They are qualified by a date yyyy-mm because domain names can expire or be acquired by another entity. Isscsi maps to the endpoint of an iSCSI normal operational session.

A Network Portal in an initiator is identified by its IP address. Izcsi iSCSI name represents a worldwide unique naming scheme. All unqualified usages of “initiator” refer to an initiator port or device depending on the context. Storwize V offers single subnet multi-session configurations and multiple and dual subnet multisession configurations that remove issi restriction against logging in to a target name.

March Learn how and when to remove this template message. Login Request and Login Response. Although iSCSI can communicate with arbitrary types of SCSI devices, system administrators almost always use it to allow servers such as database servers to access disk volumes on storage arrays.

Timeouts on Planned Decommissioning. Across all connections within a session, an initiator sees one and the same target.

iSCSI overview

The host contains one or more initiators that attach to an IP network to initiate requests to and receive responses from an iSCSI target. Message Synchronization and Steering.

It is explicitly specified by the initiator during Login. Please help improve this section by adding citations to reliable sources. Definitions and Acronyms 2.

While iSCSI could be implemented as just a VLAN cluster of ports on a large multi-port switch that is also used for general network usage, the administrator may instead choose to use physically separate switches dedicated to iSCSI VLANs only, to further prevent the possibility of an incorrectly connected cable plugged into the wrong port bridging the logical barrier.

The TargetPortalGroupTag key must also be returned by the target as a confirmation during connection establishment when TargetName is given.
