HP Storage P2000 G3 MSA – Delete a vdisk and create a new vdisk

One of the vdisk on the HP Storage P2000 G3 MSA was showing fault.
I got an error message saying that “The virtual disk is offline. Disks may be down or missing. Data may be lost”.

We had 2 hdd failed in the vdiks, we had this failed hdd’s replaced.
The 2 hdd failure has caused the raid 5  vdisk to fail.

Now I couldn’t re-add the new disk because of the raid failure.

So I had to delete the vdisk and create a new vdisk and volumes under the vdisk.
