Replace drive without shutting down

[Adrian]

I have a Norco case. I have a slot reserved for where I preclear drives. After I preclear a drive, can I remove and put another drive in the slot without shutting down the server?

[JonathanM]

Yes, as long as the controller connected to that slot supports hot swap.

You will, however, have to stop the array. You should do that before removing a disk, and there would be no benefit from trying it with the array running since you can't assign the new disk with the array started anyway.

 

NVM, I see you weren't talking about an array disk

It's an LSI Logic SAS 9207-8i Storage Controller LSI00301

You can, before doing better to disable it, it also usually powers off the disk:

 

echo 1 > /sys/block/sdX/device/delete

Thanks, it worked perfectly. I saw it removed from the unassigned devices. I took it out and put the new drive it and after I refreshed the screen I saw the new drive listed. I had to press a button for the clear starts in order to access the preclear button. I guess the addon didn't notice it's a different drive.
