A reconstruction occurs when you change the RAID level of an array or add a physical drive to an existing array. RAID level migration changes the array from one RAID level to another. Online capacity expansion is the addition of hard disk drives to increase storage capacity. You can perform a reconstruction while the system continues to run, without having to reboot. This avoids downtime and keeps data available to users.NOTE: After you start the reconstruct process, you must wait until it is complete. Do not reboot, cancel, or exit until the reconstruction is complete. NOTE: When performing a RAID level migration or an online capacity expansion, a fictional disk may appear in the Windows Disk Management, Dell OpenManage Array Manager, or Dell OpenManage Storage Services application, if the system is rebooted before the process is finished. This disk can be ignored and will disappear once the RAID level migration or online capacity expansion is complete.
Performing a RAID level migration on a clustered system will change the system to non-clustered mode, causing a cluster mismatch error if the system is rebooted.NOTE: An automatic drive rebuild will not start if you replace a drive during a RAID level migration or an online capacity expansion. The rebuild must be started manually after the expansion or migration procedure is complete.
Perform the following steps to reconstruct a drive:
A window entitled "Reconstructables" displays. This contains the logical drives that can be reconstructed. You can press <F2> to view logical drive information or <Enter> to select the reconstruct option.
The next reconstruction window displays. The options on this window are <spacebar> to select or deselect a drive, <Enter> to open the reconstruct menu, and <F3> to display logical drive information.
The menu items are RAID level, stripe size, and reconstruct.
You are prompted to start the reconstruction. A progress bar for the reconstruction displays.
