For Microsoft Windows Server 2003, each list contains all available host IP addresses regardless of whether or not the address is able to communicate with the associated iSCSI port. You must select the appropriate host IP addresses for each iSCSI port. Automatic Selection NOTE: The contents in this section do not apply to Microsoft Windows Server 2003. The utility attempts to automatically find and select the best possible configuration of host IP address(es) and storage array iSCSI ports for optimal performance and redundancy. This automatic selection attempts to ensure that a host IP address (up to two IP addresses for MD3000i storage arrays and up to four IP addresses for MD3200i and MD3220i storage arrays) establishes an iSCSI session with each storage array controller and that the host IP address is logged into a maximum of one iSCSI port per controller. Configuration in this manner ensures redundancy and load balancing among the multiple host IP addresses (NICs). The Do Not Connect option may be selected as the default option if the utility recommends not to connect to the iSCSI port. Also, even if the best recommended configuration is presented (whenever possible), you can still override this configuration by selecting the other host IP addresses from the drop-down list. Suboptimal Configuration Warnings In the following cases, a warning is displayed, that you must confirm, to continue: • The host IP addresses are selected in such a way that any host IP address establishes an iSCSI session with only one storage array controller in a dual controller (duplex) configuration. • The host IP addresses are selected in such a way that a host IP address establishes two or more iSCSI sessions with the same storage array controller.

For Microsoft Windows Server 2003, each list contains all available host IP
addresses regardless of whether or not the address is able to communicate
with the associated iSCSI port. You must select the appropriate host IP
addresses for each iSCSI port.
Automatic Selection
NOTE:
The contents in this section do not apply to Microsoft Windows Server 2003.
The utility attempts to automatically find and select the best possible
configuration of host IP address(es) and storage array iSCSI ports for optimal
performance and redundancy.
This automatic selection attempts to ensure that a host IP address (up to two
IP addresses for MD3000i storage arrays and up to four IP addresses for
MD3200i and MD3220i storage arrays) establishes an iSCSI session with each
storage array controller and that the host IP address is logged into a maximum
of one iSCSI port per controller. Configuration in this manner ensures
redundancy and load balancing among the multiple host IP addresses (NICs).
The
Do Not Connect
option may be selected as the default option if the
utility recommends not to connect to the iSCSI port. Also, even if the best
recommended configuration is presented (whenever possible), you can still
override this configuration by selecting the other host IP addresses from the
drop-down list.
Suboptimal Configuration Warnings
In the following cases, a warning is displayed, that you must confirm, to
continue:
•
The host IP addresses are selected in such a way that any host IP address
establishes an iSCSI session with only one storage array controller in a dual
controller (duplex) configuration.
•
The host IP addresses are selected in such a way that a host IP address
establishes two or more iSCSI sessions with the same storage array
controller.
