ISCSI-INITIATOR(8)      NetBSD System Manager's Manual      ISCSI-INITIATOR(8)

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.

HISTORY
     The iscsi-initiator utility first appeared in NetBSD 6.0.  An earlier
     version called iscsifs was available in NetBSD 5.0 in source format only.

AUTHORS
     The iscsi-initiator utility was written by Alistair Crooks
     <agc@NetBSD.org>.

BUGS
     iscsi-initiator currently only supports a CHAP challenge length of 16
     octets.  Other initiators support up to 1024 and thus it is expected that
     most targets will also support such lengths.  This means that CHAP com-
     patibility with other targets apart from iscsi-target(8) is likely to be
     poor.  To workaround this, please use authentication type none by not
     specifying a username with the -u option.
