Attempt to change to another DCPMM mode fails
After the DCPMM mode is changed and the system is successfully restarted, if the DCPMM mode stays the
same instead of being changed, check the DRAM DIMMs and DCPMM capacity to see if it meets the
requirement of the new mode (see “DC Persistent Memory Module (DCPMM) setup” on page 178).
Extra namespace appears in an interleaved region
If there are two created namespaces in one interleaved region, VMware ESXi ignores the created
namespaces and creates an extra new namespace during system booting. Delete the created namespaces
in either the Setup Utility or the operating system before the first booting with ESXi.
Hard disk drive problems
Use this information to resolve issues related to the hard disk drives.
• “Server cannot recognize a hard drive” on page 255
• “Multiple hard drives fail” on page 256
• “Multiple hard drives are offline” on page 256
• “A replacement hard disk drive does not rebuild” on page 256

Server cannot recognize a hard drive
Complete the following steps until the problem is solved.
1. Observe the associated yellow hard disk drive status LED. If the LED is lit, it indicates a drive fault.
2. 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.
3. 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 diagnostics tests for the hard disk drives. When you start
a server and press F1, the Lenovo XClarity Provisioning Manager Lite interface is displayed by
default. You can perform hard drive diagnostics from this interface. From the Diagnostic page, click

HDD test
.
• 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.
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. Suspect the backplane signal cable or the backplane:
• Replace the affected backplane signal cable.
• Replace the affected backplane.
