emlxadm>

At the bottom of the command list is an emlxadm> prompt. From this point, the utility is prompt driven. 
When the prompt is displayed, you must enter one of the commands in the list. The list is displayed 
automatically only once, but you can display it again by entering h at the prompt. To exit the program, 
enter q.

Some commands require additional arguments, such as a Fibre Channel World Wide Port Name 
(WWPN) or a Fibre Channel port address (D_ID). To display the available arguments for a command, 
enter the command without any arguments.

For example, the command get_state requires a WWPN for the target device. If only the command 
without the argument is entered, the following statement appears to indicate that the command requires 
an argument to be executed. For example:

emlxadm> get_state

Usage: get_state <wwpn>

emlxadm> get_state 21000020371938fa

State: PORT_DEVICE_LOGGED_IN

For a detailed explanation of each command and its arguments, see 

The emlxadm utility program can be run in CLI mode by typing the name of the program, followed by the 
full device name of the desired HBA, followed by a valid command and any required command 
arguments. For example:

# emlxadm /devices/pci@1e,600000/SUNW,emlxs@2/fp@0,0:devctl get_state 
21000020371938fa

State: PORT_DEVICE_LOGGED_IN

#

This mode of operation enables you to use the emlxadm utility as part of a script or another program 
capable of executing system level calls. For a detailed explanation of each command and its arguments, 
see 

This section provides a list of commands that can be issued with the emlxadm utility program.
