3.6 System Monitoring
Apart from the power button LED and the hard drive activity LED, there are no other system monitoring LEDs
on the controller.
3.6.1 Monitoring Hard Disk Drives
Hard drive read/write activity is indicated by the front panel LED (arrow in Figure 3-9).
3.6.2 Recognizing Hard Drive Failures
NOTICE: Occasionally, a drive that has previously failed may seem to be operational after the system
is power-cycled or after the drive has been removed and reinserted. However, continued use of such
marginal drives could eventually result in data loss. Replace the marginal drive as soon as possible.
There is only one way in which a hard drive reveals signs of failure:
A POST message lists failed drives whenever the system is restarted, as long as the controller detects at least
one functional drive.
