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.

Also note that FreeBSD currently supports two different initiators: the old one, iscsi_initiator(4), with its control utility iscontrol(8), and the new one, iscsi(4), with iscsictl and iscsid(8). The only thing the two have in common is the configuration file, iscsi.conf(5).

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

HISTORY

The iscsictl command appeared in FreeBSD 10.0.
