port
B
--disable Disables the physical port, if currently enabled. This is a destructive operation
and affects normal operation of the port. The port is taken offline, all remote
FCP sessions are logged out, and all outstanding I/Os are terminated. You are
prompted before disabling occurs.
port_id Specifies the ID of the port you want to disable.
--stats Displays the physical port-level statistics.
port_id Specifies the ID of the port for which you want to display statistical
information.
--statsclr Clears port-level statistics.
port_id Specifies the ID of the port for which you want to clear statistical information.
--query Queries and displays port-related details for a port.
port_id Specifies the ID of the port for which you want to display information.
--speed Queries or sets the port speed. The port speed can be changed dynamically
(when the port is enabled). If the port is disabled, the new port speed setting
takes effect when the port is re-enabled.
port_id Specifies the ID of the port for which you want to set the port speed.
1|2|4|8|auto Specifies the port speed. Possible values are auto (to auto-negotiate the
speed) and 1, 2, 4, 8 speeds.
Note: The 1 Gbps speed is not valid for an 8 Gbps HBA (825, 815) and the 8
Gbps speed is not valid for a 4 Gbps HBA (425, 415). All speeds are valid for a
mezzanine card (804).
--dfsize Queries or sets the port’s maximum receive data field size. If you do not
specify a value, the current receive buffer size displays.
Note: The new receive data field size takes effect when the port is re-enabled.
port_id Specifies the ID of the port for which you want to set the data field size.
df_size Indicates the maximum supported receive data field size, in decimal value. If
set to auto, the driver default value displays. Possible values are 512, 1024,
2048, and 2112. If set to ‘auto,’ the default value is used, which is 2112.
--topology Queries or sets the port topology. The port topology can be changed
dynamically (when the port is enabled). If the port is disabled, the new
topology setting takes effect when the port is re-enabled.
port_id Specifies the ID of the port for which you want to display or set the topology.
auto|p2p Specifies the topology type. Supported topology modes are as follows:
• auto - auto-discovers the topology
• p2p - point-to-point
• loop - loop mode
Note: The topology setting will take effect after the port --disable and
port --enable commands are executed.
