Spin up delay
When this bit is set, the BIOS will wait up to 5 minutes to find the first drive.
The default setting is Disabled.
Connection Options
This setting defines the type of connection (loop or point to point) or
connection preference. The default is 2.
Fibre Channel Tape Support
This setting enables FCP-2 recovery. The default is Enabled. You should
change this setting to Disabled if the HBA is connected to a DS4000
storage server. The DS4000 storage server does not support a tape device
through the same Fibre-Channel HBA from the host server.
Data Rate
This setting determines the data rate. When this setting is 0, the FC2-133
HBA runs at 1 gbps. When this setting is 1, the FC2-133 HBA runs at 2
gbps. When this setting is 2, Fast!UTIL determines what rate your system
can accommodate and sets the rate accordingly. The default is 2
(auto-configure).
Access the following advanced host bus adapter settings through the Configuration
Settings menu in Fast!UTIL and select Advanced Adapter Settings. The default
settings for the FC2-133 HBA are as follows:
Execution Throttle
This setting specifies the maximum number of commands executing on any
one port. When the execution throttle of a port is reached, no new
commands are executed until the current command finishes executing. The
valid options for this setting are 1-256. The default is 255.
LUNs per Target
This setting specifies the number of LUNs per target. Multiple LUN support
is typically for redundant array of independent disks (RAID) boxes that use
LUNs to map drives. The default is 0. For host operating systems other
than Microsoft Windows, one may need to change this setting to a value
other 0 to allow the host to see more than one logical drive from the
DS4000 Storage Server. Review the device driver README for the
appropriate setting for environments other than Microsoft Windows
Operating System.
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
setting is Yes, the driver initiates a global LIP reset to clear the target
device reservations. When this setting is No, the driver initiates a global LIP
reset with full login. The default is No.
Enable LIP Full Login
This setting instructs the ISP chip to re-login to all ports after any LIP. The
default is Yes.
Enable Target Reset
This setting enables the drivers to issue a Target Reset command to all
devices on the loop when a SCSI Bus Reset command is issued. The
default is Yes.
Login Retry Count
This setting specifies the number of times the software tries to log in to a
