Hard-Drive Indicator Codes
Each hard-drive carrier has two indicators: a busy indicator and a status indicator (see
Figure 2
-6
). The indicators provide information on the status of the
respective hard drive.
Figure 2-6. Hard-Drive Indicators
Table 2
-5
lists the drive status indicator codes. 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 "preparing for removal" code appears. After the replacement drive is installed, the
"preparing for operation, drive online" code appears.
The drive-busy indicator signifies whether the hard drive is active on the SCSI bus. This indicator is controlled by the hard drive.
