Clear Log Buffer
The Intel RAID Controller SRCU32 records certain events in a logging buffer which is part of the
Flash-RAM. Clear all events in the buffer when using the Intel RAID Controller SRCU32 in a new
system. The Clear Log Buffer function detects and deletes entries from the log buffer.
Configure Physical Devices
This menu option displays a list of I/O channels (SCSI or Fibre Channel) and available devices.
See Figure 43.
Scroll the list with the cursor up/down keys. The first column displays the I/O channel (“SCSI”
stands for SCSI and “FCAL” for Fibre-Channel). The next column shows the ID followed by the
LUN (Logical Unit Number; normally always 0). The next column is either filled with a lowercase
“i” (for initialized), or empty. Initialization means the creation of Intel RAID Controller
SRCU32-specific configuration data on the hard drives and the adjustment of hard drive specific
operating parameters (protocol, transfer rate, etc.). The next entry lists the vendor and type of
device, followed by the drive’s attributes (RW for Read/Write; RO for Read Only). The I/O
processors and SAF-TE processors (in our example channel B ID 8: SDR, Inc. GEM312 REV001)
to not have attributes. The next column lists the capacity of the hard drive in MB
(1 MB = 1024 KB; 1 GB=1024 MB). The last column gives information on the assignment of this
physical device to a logical/array/host drive.

Keyboard Commands
With Intel RAID Controller SRCU32 Fibre Channel RAID Controllers, <F4> delivers extended
information on Fibre Channel drives (World Wide Name, firmware-level, and the Link-status of
the drive).
By pressing <F5> the Intel RAID Controller SRCU32 periodically turns the LED (if available) of
the corresponding drive on and off. This helps to physically identify a specific drive in an array of
many drives.
By pressing <F8> you can repair the configuration data of a physical drive. If the Intel RAID
Controller SRCU32 should ever display during the boot sequence a message like “Detected
Primary Configuration Data error, using Secondary,” you can try to repair the data by
pressing <F8>.
