Name

ocf_heartbeat_iSCSITarget — iSCSI target export agent

Synopsis

iSCSITarget [ start | stop | monitor | meta-data | validate-all ]

Description

Manages iSCSI targets. An iSCSI target is a collection of SCSI Logical Units (LUs) exported via a daemon that speaks the iSCSI protocol.

Supported Parameters

implementation

The iSCSI target daemon implementation. Must be one of "iet", "tgt", or "lio". If unspecified, an implementation is selected based on the availability of management utilities, with "iet" being tried first, then "tgt", then "lio". (optional, string, no default)

iqn

The target iSCSI Qualified Name (IQN). Should follow the conventional "iqn.yyyy-mm.<reversed domain name>[:identifier]" syntax. (required, string, no default)

tid

The iSCSI target ID. Required for tgt. (optional, integer, no default)

portals

iSCSI network portal addresses. Not supported by all implementations. If unset, the default is to create one portal that listens on . (optional, string, default 0.0.0.0:3260)

allowed_initiators

Allowed initiators. A space-separated list of initiators allowed to connect to this target. Initiators may be listed in any syntax the target implementation allows. If this parameter is empty or not set, access to this target will be allowed from any initiator. (optional, string, no default)

incoming_username

A username used for incoming initiator authentication. If unspecified, allowed initiators will be able to log in without authentication. This is a unique parameter, as it not allowed to re-use a single username across multiple target instances. (optional, string, no default)

incoming_password

A password used for incoming initiator authentication. (optional, string, no default)

additional_parameters

Additional target parameters. A space-separated list of "name=value" pairs which will be passed through to the iSCSI daemon's management interface. The supported parameters are implementation dependent. Neither the name nor the value may contain whitespace. (optional, string, no default)

start

Starts the resource. Suggested minimum timeout: 10.

stop

Stops the resource. Suggested minimum timeout: 10.

status

Suggested minimum timeout: 10. Suggested interval: 10.

monitor
