About Your System
Table 1-5 lists the drive indicator patterns. 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:
If a RAID controller is not installed, only the "drive online" indicator pattern appears. The drive-activity
indicator also blinks when the drive is being accessed.

the system messages that can occur and the probable cause and corrective action for each message.
NOTE:
If you receive a system message that is not listed in Table 1-6, check the documentation for the application
