I'm having a lot of trouble figuring this out, so hopefully someone here can help. I recently tried to add some storage to my file server (RAID 5) array. I used the HP ACU to extend the array and now it shows two logical drives. One drive has all the data and the other is empty storage. When I look in the Disk Management MMC it shows this second logical drive as an entirely different disk from my file server, and Diskpart doesn't even see it.
In the ACU software, it gives me the option to delete the logical drive. If I delete the one with nothing on it, will the empty space be absorbed by the other? If not, what is the best way to merge these disks?
My goal is to utilize all the storage I added as one logical drive.
