SANsurfer FC HBA Manager
SANsurfer FC HBA Manager displays target devices on an HBA, loop topology
information, loop error count information, etc. SANsurfer FC HBA Manager displays
target devices on an HBA and is useful for analyzing system configurations.
SANsurfer FC HBA Manager uses a feature of the enhanced miniport driver to find
and display information about devices that are not configured on the local host. This
feature can display information about all potential target devices on a fabric or all
devices on a loop topology, not just those that are configured on the local host.

Known Issues
2.4.2.1
ConfigRequired Parameter
To maintain backward compatibility with previous versions, if the configuration
cannot be read from the registry, the miniport driver defaults to the previous
operation of configuring and enabling all devices that are found. Some OEMs
indicate that this is an unacceptable risk when adding a new host to a SAN system
and that the desired operation is to configure
no devices instead of all devices. A
new parameter was added to miniport registry parameters to indicate that
configuration is required. Find this parameter in special OEM setup files in one of
the following strings, depending on the type of miniport driver:
HKLM\System\CurrentControlSet\Services\ql2200\
Parameters\Devices\DriverParameters
HKLM\System\CurrentControlSet\Services\ql2300\
Parameters\Devices\DriverParameters
The parameter value is ConfigRequired=0 (FALSE) or ConfigRequired=1 (TRUE).
If the parameter is not found, the default value is ConfigRequired=0. Note that this
parameter is used only when configuration information cannot be read from the
persistent storage.
