Use this information to solve hard disk drive problems.
Table 29. Hard disk drive problems
• 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, Lenovo System x3750 M4 Type 8753” on page 203 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units (FRU).
• If an action step is preceded by (Trained service technician only), that step must be performed only by
a Trained service technician.
Symptom Action
Not all drives are recognized
by the DSA hard disk drive
diagnostic test. 1. Set up the RAID configuration before you run the DSA diagnostic tests.
2. Remove the drive that is indicated by DSA (see “Removing 2.5-inch and
1.8-inch hot-swap drives” on page 225); then, run the hard disk drive diagnostic
test again (see “Running the DSA Preboot diagnostic programs” on page 177).
3. If the remaining drives are recognized, replace the drive that you removed
with a new one.
The server stops responding
during the hard disk drive
diagnostic test.
1. Set up the RAID configuration before you run the DSA diagnostic tests.
2. Remove the hard disk drive that was being tested when the server stopped
responding (see “Removing 2.5-inch and 1.8-inch hot-swap drives” on page
225), and run the diagnostic test again (see “Running the DSA Preboot
diagnostic programs” on page 177).
3. If the hard disk drive diagnostic test runs successfully, replace the drive that
you removed with a new one (see “Replacing 2.5-inch and 1.8-inch hot-swap
drives” on page 226).
A hard disk drive has failed,
and the associated yellow hard
disk drive status LED is lit. Check the IMM2 event log for hard disk drive events and resolve the problem.
A newly installed hard disk
drive is not recognized. 1. Set up the RAID configuration.
2. Check the IMM event log for hard disk drive events and resolve the problem.
3. If the LED is lit, remove the drive from the drive bay, wait 45 seconds, and
reinsert the drive, making sure that the drive assembly connects to the hard
disk drive backplane.
4. 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 (see “Running
the DSA Preboot diagnostic programs” on page 177).
• 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 55 on page 184).
• If the green activity LED is flashing and the yellow status LED is lit, replace
the drive. If the activity of the LEDs remain the same, go to step 55 on page
184. If the activity of the LEDs changes, return to step 11 on page 184.
5. Make sure that a hard disk drive backplane is present to install the drive into.
6. 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.
