This section displays RAID array information. Five banners appear in this section.
RAID array status
• Status—Displays the status of the RAID array. The following conditions are valid:
• Good—The RAID array is fully operational.
• Reduced—The RAID array is operating in a degraded or reduced state. One or more of the physical drives
that make up the RAID array are either missing or failed. However, the RAID array can continue to operate
without data loss.
• Failed—The RAID array is not operational.
• Reconstructing—The RAID array is regenerating the data from a failed physical drive onto a replacement
drive that is part of the RAID array. All user data remains available during the reconstruction process, but
some performance reduction might occur when a request requires access to the device being reconstructed.
• Initialization—The controller is writing its file structure onto the member devices of a RAID array.
• RAID Level—Displays the RAID level and a brief description of the selected RAID array.
