How To Increase the Size of an Active Intel® Virtual RAID on CPU (Intel® VROC) RAID Volume on Intel® Server Boards

• Unable to increase the size of the RAID volume.
• Unable to determine if the Intel® VROC option called Increase Size would work.

If the goal is to replace all drives with others of higher capacity, proceed with the below two options.

Option #1 (Starting from scratch)

1. Replace the drives.
2. Re-create the array.
3. Restore the data.

Option #2 (System is in production)

1. Replace one drive with another of higher capacity and wait for the rebuild to finish.
2. Repeat the process for each of the other drives. One at the time.
3. Use the Increase Size button next to the volume name from within the Intel® VROC Graphical User Interface (GUI) for Windows* to increase the RAID volume to fully utilize the new disk spaces. The Increase Size button is solely if there is additional free space in the existing array. For example, you have a 500 GB RAID 10 volume on 4x 1TB drives; you can then increase the volume using this option to fully utilize the remaining 500 GB free space.
   • You might need to also use Windows* Disk Management to increase the partition size to fully utilize the expanded RAID volume.
