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 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 interface is displayed by default.
You can perform hard drive diagnostics from this interface. From the Diagnostic page, click Run
