Not all drives are recognized by the DSA hard disk
drive diagnostic test. |
Remove the drive that is indicated by DSA (see Removing hot-swap drives or Removing a simple-swap SATA drive); then, run the hard disk drive
diagnostic test again (see DSA diagnostic test results). 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. |
Remove the drive that is indicated by DSA (see Removing hot-swap drives or Removing a simple-swap SATA drive); then, run the hard disk drive diagnostic test again (see DSA diagnostic test results). If the remaining drives
are recognized, replace the drive that you removed with a new one. |
A hard disk drive has failed, and the associated yellow
hard disk drive status LED is lit. |
Replace the failed hard disk drive. |
A newly installed hard disk drive is not recognized. |
- Observe the associated yellow 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 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).
- 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. If the activity of the LEDs changes, return to step 1.
- 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 1 through 3.
- Reseat the backplane signal cable and repeat steps 1 through 3.
- Suspect the backplane signal cable or the backplane:
- Replace the affected backplane signal cable.
- Replace the affected backplane.
- Run the DSA tests for the SAS/SATA adapter and hard disk drives
(see Running the DSA Preboot diagnostic programs).
- 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.
- See Problem determination tips.

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. |
- Review the storage subsystem logs for indications of problems
within the storage subsystem, such as backplane or cable problems.
- See Problem determination tips.
|
A replacement hard disk drive does not rebuild. |
- Make sure that the hard disk drive is recognized by the adapter
(the green hard disk drive activity LED is flashing).
- Review the SAS/SATA RAID adapter documentation to determine the
correct configuration parameters and settings.
|
A green hard disk drive activity LED does not accurately
represent the actual state of the associated drive. |
- If the green hard disk drive activity LED does not flash when
the drive is in use, run the DSA disk drive test (see Running the DSA Preboot diagnostic programs.
- Use one of the following procedures:
- If the drive passes the test, replace the backplane.
- If the drive fails the test, replace the drive.
|
A yellow hard disk drive status LED does not accurately
represent the actual state of the associated drive. |
- If the yellow hard disk drive LED and the RAID adapter software
do not indicate the same status for the drive, complete the following
steps:
- Turn off the server.
- Reseat the SAS/SATA adapter.
- Reseat the backplane signal cable and backplane power cable.
- Reseat the hard disk drive.
- Turn on the server and observe the activity of the hard disk drive
LEDs.
- See Problem determination tips.
