Recent Ubuntu versions
I think, it must be mentioned that hotswapping Ultrabay devices using recent distros is by far not that hard as before. I'm using Ubuntu 9.04 on Z61m and in my case hotswapping Ultrabay DVD-RW works out-of-the-box without any scripts or whatsoever. The article however suggests that one always needs some ejecting scripts which might confuse certain users. So it would be nice to add something like: "If you are using Ubuntu *.** everything should work out-of-the-box"
--Bombenbach 12:01, 9 August 2009 (UTC)
Really? Did you try to swap out a Ultrabay device with mounted filesystem? Good luck! The udev handler and eject script are there for a reason. By default no action is taken when you pull out a device, which can cause real problems if not handled properly.
--Tonko 09:31, 10 August 2009 (UTC)
Well, actually I couldn't imagine that someone would like to pull out an Ultrabay device with mounted file system. As far a usb flash drives are concerned, you won't do that either, right? My point was, that if the file system is properly unmounted, I can simply pull my Ultrabay DVD-RW out without any freezes or crashes. And when I put it back again, the drive is automatically recognized by Ubuntu so that I can use it. I don't have an Ultrabay HDD, but I assume that if it works with DVD-RW it also should work with HDD. Correct me if I'm wrong. If the sole purpose of eject script is hotswapping Ultrabay devices with mounted filesystem then I still think that it would be nice to point it out in the article.
--Bombenbach 07:52, 11 August 2009 (UTC)
By default on most modern distributions based on a recent kernel with libata, the libata driver gets to cleanup the mess after the fact, if you pull out an ultrabay device without first
- unmounting the filesystem
- powering down the device
You may be lucky, or you might end up with a hung system, corrupted filesystem, etc. Your choice.
There is work going on upstream to resolve this with DeviceKit-disks, but that depends on a patch to the Linux kernel, which has not made it in yet, since right now there is no correlation between the udev event and the actual Bay device, and since you can have multiple Bay devices (in fact your ThinkPad likely has 3) this correlation is needed, otherwise DeviceKit-disks would need to know about every single Laptop out there and the mapping between the Bay numbering and the actual devices (something the kernel can easily just provide instead).
Here is a Feature request against DeviceKit-disks that provides some status information http://bugs.freedesktop.org/show_bug.cgi?id=23110

HAL script
If the script works, your lshal output should contain something similar to this. In this case the Ultrabay device was a second HDD (/dev/sdb).
Note that in the example, storage.hotpluggable = true while before it was false, so the script worked.
udi = '/org/freedesktop/Hal/devices/storage_serial_SATA_HTS726060M9AT00_MRH453M4H11ARB' block.device = '/dev/sdb' (string) block.is_volume = false (bool) block.major = 8 (0x8) (int) block.minor = 16 (0x10) (int) block.storage_device = '/org/freedesktop/Hal/devices/storage_serial_SATA_HTS726060M9AT00_MRH453M4H11ARB' (string) info.capabilities = {'storage', 'block'} (string list) info.category = 'storage' (string) info.parent = '/org/freedesktop/Hal/devices/pci_8086_24ca_scsi_host_0_scsi_device_lun0' (string) info.product = 'HTS726060M9AT00' (string) info.udi = '/org/freedesktop/Hal/devices/storage_serial_SATA_HTS726060M9AT00_MRH453M4H11ARB' (string) info.vendor = 'ATA' (string) linux.hotplug_type = 3 (0x3) (int) linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1f.1/host1/target1:0:0/1:0:0:0/block/sdb' (string) storage.automount_enabled_hint = true (bool) storage.bus = 'pci' (string) storage.drive_type = 'disk' (string) storage.firmware_version = 'MH4O' (string) storage.hotpluggable = true (bool) storage.lun = 0 (0x0) (int) storage.media_check_enabled = false (bool) storage.model = 'HTS726060M9AT00' (string) storage.no_partitions_hint = false (bool) storage.originating_device = '/org/freedesktop/Hal/devices/computer' (string) storage.partitioning_scheme = 'mbr' (string) storage.removable = false (bool) storage.removable.media_available = true (bool) storage.removable.media_size = 60011642880 (0xdf8f90000) (uint64) storage.requires_eject = false (bool) storage.serial = 'SATA_HTS726060M9AT00_MRH453M4H11ARB' (string) storage.size = 60011642880 (0xdf8f90000) (uint64) storage.vendor = 'ATA' (string)

lshal output
Please place your lshal output here if you had problems
lshal of my A31: http://nopaste.org/p/a4p6x9tSob
Thanks! If I understand the output correctly you have one Toshiba Combo DVD-ROM/CD-RW R2002 in one ultrabay connected as slave to the primary IDE controller, and one Toshiba DVD-ROM C2512 in the second ultrabay connected as master to the secondary IDE controller. Can you confirm? I have added it to the table.
I have a Thinkpad T43 and I found out from my lshal output that I had to use parent device:
pci_8086_2653_scsi_host_0_scsi_device_lun0 instead of
pci_8086_2653_scsi_host_scsi_device_lun0 (notice the added 0).
This is the ultrabay, however, the internal disk still use the "original" parent device (the one without the 0).
I think this information should be added to the table.
Specs:
Thinkpad T43 (machine type 2668),
Mandriva One 2009.1,
haldaemon 0.5.12
Thanks, it is possible that you have AHCI mode disabled in the BIOS for your HDD?

comments
Interesting, especially the support for swap partitions. but I have two comments, first your calling your script hotswap.sh and then having udev call ultrabay.sh?
Then your hard coding the location of the Ultrabay device. This is not guaranteed to be correct, although it will be in most cases. In particular the A and W-series machines. A-series had support for more then one Ultrabay device, while W-series has support for more then one internal HDD in addition to the Ultrabay device, so the Ultrabay location will shift. That is why the Ultrabay Eject script on the main page gets the eject device information from udev.
comments
Hi, thanks, I fix name of script :) Udev calling ultrabay.sh with option -d, so it remove correct device, if you want remove device manualy, is default device useful. But option may be required...
more comments ;)
You might also have a look at the script on the main page, it has a few extra abilities, such as logging to syslog, beeping and putting up popups on the desktop.
Logging to syslog is simple, just call 'logger' with what you want to log. quite should have no effect on this.
For beeps, similar to what windows does you can echo different values to /proc/acpi/ibm/beep, but it only works if sound is not muted. Unfortunately doing so does seem to generate some annoying messages in syslog.
Lastly you can use notify-send to put up messages on the desktop, but before you can do so you have to do an export DISPLADISPLAY=0:0 /usr/bin/knotify4 --passive-popup : Adresář nebo soubor neexistujeY=:0.0
Syslog and beep
OK, scrip now support syslog and beeping :).
Still missing notify-send ;)
I am also thinking that it would be useful in the case of a busy filesystem to tell the user to run something like fuser -mv /dev/sr0
Or perhaps we should run it ourselves automatically and just tell the user what is the cause of the busy filesystem.
