Table 1-3 lists the drive indicator patterns for RAID hard drives. Different patterns are displayed as drive
events occur in the system. For example, if a hard drive fails, the "drive failed" pattern appears. After the
drive is selected for removal, the "drive being prepared for removal" pattern appears, followed by the "drive
ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for
operation" pattern appears, followed by the "drive online" pattern.
NOTE:
For non-RAID configurations, only the drive-activity indicator is active. The drive-status indicator is off.
