Important Information
1. After installing this firmware and rebooting, a consistency check will automatically begin on RAID 5 and 50 virtual disks with 5 or more physical disks to ensure parity information is correct.
2. The consistency check cannot be terminated and will resume at its last point following a reboot.
3. This consistency check will appear as a Background Initialization but will only perform a consistency check with no data being modified.
4. The consistency check runs in the background, allowing the virtual disks to remain accessible during the check.
5. While this background check is designed to minimize performance impact, some degradation in performance may occur until the check is complete, especially under heavy I/O.
