Let me provide some assistance on this one. I have just put a system together so I can share the possible screens you are going to get.
- First go to the Logical Tab and right click the Drive Group for your RAID 5
- Then, you need to choose the RAID level (in your case we are going to maintain the same RAID level 5).
- Select the drive you are going to add to the Disk Group.
- Review the summary of the changes and click Finish to start the process.
- Under the Dashboard you can check the progress of the operation.
PS: Make sure you extend your partition once the operation is completed. Feel free to contact our Intel Customer Support team for proper follow up of this process.
