Changing a Server Assignment

Selecting a Server to Manage a Controller

When you assign a server to manage a controller, information regarding the managing server is produced. SANscape stores this information on a controller and uses it to keep track of the managing server. In the event a server is shut down, for maintenance for example, and you try to assign another server to manage the controller, SANscape reads the stored server information from the controller and warns you that the controller is being managed already.

NOTE: You can override the current server assignment if you want to force a new server assignment.

View the managing server name using the firmware application menu view and edit Host luns > Edit Host-ID/WWN Name List.

If you want to change a server assignment, for example, because you are moving an array to a new location, before you move the array, you need to unassign the managing server following the steps in To Unassign the Managing Server.

If you have already moved the array, when the array starts up, you might see the warning message that the controller is already being managed by another server. You need to manually delete the server following the steps in To Manually Delete a Server Using the Terminal Window. Refer to the SANnet II RAID Firmware User's Guide for your array for information about accessing the firmware application.
