NAME
iscsictl - iSCSI initiator management utility

SYNOPSIS
iscsictl -A -p portal -t target [-u user -s secret] [-w timeout] [-r] [-e on|off]
iscsictl -A -d discovery-host [-u user -s secret] [-r] [-e on|off]
iscsictl -A -a [-c path]
iscsictl -A -n nickname [-c path]
iscsictl -M -i session-id [-p portal] [-t target] [-u user] [-s secret] [-e on|off]
iscsictl -M -i session-id [-n nickname [-c path]]
iscsictl -R [-p portal] [-t target]
iscsictl -R -a
iscsictl -R -n nickname [-c path]
iscsictl -L [-v] [-w timeout]

DESCRIPTION
The iscsictl utility is used to configure the iSCSI initiator.

The following options are available:

--libxo
    Generate output via libxo(3) in a selection of different human and machine readable formats. See xo_parse_args(3) for details on command line arguments.

-A  Add session.

-M  Modify session.

-R  Remove session.

-L  List sessions.

-a  When adding, add all sessions defined in the configuration file. When removing, remove all currently established sessions.

-c path
    Path to the configuration file. The default is /etc/iscsi.conf.

-d discovery-host
    Target host name or address used for SendTargets discovery. When used, it will add a temporary discovery session. After discovery is done, sessions will be added for each discovered target, and the temporary discovery session will be removed.

-e on|off
    Enable or disable the session. This is ignored for discovery sessions, but gets passed down to normal sessions they add.

-i session-id
    Session ID, as displayed by iscsictl -v.

-n nickname
    The nickname of a session defined in the configuration file.

-p portal
    Target portal — host name or address — for statically defined targets.

-r  Use iSER (iSCSI over RDMA) instead of plain iSCSI over TCP/IP.

-s secret
    CHAP secret.

-t target
    Target name.

-u user
    CHAP login.

-v  Verbose mode.

-w timeout
    Instead of returning immediately, wait up to timeout seconds until all configured sessions are successfully established.

Certain parameters are necessary when adding a session. One can specify these either via command line (using the -t, -p, -u, and -s options), or configuration file (using the -a or -n options). Some functionality - for example mutual CHAP - is available only via configuration file.

Since connecting to the target is performed in background, non-zero exit status does not mean that the session was successfully established. Use either iscsictl -L to check the connection status, or the -w flag to wait for session establishment.

Note that in order for the iSCSI initiator to be able to connect to a target, the iscsid(8) daemon must be running.

FILES
/etc/iscsi.conf
    iSCSI initiator configuration file.

EXIT STATUS
The iscsictl utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
Attach to target iqn.2012-06.com.example:target0, served by 192.168.1.1:
    iscsictl -A -t iqn.2012-06.com.example:target0 -p 192.168.1.1

Perform discovery on 192.168.1.1, and add disabled sessions for each discovered target; use -M -e on to connect them:
    iscsictl -A -d 192.168.1.1 -e off

Disconnect all iSCSI sessions:
    iscsictl -Ra
