Talk:How to hotswap Ultrabay devices
Contents
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"

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.

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.
