12 Intel® Blade Server Fibre Channel Expansion Card SBEFCM4, 4 Gbps: Installation and User’s Guide
Advanced adapter settings
Use this option to view and set advanced adapter settings. The default settings for the Fibre Channel
Expansion Card are listed in Table 6 on page 12 and are described in this section.
Execution throttle: This setting specifies the maximum number of commands that can run on any
one port. When a port reaches its execution throttle, Fast!UTIL does not run any new commands
until the current command is completed. The valid options for this setting are 1 through 256.
LUNs per target: This setting specifies the number of logical unit numbers (LUNs) per device.
Multiple LUN support is typically for redundant array of independent disks (RAID) enclosures that
use LUNs to map drives.
Enable LIP reset: This setting determines the type of loop initialization process (LIP) reset that is
used when the operating system initiates a bus reset routine. When this option is set to Yes, the
device driver initiates a global LIP reset to clear the target device reservations. When this option is
set to No, the device driver initiates a global LIP reset with full login.
Enable LIP full logon: This setting instructs the application specific integrated circuit (ASIC) chip
to log in to all ports after any LIP.
Enable target reset: This setting enables the device drivers to issue a Target Reset command to all
devices on the loop when a SCSI Bus Reset command is issued.
Login retry count: This setting specifies the number of times the software tries to log in to a device.
Port down retry count: This setting specifies the number of times the software retries a command
to a port that is returning port-down status.
IOCB allocation: This setting specifies the maximum number of buffers from the firmware buffer
pool that are allocated to any one port.
Extended error logging: When set to Enabled, this setting provides additional error and
debugging information to the Microsoft Windows* operating system event error log.
