18 About Your System
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.
