| Resetting ILOM may cause the host to hang. Possibly CPU faults may also occur at the same time during the boot after force resetting the host. |
Host hung after ipmiflash completing reflashing ILOM, and ILOM shows following message repeatedly:
BTKCS Driver BT: "pod" Host timed out trying to write, ifc->host_busy @ 0x08
Host hang with blinking cursor on VGA output waiting for system to reboot
FMA may report: An internal fault on a processor has occurred |
Workaround: Avoid unnecessary reboots of the ILOM SP.
Resolution: Update system to the latest ILOM firmware (SW 1.2.1 or later) |
| If Power Management for the the system is disabled the server will experience a performance loss. |
If the customer disables the "Power Technology" option in the BIOS it will cause the system to run the processors at their minimum clock frequency causing system performance loss. |
Workaround: The Intel Power Technology option in the BIOS should be left enabled and all of the sub options should be left at their default settings.
Resolution: Update system to the latest ILOM firmware (SW 1.2.0 or later)

| "Highly Configured" X3-2L servers with several PCIe cards installed may observe long boot/reboot times during the BIOS initialization. |
This issue has specifically been observed on systems with 5 Emulex HBAs installed where boot time for the BIOS initialization could be seen as long as 24 minutes.
This behavior is completely normal and is due to the time it takes for the system to load each card's Option ROM. The BIOS setting's default is for all cards to have their Option ROMs enabled so that they get loaded at boot time. This allows for access to the PCIe card's BIOS level utilities and the ability to "see" the devices at the hardware level where the customer may want to be able to configure the system to boot from the PCIe card.
|
Workaround: To avoid the possible "long" boot times that may be observed due to the time it takes to load the Option ROMs from all of the installed cards the customer may choose to disable the Option ROM from the BIOS setup so that it is not loaded at boot time. Whether or not to enable the Option ROMs for the installed cards will depend upon the systems configuration (but after the initial system configuration many times if the system is not using the device as a boot device it may be disabled) and is something the customer will need to decide for their particular usage.
To disable the Option ROMs for specific PCIe cards go into the BIOS setup screens and navigate to the "IO" tab, then the "Add-in Cards" section. Each slot location may be selected to disable/enable the Option ROM. See the BIOS IO Menu Selections of the service manual for details on editing these values.
