Can I mount a Virtual Drive (created by Hardware Raid Controller) when using separate SSD to boot?

Hello all!

I am currently struggling with mounting a virtual drive. I am not the most experienced Linux user, but I am learning.

I am running Ubuntu 16.04 if that is helpful. Earlier I only had one SSD which was my boot drive. I now want to add a RAID 5 configuration to store data. It uses a hardware raid card, and in the WebBIOS for the card, I created a virtual drive in raid 5. running "sudo gparted" returns

"/dev/sda: unrecognized disk label", but it shows the correct size, so it is definitely seeing this virtual drive, however it is unallocated so I can not use it or mount it.

Does anyone have any suggestions?

The message means that /dev/sda is not partitioned, which you should expect right after creating the drive.

Before mounting the drive, you need to create a filesystem on it. If you use gparted (which I have never used), you probably need to:
  1. create a partition table (
  2. create a partition (
  3. create a filesystem (
  4. mount the filesystem (
There is no technical need for steps 1 and 2, but gparted might insist on them. Creating at least one partition is good practice, too, since it indicates the purpose of this drive to you or other people.

Strictly speaking you should be able to use the entire drive unpartitioned (I would personally), but that will lead to all sorts of confusion trying to use almost any document you find on the 'net.
I haven't looked at those links, but they should do the job, else simple enough to fix from the command line should you need to.
