NAME fcoeadm - The Open-FCoE Administration Tool
SYNOPSIS fcoeadm -c|--create ethX
fcoeadm -d|--destroy ethX
fcoeadm -r|--reset ethX
fcoeadm -i|--interface [ethX]
fcoeadm -t|--target [ethX]
fcoeadm -l|--lun [ethX]
fcoeadm -s|--stats ethX [interval]
DESCRIPTION The fcoeadm utility is the Fibre Channel over Ethernet (FCoE) management tool for the Open-FCoE project. fcoeadm may be used to create, destroy, and reset an FCoE instance on a given network interface. For these operations fcoeadm sends a command to a running fcoemon process, via a socket interface. fcoemon will then perform the requested operation.
fcoeadm also provides options to query information about FCoE instances, including interface information, target information, LUN information, and port statistics. For much of this information, fcoeadm relies on the libhbalinux implementation of the HBA API.
OPTIONS -c, --create ethX Creates an FCoE instance based on the specified network interface. Note that if there is not an fcoemon configuration file for the interface (/etc/fcoe/cfg-ethX, see fcoemon), then the created FCoE instance will not require DCB.
-d, --destroy ethX Destroys the FCoE instance on the specified network interface.
-r, --reset ethX Resets the FCoE instance on the specified network interface.
-i, --interface [ethX] Show information about the FCoE instance on the specified network interface, or all FCoE instances if no network interface is specified.
-t, --target [ethX] Show information about the discovered targets associated with the FCoE instance on the specified network interface. If no network interface is specified, information about discovered targets from all FCoE instances will be shown.
-l, --lun [ethX] Show detailed information about the discovered SCSI LUNs associated with the FCoE instance on the specified network interface. If no network interface is specified, information about SCSI LUNs from all FCoE instances will be shown.
-s, --stats ethX [interval] Show the statistics (including FC4 statistics) of the FCoE interface on the specified network interface. The information will be display in one line on the screen per given time interval. interval should be specified in whole integers greater than 0. It specifies the time interval in the unit of seconds. If interval is not specified, the default interval is one second.
-h, --help Displays the usage message of the fcoeadm command.
-v, --version Displays the version of the fcoeadm command.
EXAMPLES Creates an FCoE instance on eth2.101
fcoeadm -c eth2.101
Destroys the FCoE instance on eth2.101
fcoeadm -d eth2.101
Resets the FCoE instance on eth2.101
fcoeadm -r eth2.101
Show the information of all the adapters and their ports having FCoE instances created
Show the information of a specific interface eth3. If eth3 has no FCoE instances created, the command will show the error "No fc_host found for eth3"
fcoeadm -i eth3
Show the information of all the discovered targets from all the ports having FCoE instances created (they may be on different adapter cards). A brief listing of discovered LUNs are listed after the target they are associated with, if any
Show the information of all the discovered targets from a given port (eth3) having FCoE instance created. A brief listing of discovered LUNs are listed after each target they are associated with, if any
fcoeadm -t eth3
Show the detailed information of all the LUNs discovered on all FCoE connections
Show the detailed information of all the LUNs associated with a specific interface
fcoeadm -l eth3.101
Show the statistics information of a specific port eth3 having FCoE instances created. The statistics are displayed one line per time interval. The default interval is one second if an interval is not specified
fcoeadm -s eth3
fcoeadm -s eth3 3
