Fast!UTIL

Each host adapter has a unique serial number. Write down the serial number of the Netfinity Fibre Channel PCI Adapter in the event that the nonvolatile random access memory (NVRAM) is damaged (see Scan Fibre Channel Devices). If the NVRAM is damaged, you will be prompted for the PCI adapter serial number.

Fast!UTIL Options: The following section describes the Fast!UTIL options.

Configuration Settings: The first selection on the Fast!UTIL Options menu is Configuration Settings. These settings configure the FC devices and the PCI adapter to which they are attached.

Host Adapter Settings: From the Configuration Settings menu in Fast!UTIL, select Host Adapter Settings. The current default settings for the host adapter are listed in following table and described in the following paragraphs.

NOTE: The host adapter settings and default values will vary based on the version of BIOS code installed for the adapter.

•  Host adapter BIOS: When this setting is disabled, the ROM BIOS on the  Netfinity Fibre Channel PCI Adapter is disabled, freeing space in upper memory.
   The default is Disabled.
•  Enable LUNs: When this setting is yes, multiple logical unit numbers (LUNs) are supported.  When this setting is no, multiple LUNs are not supported. LUN support is typically required for CD-ROM  changers or redundant array of independent disks (RAID) boxes that use LUNs to map drives.
   The default is Yes.
•  Execution throttle: This setting specifies the maximum number of commands executing on any  one port. When a port's execution throttle is reached, no new commands are executed until the current  command finishes executing. The valid options for this setting are: 1, 4, 8, 16, 32, 64, 128, and 255.
   The default is 255.
•  Drivers load RISC code: When this setting is enabled, the host adapter uses the RISC firmware  that is embedded in the device driver. When this setting is disabled, the device driver loads the latest  version of RISC firmware found on the system.
   The default is Enabled.

  NOTE: In order for the embedded device driver software to be loaded,  the driver being loaded must support this setting.
   If the driver does not support this setting, the result is the same as if the setting were disabled,  regardless of the setting.
   Leaving this option enabled guaranties a certified combination of software driver and RISC firmware.

•  Frame size: This setting specifies the maximum frame length supported by the Netfinity Fibre Channel  PCI Adapter.
   The default size is 2048.
•  IOCB allocation: This setting specifies the maximum number of buffers from the firmware  buffer pool that are allocated to any one port.
   The default is 256 buffers.
•  Loop reset delay: After resetting the loops, the firmware refrains from initiating any loop activity  for the number of seconds specified in this setting.
   The default is 5 seconds.
•  Extended error logging: This setting provides additional error and debug information to the  operating system.
   The default is Disabled.
•  Port down retry count: This setting specifies the number of times the software retries a command to a  port returning port down status.
   The default is 0 retries.
