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 log in again 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
device. The default is 30 retries for Microsoft Windows Operating System
environment. Please review the device driver README for the correct
setting in other operating system environments.
Port Down Retry Count
This setting specifies the number of seconds that the software waits before
it retries a command to a port returning port down status. The default is 30
seconds. In a DS4000 storage server configuration with the maximum
number of drive expansion enclosures or in MCSC configurations, you
should increase this setting to 70.
Link Down Timeout
This setting specifies the number of seconds the software that the software
waits for a link down to come up. The default is 30 seconds.
Extended Error Logging
This setting provides additional error and debug information to the operating
system. When enabled, events are logged into the Windows Event Viewer.
The default is Disabled.
Operation Mode
This setting specifies the reduced interrupt operation (RIO) modes, if
supported by the software driver. RIO modes allow posting multiple
command completions in a single interrupt. The default is 0.
Interrupt Delay Timer
This setting contains the value (in 100-microsecond increments) that is
used by a timer to set the wait time between accessing (DMA) a set of
handles and generating an interrupt. The default is 0.
Selectable boot settings
When you set the Selectable Boot Settings option to Enabled, you can select the
worldwide port name of the fibre-channel hard disk from which you want to start up
(boot). When this option is set to Enabled, the node starts from the selected
fibre-channel hard disk, ignoring any IDE or SCSI hard disks that are attached to
your server. When this option is set to Disabled, the Boot ID and Boot LUN
parameters have no effect.
The BIOS code in some new systems supports selectable start up, which
supersedes the Fast!UTIL selectable start up setting. To start from a fibre-channel
