Action
• 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.
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. Reseat the backplane configuration cable and repeat steps 1 through 3.
8. Suspect the backplane signal cable or the backplane:
• Replace the affected backplane signal cable.
• Replace the affected backplane.
9. Run the DSA tests for the SAS/SATA adapter and hard disk drives (see
"Dynamic System Analysis" 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.
10. See "Problem determination tips" on page 142.
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.
1. Review the storage subsystem logs for indications of problems within the
storage subsystem, such as backplane or cable problems.
2. See "Problem determination tips" on page 142.
1. Make sure that the hard disk drive is recognized by the adapter (the green hard
disk drive activity LED is flashing).
2. Review the SAS/SATA RAID adapter documentation to determine the correct
configuration parameters and settings.
1. 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" on page 124).
2. Use one of the following procedures:
• If the drive passes the test, replace the backplane.
• If the drive fails the test, replace the drive.
1. 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:
a. Turn off the server.
