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 4, “Parts listing, System x3690 X5 Types 7147, 7148, 7149, and 7192,” on page 249 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.
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:
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 81).
v
If the adapter 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 adapter fails the test, disconnect the backplane signal cable from the
adapter and run the tests again.
v
If the adapter fails the test, replace the adapter.
9.
See “Problem determination tips” on page 246.
Multiple hard disk drives fail.
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.
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.
