Server cannot recognize a hard drive
Complete the following steps until the problem is solved.
1. Observe the associated yellow hard disk drive status LED. If the LED is lit, it indicates a drive fault.
2. If the status LED is lit, remove the drive from the bay, wait 45 seconds, and reinsert the drive, making
sure that the drive assembly connects to the hard disk drive backplane.
3. Observe the associated green hard disk drive activity LED and the yellow status LED and perform
corresponding operations in different situations:
• If the green activity LED is flashing and the yellow status LED is not lit, the drive is recognized by the
controller and is working correctly. Run the diagnostics tests for the hard disk drives. When you start
a server and press the key according to the on-screen instructions, the LXPM interface is displayed
by default. (For more information, see the "Startup" section in the LXPM documentation compatible
with your server at
You can perform hard drive diagnostics from this interface. From the Diagnostic page, click Run
Diagnostic ➙ Disk Drive Test.
• If the green activity LED is flashing and the yellow status LED is flashing slowly, the drive is
recognized by the controller and is rebuilding.
• If neither LED is lit or flashing, check whether the hard disk drive backplane is correctly seated. For
details, go to step 4.
• If the green activity LED is flashing and the yellow status LED is lit, replace the drive. If the activity of
the LEDs remains the same, go to step Hard disk drive problems. If the activity of the LEDs changes,
return to step 1.
4. Make sure that the hard disk drive backplane is correctly seated. When it is correctly seated, the drive
assemblies correctly connect to the backplane without bowing or causing movement of the backplane.
