The Configuration WWN is what is reported to the outside world no matter
what port you are plugged into. This way if you swap controllers (because
of a failure), your Configuration WWN still reports the same WWN as it did
before, so you do not have to change any mappings on your host or fibre
channel switch.
If another controller was used to create the configuration, its WWN is
displayed. You should assign the configuration WWN to the installed
controller. In this case click
Controller 0 or Controller 1 , then click APPLY
and restart StorView.
■
Controller LUN - This option lets you set a specific LUN number or disable
the controller LUN. By default the controller LUN is automatically assigned
the next LUN number after the last logical drive.
If your operating system is having a problem displaying the controller LUN,
click the pull-down selection and select
Disabled .
■
Different Node Name - Selecting this option lets the controller report a
different Configuration WWN for Port 0 and Port 1 (Host 0 and Host 1, or
H0 and H1 connectors on the controllers). Normally, when deselected, a
host connected to either port sees the same Configuration WWN.
When enabled (selected), you see a slightly different WWN for each port
but the same Configuration name. This option is useful if you are
connecting the storage solution to a switch employing a fabric topology
where the same WWN is not tolerated.
Fault tolerance
In the Fault Tolerance section, you can enable or disable controller features that
improve the controller’s ability to maintain a level of fault tolerance.
