Solaris Express 6/05: iSCSI is an Internet Protocol (IP)-based storage networking standard for linking data storage subsystems. By carrying SCSI commands over IP networks, the iSCSI protocol enables you to mount disk devices, from across the network, onto your local system. On your local system, you can use the devices like block devices.
For more information, see Chapter 14, Configuring Solaris iSCSI Targets and Initiators (Tasks).
Solaris Express 3/06: The following enhancements have been added to the Solaris iSCSI initiator support:
Dynamic target removal support – Provides the ability to remove (or log out) an iSCSI target without rebooting the system. If you try to remove or disable a discovery method or address, and the target is not in use, the target is removed and related resources are released. If the target is in use, the discovery address or method remains enabled, and in use message is displayed.
For more information, see How to Remove Discovered iSCSI Targets.
Internet Storage Name Service (iSNS) client support – Enables the iSCSI initiator to discover the targets to which it has access using as little configuration as possible. It also provides state change notification functionality to notify the iSCSI initiator when changes in operational state of storage nodes occur. The iscsiadm command has been enhanced to support iSNS discovery.
For more information, see How to Configure iSCSI Target Discovery.
Multiple session target (MS/T) support – Provides the ability to create more iSCSI sessions or paths to a target on demand. The additional iSCSI paths provide higher bandwidth aggregation and availability in specific configurations, such as iSCSI arrays that support login redirection. The iSCSI MS/T feature should be used in combination with MPxIO or other multipathing software. The iscsiadm command has been enhanced to support MS/T.
