v Follow the suggested actions in the order in which they are listed in the Action column until the problem is

solved.

v See Chapter 7, “Parts listing, RS210 Types 6531, 6532, 6533, and 6534,” on page 177 to determine which

components are customer replaceable units (CRU) and which components are field replaceable units (FRU).

v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a

Trained service technician.

v Go to the Lenovo support Web site at http://www.lenovo.com/support to check for technical information, hints,

tips, and new device drivers or to submit a request for information.

Symptom Action

A newly installed hard disk

drive is not recognized.

1. Observe the associated amber hard disk 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 hard disk drive

backplane.

3. Observe the associated green hard disk drive activity LED and the amber

status LED:

v 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

hard disk drive test to determine whether the drive is detected.

v 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.

v If neither LED is lit or flashing, check the hard disk drive backplane (go to

step 4).

v 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 4. 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.

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:

v Replace the affected backplane signal cable.

v Replace the affected backplane.

8. Run the diagnostic tests for the SAS/SATA controller and hard disk drives (see

“Diagnostic tools” on page 19).

v If the controller passes the test but the drives are not recognized, replace the

backplane signal cable and run the tests again.

v Replace the backplane.

v If the controller fails the test, disconnect the backplane signal cable from the

controller and run the tests again.

v If the controller fails the test, replace the controller.

9. See “Problem determination tips” on page 104..

Multiple hard disk drives fail. Make sure that the hard disk drive, SAS/SATA RAID controller, and server device

drivers and firmware are at the latest level.

Important: 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.

1. Review the storage subsystem logs for indications of problems within the

storage subsystem, such as backplane or cable problems.

2. See “Problem determination tips” on page 104.
