Symptom Action
A replacement hard disk drive
does not rebuild. 1. Make sure that the hard disk drive is recognized by the adapter (the green hard
disk drive activity LED is flashing). If it is not recognized, see A newly installed
hard disk drive is not recognized1 on page 184.
2. Review the SAS/SATA RAID adapter documentation to determine the correct
configuration parameters and settings.
An yellow hard disk drive
status LED does not accurately
represent the actual state of
the associated 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.
b. Reseat the SAS/SATA adapter.
c. Reseat the backplane signal cable and backplane power cable.
d. Reseat the hard disk drive.
e. Turn on the server and observe the activity of the hard disk drive LEDs.
2. See “Problem determination tips” on page 198 for more information.

• Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
• See Chapter 5 “Parts listing, Lenovo System x3750 M4 Type 8753” on page 203 to determine which

Symptom Action
The server resets (restarts)
occasionally. 1. Check the IMM2 event log for messages associated with the restart event.
2. If the reset occurs during POST and the POST watchdog timer is enabled (click
System Settings --> Recovery --> System Recovery --> POST Watchdog
Timer
in the Setup utility (see “Starting the Setup utility” on page 135) to see
the POST watchdog setting), make sure that sufficient time is allowed in the
watchdog timeout value (
POST Watchdog Timer ). If the server continues to
reset during POST, see Appendix C “UEFI/POST error codes” on page 479 and
Appendix B “DSA diagnostic test results” on page 319.
3. If the reset occurs after the operating system starts, disable any automatic
server restart (ASR) utilities, such as the IBM Automatic Server Restart IPMI
Application for Windows, or any ASR devices that are be installed.
Note: ASR utilities operate as operating-system utilities and are related to the
IPMI device driver. If the reset continues to occur after the operating system
starts, the operating system might have a problem; see “Software problems”
on page 195.
