|Transitioning From Oracle Solaris 10 to Oracle Solaris 11 Oracle Solaris 11 Information Library|
The Oracle Solaris 10 release uses the iSCSI target daemon and the iscsitadm command and the ZFS shareiscsi property to configure iSCSI LUNs.
In the Oracle Solaris 11 release, the COMSTAR (Common Multiprotocol SCSI Target) features provide the following components:
Support for different types of SCSI targets, not just the iSCSI protocol
ZFS volumes are used as backing store devices for SCSI targets by using one or more of COMSTAR's supported protocols.
Although the iSCSI target in COMSTAR is a functional replacement for the iSCSI target daemon, no upgrade or update path exist to convert your iSCSI LUNs to COMSTAR LUNs.
Both the iSCSI target daemon and the shareiscsiproperty are not available in Oracle Solaris 11. The following commands are used to manage iSCSI targets and LUNs.
The itadm command manages SCSI targets.
The srptadm command manages SCSI RDMA Protocol (SRP) target ports.
The stmfadm command manages SCSI LUNs. Rather than setting a special iSCSI property on the ZFS volume, create the volume and use stmfadm to create the LUN.
