The iscsi driver is a software initiator that transports SCSI commands over TCP/IP as described in RFC 3720.
The initiator driver is administered through iscsiadm(1M). The iscsi initiator service is managed by the service management facility, smf(5), under the following FMRI:
The iscsi initiator acts as a host adapter driver that attaches the appropriate target driver, for example, sd(7D) for disks, or st(7D) for tapes) for devices it discovers. See the System Administration Guide: Devices and File Systems for more information.
Once enabled, the iscsi initiator service ensures the right timing to start the discovery and enumeration of iSCSI devices during boot, but it doesn't guarantee the success of discovery for certain iSCSI devices. If the service is disabled, iscsi driver stops the discovery and enumeration of iSCSI devices and also tries to offline all existing iSCSI devices. iscsiadm(1M) works only when the service is enabled.
iSCSI boot(1M) is not affected by the status of the iscsi initiator service.
