Lenovo x3530 M4 Installation And Service Manual page 143

• Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
• See Chapter 5 "Parts listing, IBM System x3530 M4 Type 7160" on page 147 to check if a component is a
consumable, structural, or FRU part.
• If an action step is preceded by "(Trained technician only)," that step must be performed only by a trained
technician.
Symptom
A hard disk drive has failed,
and the associated yellow hard
disk drive status LED is lit.
A newly installed hard disk
drive is not recognized.
Multiple hard disk drives fail.
Action
Replace the failed hard disk drive.
1. Observe the associated yellow 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 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 DSA
hard disk drive test to determine whether the drive is detected.
• 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 hard disk drive backplane (go to
step "Hard disk drive problems" on page 128).
• 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 "Hard disk drive
problems" on page 128. 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:
a. Replace the affected backplane signal cable.
b. Replace the affected backplane.
8. Run the DSA tests for the SAS/SATA adapter and hard disk drives (see "Running
the DSA Preboot diagnostic programs" on page 124).
• 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.
9. See "Problem determination tips" on page 143.
Make sure that the hard disk drive, SAS/SATA RAID adapter, 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.
