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.
• From the System Manager, select the System Summary tab to check the enclosure health status
or select the Hardware Status tab to identify a failed component. See “Using the System
Manager” (page 30) for more information.
• 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 26) for more
information.
• Look for a blinking amber LED on the component. See “Component LEDs” (page 34) for LED
information.
Verifying proper operation
After replacing a system component, check the following to verify that the component is operating
properly:
• If applicable, verify that the green LED is lit continuously or blinking. If not, try reseating the
component.
• From the System Manager, navigate to the Hardware Status and System Summary tabs to
confirm the component failure alert no longer appears. The status should be (Good).
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
