To replace an interface controller:
CAUTION: If you need to replace an interface controller, refer to the appropriate library and
interface controller documentation for information on how to replace the hardware. Some interface
controllers are hot-pluggable. Refer to the interface controller documentation to see if your interface
controller is hot-pluggable.
1. Follow the instructions in the interface controller's replacement poster to remove and replace
the card.
CAUTION: You must connect the cables to the new interface controller exactly as they were
connected to the original interface controller. If you don't, the Interface Manager card will
not be able to reapply the settings.
2. In the Library window, click the Support tab.
3. In the left panel, select Hardware Replacement.
4. Select Actions
→Launch Interface Controller Replacement Wizard.
5. Follow the instructions in the wizard.
6. Verify that the firmware revision in the Interface Controller does not need to be upgraded.
Clearing a WWN mismatch
Beginning with version 1.7, the Interface Manager card claims “ownership” of the interface
controllers installed in a library. The MAC address of the Interface Manager card is stored in the
memory of each interface controller, creating an association between the Interface Manager card
and the interface controllers. If an interface controller that was “owned” by an Interface Manager
card is transferred from one library to another, then the Interface Manager card in the new library
will detect a WWN mismatch. To clear this situation, and to associate the interface controller with
the current Interface Manager card:
1.
In the Library window, click the Support tab.
2. In the left panel, select Hardware Replacement.
3. Select Actions
→Clear WWN Mismatches. The following warning message appears:
