241 • Click Reconfigure Disks to reconfigure the storage system using the available disks. Caution: Reconfiguring the disks deletes all user information and all data on all the disks. 2 Follow step 2 of the previous section. Swapping hard disk drives If you are using RAID 5 + spare or RAID 10, you can move the HDDs from one slot to another whether or not the storage system is running. However, if you do this when the storage system is running, you can swap only two HDDs, and you must restart the system after you swap the HDDs. If you swap the HDDs when the storage system is not running, you can swap all four HDDs, and the system will function as it previously did when you restart it. Notes: • For RAID 5 + spare, if you swap the HDDs when the storage system is running, one of the swapped HDDs must be the spare. • For RAID 10, the swapped HDDs must be in different pairs. For example, you can swap HDD 1 and 3 or HDD 2 and 4, but not HDD 1 and 2, as those are members of the same pair. If the storage system is running when you swap the HDDs, the Disk Change Notification page displays. Click Shut Down and then restart the system. For all other disk configurations (linear, RAID 0, RAID 1, and RAID 5), you can swap the HDDs only when the storage system is powered off, and you can swap all four HDDs.
