| Not all drives are recognized by the hard disk
drive diagnostic test. |
Remove the drive that is indicated by the diagnostic
tests; then, run the hard disk drive diagnostic test again. 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 hard disk drive that was being tested
when the server stopped responding, and run the diagnostic test again.
If the hard disk drive diagnostic test runs successfully, replace
the drive that you removed with a new one. |
| A hard disk drive was not detected while the operating
system was being started. |
Reseat all hard disk drives and cables; then, run
the hard disk drive diagnostic test. |
| A hard disk drive passes the diagnostic Fixed Disk
Test, but the problem remains. |
Run the diagnostic SCSI Fixed Disk Test. See Running DSA Preboot diagnostic program. Note: This
test is not available on servers that have RAID arrays or servers
that have SATA hard disk drives.
|
| A hard disk drive has failed, and the associated
yellow hard disk drive status LED is lit. (hot-swap hard disk drives) |
- Reconfigure the integrated SAS/SATA controller with RAID capabilities
and the devices that are attached to it.
- Run the DSA disk drive test. See Dynamic System Analysis.
- If the drive fails the test, replace the 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 4).
- 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 4. 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.
SeeDynamic System Analysis.
- 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, RAID card,
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. (hot-swap hard
disk drives) |
- If the green hard disk drive activity LED does not flash when
the drive is in use, run the DSA disk drive test. See Dynamic System Analysis.
- 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. (hot-swap hard
disk drives) |
- If the yellow hard disk drive LED and the RAID card software do
not indicate the same status for the drive, do the following:
- Turn off the server.
- Reseat the SAS/SATA adapter.
- Reseat the backplane signal cable and 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.
