Hi All,
I am trying to configure a ThinkPad T430 for hotswapping Ultrabay devices based on the instructions on ThinkWiki.[1] Everything is working smoothly except that the udev rule for running the Ultrabay eject script is not being fired when I unlock the bay lock latch.[2] I'm wondering if this is expected behavior (because the latch is purely physical) or if it's a software/firmware issue. Has anyone had any luck getting this to work on recent ThinkPads? Troubleshooting Information: - The T430 has a Serial Ultrabay Enhanced bay. - I'm running an unpatched Linus 4.3 kernel under Debian testing. - Nothing is printed by acpi_listen when unlocking the bay lock latch. - Nothing is printed by evtest on the "ThinkPad Extra Buttons" input device (with hotkey_mask set to hotkey_all_mask) when unlocking the bay lock latch. - The DSDT contains references to the following Eject Request events: Notify (\_SB.PCI0.LPC.EC.BAT1, 0x03) // Eject Request Notify (\_SB.PCI0.SAT1.PRT1, 0x03) // Eject Request Notify (\_SB.PCI0.SAT1.SCND.MSTR, 0x03) // Eject Request Recommendations? Is there an event that I can listen for, or should I just run the ultrabay_eject script manually? Is there a way to trigger Ultrabay eject from desktop environments? (It looks like udisks support for Ultrabay device removal has been stalled for years[3] so perhaps not?) Any thoughts/recommendations are appreciated!

Please have a look here: https://github.com/wmlive/ultrabay-scripts Ready made packages for Debian can be fetched from here: http://wmlive.rumbero.org/repo/ I would like to hear back from Ubuntu users if these packages also work for them.

Thanks for taking the time to maintain and package these scripts. Have you considered/attempted to get the package into the official repositories? It would be great to see it more widely available. If I may make one suggestion: I'd prefer tp-smapi-dkms as a Recommends rather than Depends, since it's not useful on the T430 and so that I don't have to install dkms and kernel headers which I'm not using. But otherwise the packaging and repository worked very well. After playing with the scripts a bit, I'm still not having any luck getting an automatic undock and I'm a bit confused about how the scripts are supposed to work. It looks like the udev rules listen for ENV{EVENT}=="undock", KERNEL=="dock.1", ACTION=="change", SUBSYSTEM=="platform", ATTR{type}=="ata_bay" rather than ENV{BAY_EVENT}=="3", ACTION=="change", SUBSYSTEM=="scsi" My understanding was that BAY_EVENT 0x3 is EJECT_REQUEST (user request, via switch/button) while the undock event is fired once the device has been removed from the dock, at which point it is too late to unmount filesystems and prepare for undocking. In testing it just now, it appears that the undock event is fired in response to # echo 1 > /sys/devices/platform/dock.1/undock at which point the drive is disconnected. So it appears to be necessary to call ultrabay_eject to initiate the undocking, but then why would it be called again as a RUN script? Perhaps I'm confused? However, I did find this rule to be instructive: SUBSYSTEMS=="block", DEVPATH=="/devices/pci0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0", ENV{UDISKS_SYSTEM_INTERNAL}="0" Unfortunately, it looks like support for the UDISKS_SYSTEM_INTERNAL property was removed in udisks 1.90 and later.[1] I can't find any discussion about the reason, and the original bug[2] was not reopened, so I'm not sure how to interpret it. Thanks again for your efforts on making this less painful, they are appreciated!

While I used to be an official Debian package maintainer in a former life, it would need someone else to contribute an official package. I maintain my own Debian spin named 'Window Maker Live' and, as time permits, i am currently trying to separate out all the scripts i once wrote for it as separate projects and packages.
