Verifying component failure

Use the following methods to verify component failure:

• Analyze any failure messages received. Fault monitoring software from HP provides a

recommended action.

• You can also use the System Management Homepage to identify hardware problems. For

example, to identify the affected enclosure, select Unit Identification Device in the Enclosure

pane and then on the Unit Identification Device window, click On. The blue UID indicator on

the controller enclosure blinks. See “HP System Management Homepage” (page 33) for more

information.

• Look for a blinking amber LED on the component. See “Component LEDs” (page 37) for LED

information.

Verifying proper operation

After replacing a system component, verify that the green LED is lit continuously or blinking (if

applicable). If not, try reseating the component.

Wait times for hard disks

If the hard drive is part of a volume, the following wait times apply:

Removal: Less than three seconds for the LED to turn off

Insert:

• Less than one second for first disk activity

• Less than 15 seconds for the disk to be ready for REBUILD. The LED blinks at 1 Hz.

NOTE: The transition to solid green depends on how long the REBUILD takes (the LEDs

indicate REBUILD).

If the hard drive is not part of a volume, the following wait times apply:

Removal: No indication appears because the LED is already off

Insert:

• Less than one second for the first disk activity to appear

• Less than 15 seconds for the disk to be ready to use
