Question
A technician is configuring a new server. After using the RAID setup program to create a new RAID array, the OS installer is not able to find storage on which to write. Which of the following is the MOST likely reason this may happen?
Options
- AThe technician did not provide drivers to support the controller.
- BThe technician did not enable UEFI in the server BIOS.
- CThe technician did not allow time for the new array to initialize.
- DThe OS is not supported on the server hardware.

Why each option
After creating a RAID array, the OS installer may not detect storage because the array requires an initialization period before it becomes fully accessible.
The RAID setup program runs from controller firmware and does not require OS-level drivers, so if the array was successfully created, the controller is functional enough to present the volume once initialized.
UEFI vs. Legacy BIOS mode affects how the system boots and handles partition tables, but does not prevent a RAID array from being presented to an OS installer after it is created.
Hardware RAID arrays, particularly parity-based arrays like RAID 5 or RAID 6, must complete an initialization process after creation during which the controller writes parity data across all member drives. Until this initialization completes, the logical volume may not be fully presented to the system, causing the OS installer to report no available storage. Waiting for initialization to finish before launching the OS installer resolves the issue.
OS compatibility issues would manifest as installation errors or unsupported hardware warnings, not as a complete failure to detect any storage device.
