Create new array with unassigned drive in Smart Array P410i

[stevenbork]

Hey guys

Background:
============================

- I have no experiencie managing RAID devices, so appreciate your patience with me.
- I don't have any way to reach the server locally or using KVM, only have remote SSH access.
- Server hardware: ProLiant DL380 G7 server, with Smart Array P410i running CentOS 7.x 64 bits.

Problem description:
============================

The owner of the server installed a 600GB SAS drive into the server, but I can't detect it with fdisk command. It seems normal, after I find out this server is using a RAID controller.
So, I guess the only way to use the drive will be to setup a RAID 0 for it, right? As I need to expand the available space asap.

Information about current disks and RAID setup:

I guess the drive he installed is the "unassigned" one, right? (physicaldrive 2I:1:6 (port 2I:box 1:bay 6, SAS, 600 GB, OK))

If so, can anyone tell me how to build a new array with RAID 0 for this 600GB unassigned device? (if this is the best solution, of course) As I don't want to touch the other arrays I see are already set up.

Appreciate your help.

Thanks!
