Verifying Hard Drive Operation

Each hard drive has an activity LED indicator on the front of the drive. See
NOTE: Only the Activity LED is used. The Status LED is not monitored by HP-UX.
Figure 82 LED Apertures on Hard Drive
Lightpipes on the disk drive transmit light to these apertures from LEDs on the inside
rear of the hot-swap mass storage cage. Verify that the LED shows the correct activity
indication for all disk drives that you installed:
1. Turn on power to the server and display monitor.
2. During the boot sequence, watch the Activity LED on each hard drive. The LED
quickly cycles from amber to green. The LED stays steady green until the drive
spins up.
3. If the activity LED is illuminated on any disk drive, the drive cage might not be
correctly installed. Check installation as follows:
