Driver Handle Table Column Definitions
Topology Information
Arbitrated Loop Operation
FC-AL (Loop) topology only is used. After successful loop initialization, the
driver attempts login with FL_PORT (switched fabric loop port).
If FL_PORT login is successful, public loop operation is entered.
If FL_PORT login is unsuccessful, private loop mode is entered.
Point-to-Point Operation
If F_PORT (point-to-point) login is successful, fabric mode is used.
If F_PORT login is unsuccessful, N_PORT-to-N_PORT direct connection
topology is used.
If a switch is discovered, the driver performs the following tasks:
FL_PORT login (FC-AL topology) or F_PORT login (Point-to-Point
topology).
Simple Name Server login.
State Change Registration.
Symbolic Name Registration.
FCP Type Registration if RegFcpType is set to 1.
Driver logs out and re-logs in. The name server indicates that registration is
complete.
Simple Name Server Query for devices (the registry parameter SnsAll
determines whether all N_PORTS are requested or only SCSI FCP
N_PORTS).
Discovery/device creation occurs for each target device described by the
name server.
Drv
The device driver handle number.
Version
The driver version.
Type
The device type. D indicates a device driver. B indicates a bus driver.
Cfg
If this column is marked with an X, the driver is supported by the
EFI utility (configuration protocol).
Diag
If this column is marked with an X, the driver is supported by the
EFI diagnostic protocol.
#D
The number of devices for the driver.
#C
The number of child devices for the driver (bus drivers only).
Driver Name and
Image Name
The driver and image name.
