You need to configure the iSCSI initiator to discover the target so that the host can access LUNs on the target. The method you use to do this depends on your version of the operating system.
The following sections provide instructions for setting up targets on Red Hat Enterprise Linux 5, 6, and 7 series; Red Hat Enterprise Linux 4 series; and SUSE Linux Enterprise Server 10, 11, and 12 series. If you are using SUSE Linux Enterprise Server 9 series, see Recommended Host Settings for Linux Unified Host Utilities 7.0 at mysupport.netapp.com.
