RAID firmware fails one of the mirrored disks it automatically replaces the failed disk with a hot spare disk and then resynchronizes the mirrored data The firmware automatically receives a notification when a hot spare replaces the failed disk and it then designates that disk as the new hot spare The OCE feature enables you to expand the capacity of an existing two disk Integrated Mirroring RAID 1 volume by replacing the original disk drives with higher capacity drives that have the same protocol SAS or SATA NOTE The new drives must have at least 50 GB more capacity than the original drives of the volume After you replace the disk drives and run the OCE command you must use a commercial tool specific to the operating system to move or increase the size of the partition on the volume The Integrated RAID firmware supports a background media verification feature that runs at regular intervals when the mirrored volume is in the Optimal state If the verification command fails for any reason the firmware reads the other disk s data for this segment and writes it to the failing disk in an attempt to refresh the data The firmware periodically writes the current media verification logical block address to nonvolatile memory so that the media verification can continue from where it stopped prior to a power cycle Page 11 Chapter 2 Overview of Integrated RAID Mirrored Volumes Mirrored Volume Features SAS2 Integrated RAID Solution U
