How to properly rebuild virtual disks
All,
I have a Dell PowerEdge R630 with a Perc H730 controller running iDRAC 8 and have remote IPMI access. I need to replace all of the drives without downtime and I am struggling to find the correct documentation on how to rebuild these drives. Here's where I am currently at:
1) There are a total of 3 Virtual Disks, each in a RAID 1 (Mirror) configuration, as each as 2 physical drives, which is a total of 6 physical. I had 2 free spare slots. (the drives were 0:1:0, 0:1:1,0:1:2,0:1:3,0:1:4 and 0:1:5)
2) I added two new physical drives into the empty slots, they appeared as global hot spares.
3) I could not find a proper process on how to add a global hot spare into an existing virtual, so I finally just had remote hands pull physical disk 0:1:2 from the system. The hot spare rebuilt but left me showing 0:1:2 was missing from the system.
4) After the rebuilt was completed and logged in storage events, I had remote hands move the hotspare in 0:1:6 (which had the remote data rebuilt) into the slot of 0:1:2 hoping that it would see the data as consistent and return to a normal state. However, it detected it as 'Foreign' and tagged it as 0:2:
5) Knowing that was not what I wanted, I moved that hotspare from the physical slot 0:1:2 back to 0:1:6 and tried inserting a NEW drive in 0:1:2.
Now I have slot #6 has 0:6 with a state of Foreign. Slot #2 has a ready disk in 0:1:2, and Slot #7 is my OTHER hotspare as 0:1:7. My virtual disk 1 is showing as degraded, with 0:1:3 and 0:1:7
Through IPMI/iDRAC8 what is the proper way to move a global hotspare into being actually part of a virtual disk array?
Secondarily, how can I get my first global hotspare, which had rebuilt virtual disk 1, back to not being detected as foreign?

It looks like virtual disk 1 rebuilt itself. Now I show physical 0:1:2 as online, and my virtual disk 1 as online. It is now made up of 0:1:3 (original) and 0:1:7 which was my second hotspare.
The first hotspare, which got marked as foreign when I moved it, is still marked as foreign. And the clean drive I inserted into 0:1:2 is online but not a part of any virtual disk, but its also not marked as a hot spare. I really need to know the proper process for this.

Hello, thanks for choosing Dell and welcome to our community.
First and foremost, data backup of course
Then Without hotspare remove VD 0:1:0
New disk in
Rebuilding
remove0:1:1
new disk in
rebuild again
Then Online Capacity Expansion (OCE)

First and foremost you should never move a disk with data on it to a different slot in a system as it runs a high risk of corrupting your RAID / Data .
As for fixing your 'Foreign drive' issue, that is easy enough.
Reboot System -> Cntrl+R to enter PERC BIOS, select the controller and press F2 > Foreign Config > Import
CTRL+N to enter Physical Disk Management screen to verify status is good.
I laterif you come across a disk being 'Ready' but not rebuilding Select Disk -> press F2 -> Rebuild to start the process.
