Server cannot recognize a drive
Complete the following steps until the problem is solved.
1. Observe the associated yellow 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 drive backplane.
3. Observe the associated green 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 drives. When you start a server
and press the key according to the on-screen instructions, the LXPM is displayed by default. (For
more information, see the "Startup" section in the LXPM documentation compatible with your server
at

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 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.
4. Make sure that the 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.
5. Reseat the backplane power cable and repeat steps 1 through 3.
6. Reseat the backplane signal cable and repeat steps 1 through 3.
7. Suspect the backplane signal cable or the backplane:
• Replace the affected backplane signal cable.
• Replace the affected backplane.
8. Run the diagnostics tests for the drives. When you start a server and press the key according to the on-
screen instructions, the LXPM is displayed by default. (For more information, see the "Startup" section in
the LXPM documentation compatible with your server at
