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, 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 60 seconds.
Extended Error Logging
This setting provides additional error and debug information to the operating
system. When enabled, events are logged into the Windows NT 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.
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
hard disk that is attached to the DS4000 FC2-133, select the attached fibre-channel
hard disk from the system BIOS menu.
Note: The Selectable Boot Settings option for the DS4000 FC2-133 applies to only
fibre-channel hard disk drives.
You can use the Restore Default Settings option to restore the DS4000 FC2-133
default settings and NVRAM.
The default NVRAM settings are the adapter settings that were saved the last time
an NOVRAM update operation was run from the BIOS Update Utility program
(option U or command line /U switch). If the BIOS Update Utility program has not
been used to update the default NOVRAM settings since the adapter was installed,
the factory settings are loaded.
