Thank you for this posting – it helped me to replace fast one of my faulty SATA RAID disks on a running server.
Cheers

Have you checked your BIOS settings? SATA hotplug does not (usually) work until you set BIOS to use AHCI for the chipsets; on most motherboards it is set to ‘ide-emulation’ or such by default.

Very cool, thanks for sharing. Not sure why this hasn’t been implemented to happen automatically since eSATA with hotplug support has been around for a while now.

Great post dude! Was exactly what I was looking for though for the reverse reasons. I wanted a way to stop/hide the hard disk from the OS once it had loaded the live image in RAM, this was for a media centre I’m building.

Hello Nils,

Here are some hints to get you started :
1) here’s how to get the list of the attached disks : fdisk -l | grep ‘^/dev/sd’ | awk ‘{print $1}’
2) Do this at script start up, save result in a temp file
3) Run the command to discover new disks as described in the post
4) Get the disk list again. Is there a new disk (maybe use diff) ? Yes -> terminate. No -> sleep 10 sec and go to 3

Hope this helps ! (and hopefully I understood correctly what you need )

Hi St�phane,
thanks for sharing this.
If I would put the hotplug scan into a bash script, I would like to have the script wait, until “# fdsik -l” actually recognizes the newly added device / redo the scan until the device has been recognized.

Any ideas on how to do this?

Thanks, Nils
