1 Onboard CTRL <C> RAID 0, 1 creation appears to be slow and appears
to limit the number of RAID configurations.
Description Initializing a RAID 1(mirror) using the BIOS (CTRL-C) utility will take
approximately 1 hour per 5GB of drive space. There is also a limitation of
one logical drive per controller.
Implication For optimal performance the mirror must finish initialization before rebooting the
system or attempting to install the operating system on the mirror (though this is
not required). Typically, 1 hour for each 5Gigabytes of hard drive capacity is
required to complete initializing the mirror when using the onboard CTRL <C>
application.
RAID 1 mirror, 12-14
complete. Adding a 3rd drive configured as a "hot spare" will increase the time
required to complete the mirror initialization.
Workaround For mirrored drives that will not hold the bootable operating system, create the
RAID 1 configuration at the operating system level or use an Intel based RAID
card for better performance. For mirrored drives that will hold the bootable
operating system, configure the mirror using the CTRL-<C> bios utility and allow
enough time for the mirror to complete initialization before rebooting the
system. You will be limited to one RAID configuration per controller and you
can not create a RAID configuration across controller channels (cables). In other
words, if you have two onboard SCSI channels (cables) as with the I Intel®
server Board SE7520JR2 SCSI you will only be able to create one RAID (0 or 1)
configuration on one of the channels. For more details on the onboard controller
please refer to the "LSI Integrated RAID User's Guide" posted at

2 BIOS will display a warning message when the mBMC System Event
Log (SEL) is full
Description During boot, the BIOS may briefly display a red warning message indicating that
the System Event Log (SEL) is full. This message appears after multiple reboots,
due to the limited SEL storage space of the On-Board Platform Instrumentation.
The SEL storage space of the mBMC allows for the storage of 92 SEL entries. A
typical reboot add
the normal boot process.
Implication The red warning message displayed by the BIOS is not an error. It is a warning
message that the SEL is full and that no more system event messages can be
logged until the SEL is cleared.
Workaround The System Event Log (SEL) of the On-Board Platform Instrumentation should
be cleared regularly. There are several methods of clearing the SEL, including:
