LSI Firmware, Service Processor, and BIOS Issues 25
Workaround
Load the optimal defaults as described in “Upgrading BIOS Without Changing and
Saving Optimal Defaults Might Result in Increased Memory Latency (6306622,
6299794)” on page 24
.
BIOS Boot Order Lost After Reset Testing
(6302703)
If you reset the system and interrupt BIOS power-on self-test (POST) early in the
boot process, the system might lose the virtual USB devices from the boot order and
stop booting from the drive. The BIOS rewrites some CMOS registers during POST
and does not immediately update the CMOS checksum.
Workaround
Unplug and then replug the system to cause a full hardware reset. All USB devices
should reappear.
DIMM Fault LEDs Are Not Implemented At This
Time (6324863)
The troubleshooting and maintenance documentation for the product describes the
future functionality of the DIMM fault LEDs. When there is an noncorrectable error,
it is expected that the DIMM fault LEDs will light the DIMM-slot ejector levers to
indicate the faulty DIMM pair. This fix is planned for a future release.
Workaround
None.
System Does Not Detect Supported HBA Card
During Bootup Process (6272514)
If a supported host bus adapter (HBA) card is plugged in to Slot 1 on a Sun Fire
X4100 server, or Slots 1-4, on a Sun Fire X4200 server, the card is not detected by the
BIOS during the bootup process.
