SCSI Hard-Drive Indicators
Each SCSI hard-drive carrier has two indicators: a busy indicator and a status indicator (see Figure 1-3 ). The indicators
provide information on the status of the respective hard drive. Table 1-5 lists the drive indicator codes.
Figure 1-3. SCSI Hard-Drive Indicators
Different codes display as drive events occur in the system. For example, in the event of a hard-drive failure, the "drive fail"
code appears. After the drive is selected for removal, the "prepared for removal" code appears. After the replacement drive is
installed, the "prepared for operation, drive online" code appears.
NOTE: The drive-busy indicator signifies whether the hard drive is active on the SCSI bus. This indicator is controlled
by the hard drive.
