Adding a failed drive to DS6100

Good Morning,
Again,
issues trying to add the new drive to the existing (?? Pool, or raid). Disk Manager shows it there and initialized. I took a screen shot but don’t know how to add it.

your first step is to determine of you are using windows storage spaces or WD Raid. Go to windows server manager and find storage spaces and see if it is configured. if not you need to figure out how to launch the wd raid utility

Thanks,
I got it figured out after reading many articles on the internet. It is raid 5, but you have to format the drive first, then go to virtual disk 1 (WD) choose it, then tell it to rebuild (using the WD Tray software.)
A lot different then server 2008 r2. Thanks for all the input.
