4. To end the session:
a. Select the session that you want to end, and then click End Session.
The End Session confirmation window is displayed.
b. Click Yes to confirm that you want to end the iSCSI session.
NOTE: If you end a session, any corresponding connections terminate the link between the host and the storage
array, and the data on the storage array is no longer available.
NOTE: When a session is manually terminated using the MD Storage Manager, the iSCSI initiator software
automatically attempts to re-establish the terminated connection to the storage array. This may cause an error
message.
