This device management feature is new in the Solaris 10 6/06 release.
The Internet Storage Name Service (iSNS) client feature adds a new discovery option to the Solaris OS iSCSI software initiator. This option enables user to use iSNs to handle Internet Protocol (IP)-SAN device discovery. This feature is off by default and is not a platform-specific feature. The iSNS client feature introduces several iscsiadm command additions, modifications, and driver changes to handle iSNS discovery.
IT customers who use iSCSI to build block-based IP-SAN need a scalable way to manage device discovery and configuration for their SANs as they grow. The iSNS client feature supports a scalable method for device discovery in a large IP-SAN configuration that uses a minimal configuration.
For further information about the new and modified command-line options, see the iscsiadm(1M) man page. See also the System Administration Guide: Devices and File Systems.
