Abstract
A method for receiving a Mode Select command concerning a LUN from a host. The Mode Select command defines control information and host identifier information concerning the host associated with the Mode Select command. The Mode Select command is processed to determine if the control information included within the Mode Select command signifies an intent by the host to relinquish control of the LUN. If the control information signifies an intent to relinquish control of the LUN, the host identifier information included within the Mode Select command is processed to confirm that it matches LUN control identifier information that defines the host that currently controls the LUN. If the host identifier information matches the LUN control identifier information, at least the control information included within the Mode Select command is written to a buffer associated with the LUN. The buffer includes a control field and a GUID field.
