The following describe the components of the Identity section:
• Configuration Name - This is the name you will assign to the configuration. The configuration
contains all the information that defines the disk arrays, logical drives, SAN LUN Mapping, hot spare
drives and controller specific settings.
If you wish to change the configuration name, enter the new name in the block provided. Click the
APPLY button followed by the CLOSE button.
• Configuration WWN - This is the RAID Controller’s WWN reported to the outside world to identify
the StorView configuration.
If a new WWN is showing up in the list, it is possible for you to have a configuration WWN on your
system where there is not a controller in the storage system with the same WWN. For example: if
you have one or two controllers in your system with no configuration. Note there is no WWN in the
Configuration WWN select box, only Controller 0/1. Then create an array. Then pull out Controller
0. (If you only had a single controller in the system then insert another physical controller. If you have
dual controllers then just leave Controller 1 in there. Now go back and look at your Configuration
WWN you will notice a different WWN for the configuration then the controller’s WWN. The user can
only set the Configuration WWN to Controller 0 or Controller 1’s WWN. But if there is a stale WWN
then it will show it in the list indicating to the user what it is currently set to. The Configuration WWN
is what is reported to the outside world no matter what port you are plugged into the system. This
way if you swap controllers (most likely because of a failure) your Configuration WWN will still report
the same WWN as it did before so you will 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 the pull-down menu and select
Controller 0 or Controller 1. Click
APPLY and restart the StorView.
Important If you are using the Snapshot feature, your feature license key is based on the
Configuration WWN which is based on the RAID Controller’s WWN used at the time
of licensing. If you modify the Configuration WWN, the feature license key will no
longer be valid and the snapshot function (feature) will be disabled.
• Controller LUN - This option allows the user to 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.
In the event you have an operating system that is having a problem with the Controller LUN being
displayed, click the pull-down selection and choose “Disabled.”
• Different Node Name - Selecting this option allows the controller to report a different Configuration
WWN for Port 0 and Port 1 (Host 0 and Host 1 connectors). Normally, when deselected, a host
connected to either port will see the same Configuration WWN.
When enabled (selected) you will see a slightly different WWN for each port but the same
Configuration name. This option is useful to users who are connecting the storage to a switch
employing a fabric topology where the same WWN is not tolerated.
