5.2.10 Verifying the memory mode
If a memory module fails, the server will reboot and the defective module will be
disabled. As a result, the current operation mode (e.g. Mirrored Channel mode)
may no longer be available due to a lack of identical memory module pairs. In
this case, the operation mode will automatically revert to Independent Channel
Mode.
I For detailed information on memory operation modes available for your
server, refer to section "Modes of operation" on page 227.
After replacing the defective module(s) the memory operation mode is
automatically reset to its original state. It is recommended to verify that the
operation mode has been correctly.
Ê Enter the BIOS.
Ê Select the Advanced menu.
Ê Under Memory Status verify that none of the memory modules are marked as
Failed.
Ê Save your changes (if applicable) and exit the BIOS.
I For detailed information on how to access the BIOS and modify settings,
refer to the corresponding BIOS Setup Utility reference manual.
5.2.11 Verifying the system time settings
I This task only applies to Linux environments.
After the system board has been replaced, the system time is set automatically.
By default, the RTC (Real Time Clock) time standard is set as the local time.
If a Linux OS is used and the hardware clock has been configured as UTC
(Universal Time, Coordinated) in the operating system, the BMC local time may
not be mapped correctly.
Ê After replacing the system board, ask the system administrator whether the
RTC or UTC time standard is to be used as system time.
I If the system time (RTC) is set to UTC, the SEL (System Event Log)
time stamps may differ from the local time.
Ê Enter the BIOS.
