Better to shut down the server and then insert the new drive. If the HDD you have, have two arms that are purple or port coloured then Yes you have hot pluggable HDD.

I want to make 100% sure that these drives are hot pluggable and that I can simply insert the extra disk whilst the server is still running. The server is a Proliant 2500.
