If the target supports multiple sessions, you can create an additional session by clicking Add Session.
To disconnect individual sessions, select the session in the list, and then click Disconnect.
For more information about devices that are associated with a session, select the session, and then click Devices.
Multiple Connections per Session (MCS) support is defined in the iSCSI RFC to allow multiple TCP/IP connections from the initiator to the target for the same iSCSI session. This is iSCSI protocol specific. This allows I/O to be sent over either TCP/IP connection to the target. If one connection fails, another connection can continue processing I/O without interrupting the application. Note that not all iSCSI targets support MCS. iSCSI targets that support MCS include, but are not limited to, EMC Celerra, iStor, and Network Appliance.
