Talk:How to hotswap Ultrabay devices

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.

bash script for hotswapping UltraBay

Here is my script for hotswapping ultrabay, is more complex, supports swap partition on drive in ultrabay and more :)

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 guarenteed 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.
