NAME

iscsi-initiator -- refuse-based iSCSI initiator

SYNOPSIS

iscsi-initiator [-46bcDfVv] [-a authentication-type] [-d digest-type]
[-h target-hostname] [-p target-port-number]
[-t target-number] [-u username] mount_point

DESCRIPTION

The iscsi-initiator utility can be used to access an iSCSI target, such
as iscsi-target(8), to access block storage which has been exported.
Information pertaining to the target is displayed underneath the mount
point, along with the device corresponding to the storage which the tar-
get exports.

The various arguments are as follows:

-4 Use an IPv4 connection to the target.

-6 Use an IPv6 connection to the target.

-a authentication-type
Use the specified authentication type when communicating with the
target. The possible values are chap, kerberos, srp or none.
The default value is none.

-b Show the storage as a block device.

-c Show the storage as a character device.

-d digest-type
Use the specified digest type when communicating with the target.
The possible values are header, data, both, all or none. The
default value is none.

-D List the LUNs on the specified target and exit (i.e. do discovery
only)

-f Show the storage as a regular file.

-h hostname
Connect to the iSCSI target running on the host specified as the
argument.

-p port-number
Connect to the iSCSI target running on the port specified as the
argument. The default value is 3260.

-t target
Connect to the number of the iSCSI target running as the argu-
ment.

-u username
Use the specified user's credentials when logging in to the iSCSI
target. There is no default.

-V Print out the version number and then exit.

-v Be verbose in operation.

The refuse(3) library is used to provide the file system features.

The mandatory parameter is the local mount point.

This iSCSI initiator presents a view of the targets underneath the mount
point. Firstly, it creates a directory tree with the hostname of the
target, and, in that directory, a virtual directory is created for each
target name exported by the iSCSI target program. Within that virtual
target directory, symbolic links exist for the hostname (for conve-
nience), a textual representation of the IP address, the iSCSI target
product name, the iSCSI target IQN, the iSCSI target vendor and version
number. One other directory entry is presented in the virtual target
directory, relating to the storage presented by the iSCSI target. This
can be in the form of a regular file, which is also the default, a block
device or a character device.

Please note that the iscsi-initiator utility needs the ``puffs'' kernel
module loaded via modload(8) to operate.
