If an action step is preceded by (Trained service technician only), that step must be performed only by a Trained service technician.
Go to the IBM support website at Lenovo Data Center Support to check for technical information, hints, tips, and new device drivers or to submit a request for information.
A hard disk drive has failed, and the associated amber hard disk drive status LED is lit.
Replace the failed hard disk drive.
A newly installed hard disk drive is not recognized.
Make sure that the installed hard disk drive or RAID adapter is supported. For a list of supported optional devices, see Lenovo ServerProven website.
Observe the associated amber hard disk drive status LED. If the LED is lit, it indicates a drive fault.
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 hard disk drive backplane.
Observe the associated green hard disk drive activity LED and the amber status LED:
If the green activity LED is flashing and the amber status LED is not lit, the drive is recognized by the controller and is working correctly. Run the DSA diagnostics program to determine whether the drive is detected.
If the green activity LED is flashing and the amber status LED is flashing slowly, the drive is recognized by the controller and is rebuilding.
If neither LED is lit or flashing, check the hard disk drive backplane (go to step Step 5).
If the green activity LED is flashing and the amber status LED is lit, replace the drive. If the activity of the LEDs remains the same, go to step Step 5. If the activity of the LEDs changes, return to step Step 2.
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.
Reseat the backplane power cable and repeat steps Step 2 through Step 4.
Reseat the backplane signal cable and repeat steps Step 2 through Step 4.
Suspect the backplane signal cable or the backplane:
Make sure that the hard disk drive, SAS/SATA adapter, and server device drivers and firmware are at the latest level.
Some cluster solutions require specific code levels or coordinated code updates. If the device is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you update the code.
Multiple hard disk drives are offline.
Review the storage subsystem logs for indications of problems within the storage subsystem, such as backplane or cable problems.
