System x3850 X6 and x3950 X6 Installation and Service Guide
Action
1. Set up the RAID configuration before running the DSA diagnostics.
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
238), and run the diagnostic test again (see "Running the DSA Preboot
diagnostic programs" on page 166).
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 240).
1. Set up the RAID configuration (see "Configuring RAID arrays" on page 140).
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 amber status
LED:
• If the green activity LED is flashing and the amber 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 166).
• If the green activity LED is flashing and the amber 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 174).
• If the green activity LED is flashing and the amber status LED is lit, replace
the drive. If the activity of the LEDs remain the same, go to step 55 on page
174. If the activity of the LEDs changes, return to step 11 on page 174.
5. Make sure that there is 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.
7. Reseat the backplane power cable and repeat steps 11 on page 174 through 33
on page 174.
8. Reseat the backplane signal cable and repeat steps 11 on page 174 through 33
on page 174.
9. The backplane signal cable or the backplane is the potential problem:
a. Replace the affected backplane signal cable.
b. Replace the affected backplane.
10. Run the DSA tests for the SAS/SATA adapter and hard disk drives (see
"Running the DSA Preboot diagnostic programs" on page 166).
