iscsi_config is a tool to specify iSCSI targets to the kernel 
initiator and initiate iSCSI protocol operations. 

iscsi_config is invoked with at least one mandatory argument and
five optional arguments as given below. 

+--------------------------------------------------------------+
| iscsi_config <what-to-do> [host=number] [ip=address_or_name] |
|					[port=number] [target=number] [lun=number] |
+--------------------------------------------------------------+

+------------+
| what-to-do |
+------------+
	what-to-do determines whether an iSCSI session has to be 
	established between an iSCSI initiator and an iSCSI target
	or whether an existing iSCSI session needs to be closed.
	It can be one of the following:

		"up" 	an iSCSI session needs to be established.
		"down"	an iSCSI session needs to be closed.


+-------------+
| host=number |
+-------------+
    This is an optional field. If omitted assumes a value of 0.
    Format is
            host=<number>

    This specifies the SCSI Adapter number assigned by the kernel 
	to the iSCSI initiator.

+--------------------+
| ip=address_or_name |
+--------------------+
	This is an optional field that specifies the IP address of the
	iSCSI target to which a connection has to be established. If 
	omitted assumes the local IP address.

	Format is
			ip=name  (or) ip=address
	where 
		"name" is the hostname of the machine in which the iSCSI 
		target is waiting for requests from the iSCSI initiator.
		address is the IP address in dotted decimal notation.
	
+-------------+
| port=number |
+-------------+
	This is an optional field that specifies the port on which the 
	iSCSI target is listening. If omitted assumes the port number 
	of 4000.

+-------------+
| target=number |
+-------------+
	This is an optional field that specifies the target number
	(id number in hierarchical addressing scheme for Linux SCSI 
	 devices) for the target that the initiator is connecting to.
