The correct answer is C. Reboot the server, start the RAID utility from the BIOS, and expand the RAID 6 with the two new. Expanding an existing hardware RAID 6 configuration requires using the RAID controller's utility during the server's boot process to recognize and integrate the new physical disks into the array.
Question
A technician ordered two additional hard drives to expand an existing RAID 6 configuration. The technician added the new disks and then rebooted. After rebooting, the technician did not see the additional space in the existing disk, and the OS detected two new disks that needed signatures. Which of the following should the technician complete next to expand the existing RAID configuration?
Options
- AModify the existing disk to a dynamic disk and add the two new raw disks to the existing array.
- BAllow the OS to write GPT signatures to the disks and add them as dynamic disks to the existing
- CReboot the server, start the RAID utility from the BIOS, and expand the RAID 6 with the two new
- DUse the software RAID in the OS to create a RAID 0 with the existing array and the two new

Why each option
Expanding an existing hardware RAID 6 configuration requires using the RAID controller's utility during the server's boot process to recognize and integrate the new physical disks into the array.
Modifying an existing disk to a dynamic disk and adding raw disks are software RAID or OS-level disk management actions, which are not used for expanding a hardware RAID array.
Allowing the OS to write GPT signatures and adding disks as dynamic disks relates to OS-level disk management, which is separate from expanding a hardware RAID array controlled by the RAID card.
For hardware RAID configurations like RAID 6, the expansion process is managed by the RAID controller's firmware. This utility is typically accessed via the BIOS or UEFI during server boot, allowing the technician to add the new physical disks to the existing array and expand its logical volume.
Using software RAID in the OS to create a RAID 0 with the existing array would destroy the current hardware RAID 6 configuration and create a new, less fault-tolerant array, which is incorrect for expanding an existing RAID 6.
