setup

Cc-ing the SCSI and USB storage list.

Folks, does the attached picture look like a sane setup?  I've never
used mini-SaS to eSATA adapter before, let alone with four eSATA to USB
3.0 adapters.

Do you lose only hard drive insertion events, or do you lose remove
events as well?

For example, what happens when you do this:

1. Unplug the eSATA to USB adapters from the USB 3.0 hub.
2. Insert a hard drive into the bay.
3. Connect the eSATA to USB adapter to the USB 3.0 hub.
4. Wait for hard drive detection, then hot-remove the drive from the
bay.

It looks like you're only attaching one eSATA to USB adapter to the
roothub.  Do you only have one USB 3.0 port on the host, or can you try
plugging in multiple eSATA to USB adapters into the roothub?

Does the setup work when only one eSATA to USB adapter is plugged into
the USB 3.0 hub?

> Do you have any suggestions?

A couple possible root causes come to mind:

1. Perhaps the USB 3.0 hub is interfering with communication to your
eSATA to USB 3.0 adapters.

2. Maybe USB device suspend is to blame.  Do you have USB device suspend
enabled for the eSATA to USB adapters?

3. Perhaps the SATA adapters aren't responding with a Medium Changed
status when the USB storage device is plugged in.

Can you send me dmesg, starting from just before you insert a hard drive
into the drive bays?  I need dmesg for both when the SATA adapter is
connected directly to the roothub, and when it's connected to the USB
3.0 hub.

A usbmon trace might also be useful for the USB storage developers.
Documentation on how to take that trace is here:

Re: [usb-storage] Issue with mini-SaS to eSATA to USB 3.0 setup

[Matthew Dharm]

I highly doubt hot-insert and hot-remove of HDDs from the 4-bay
container (without removing the corresponding USB/eSATA adaptor) will
work.

The USB/eSATA adaptor does not have a way to inform the host that the
eSATA side has been disconnected from the HDD.  That functionality
isn't in the usb-storage protocol.

This type of functionality *might* be supported in the UAS protocol,
but I don't know.

Well SAS to eSATA is okay (works for me: LSI SAS9212-4i4e HBA
via a SATA to eSATA cable to a SATA disk caddy with an eSATA
port).

eSATA to USB 3.0 adapters sound pretty dodgy, especially when
no mention is made of UAS(P).

This seems to be all just SATA signalling, no SAS involved at all, just
the physical shape of the connector is miniSAS.

It is disabled by default.  I just wanted to make sure an installed udev
script wasn't enabling auto-suspend.

You can check whether auto-suspend is enabled by running powertop and
looking for the lines that correspond to the USB 3.0 to eSATA adapters.
If they say 'Bad', device suspend is disabled.  If they say 'Good',
device suspend is enabled.

Or you can find the power/control entries for the devices in
/sys/bus/usb/devices/ and make sure they say 'on' rather than 'auto'.

It loses both events, randomly.

I am not sure, I thought it was disabled by default. How can I check?

Subject: Re: [usb-storage] Issue with mini-SaS to eSATA to USB 3.0 setup

Thanks for your reply, Matt.

But it works! Only sometimes the OS doesnt "see" hot-insertion /
hot-remove. And if I connect the USB/eSata directly to PC (without the
USB 3.0 hub), it works 100%, never miss an insertion/removal!

I have created some UDEV mounting rules, and they work fine, no mather
in which bay the HDD has been inserted. The problem is that sometimes
it can not recognize a hot-insert (which is not a big problem, the
user just has to remove/insert it again). But the major problem occurs
when it cannot detect a hot-removal, because the device stays mounted,
partitions still appear at /proc/partitions, etc. as if the HDD was
still there.
