Hello ,

  DL380 has hot plug option. So you can replace disks with newer one when server is working. But i dont prefer this way to prevent any accident. I recommend you to shutdown  server  and replace all. But you mentioned one by one replacement. I think you want to transfer data to newer disks. If yes you can transfer c1rrent datas to external disk or network shared drive. Then replace disk and transfer data from usb or network.  If you want to replace one by one do not forget current raid settings will add 500 GB disk as 146 GB. So you remove all and plug newer ones. And also create a newer raid settings.

Thanks ndivani,
I know that I can move the data to external device and then replace the disks and move back the data.
But I need to transfer back and forth almost 600 giga and it will take me forever , that's way I am looking for a much faster solution.

last time i had 680 Gb data to be transferred with dl380. I upgraded like that :

- i plugged newer disks to another server for temporary.
- I transferred current data to newer disks
- Then replaced disks .
 This way is faster than first suggestion.If your servers have connection each others with backbones then speed will be better.
