Server cannot recognize a drive
Complete the following procedure to solve the problem.
1. Observe the associated yellow drive status LED. If the LED is lit, it indicates a drive fault.
2. If the 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:
• 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 F1, the Lenovo XClarity Provisioning Manager V3 interface is displayed by default.
You can perform hard drive diagnostics from this interface. From the Diagnostic page, click

.
• 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 the drive backplane.
• 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 drive problems. If the activity of the LEDs changes, return to
step 1.
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 SATA/SAS adapter and drives. When you start a server and press F1,
the Lenovo XClarity Provisioning Manager V3 interface is displayed by default. You can perform drive
diagnostics from this interface. From the Diagnostic page, click

.
Based on those tests:
• If the adapter passes the test but the drives are not recognized, replace the backplane signal cable
and run the tests again.
• Replace the backplane.
• If the adapter fails the test, disconnect the backplane signal cable from the adapter and run the tests
again.
• If the adapter fails the test, replace the adapter.
Multiple drives fail
