iSCSI Logout Support

This system administration feature is new in the Solaris 10 6/06 release.

The iSCSI logout support feature allows a user to logout from an iSCSI target without rebooting the host. When a user tries to remove or disable a discovery method or address and the target is not in use, then the target logs out and cleans up all related resources. If the target is in use, then the discovery address or method remains enabled and the logical unit in use message is logged. This feature introduces a new behavior to safely log out of unused devices without rebooting the host.

The following commands can be use to apply this feature:

• iscsiadm modify discovery -[tsi] disable

• iscsiadm remove discovery-address

• iscsiadm remove static-config

• iscsiadm remove isns-server

A user is no longer required to reboot a host when an attached iSCSI storage is removed from the host.

For further information, see the iscsiadm(1M) man page. See also the System Administration Guide: Devices and File Systems.
