I am working with a Dell poweredge T610, I had the main OS HDD crashed. I put a new HDD and put the OS disk in, problem is when I go through the prompts and get to the part where I have to choose the HDD to install the OS it shows no HDD available.
Note: I am not familiar with Dell servers.
This is not specific to Dell servers - or servers in general - it is an issue you can easily see on desktops and laptops as well. You need drivers for the storage controller.
Which controller are you using?
