Action
Replace the failed hard disk drive (see "Removing a hot-swap hard disk drive" on
page 171 and "Replacing a hot-swap hard disk drive" on page 172).
1. Make sure that the installed hard disk drive or ServeRAID adapter is supported.
For a list of supported optional devices, see

2. Observe the associated yellow hard disk drive status LED. If the LED is lit, it
indicates a drive fault.
3. 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.
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
diagnostics program 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 5).
• 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 5. If the activity
of the LEDs changes, return to 2.
5. 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.
6. Reseat the backplane power cable and repeat steps 2 through 4.
7. Reseat the backplane signal cable and repeat steps 2 through 4.
8. Suspect the backplane signal cable or the backplane:
• If the server has hot-swap bays:
a. Replace the affected backplane signal cable.
b. Replace the affected backplane.
9. See "Problem determination tips" on page 110.
Make sure that the hard disk drive, SAS/SATA 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 110.
