If you exchanged a server blade that was assigned to a farm and you want the newly placed server blade to be assigned to that farm, you need to add the new blade to the farm.
Delete the replaceFailedDevice request in the database queue.
Replace the failed server blade with a new one.
Get the media access control (MAC) address for the new blade and update the CPDB by typing:
device -s device-ID -o port-name mac-address
Type replacedevice -i
Logon to the Control Center and submit a request for an update using the Control Center Editor.
See the N1 Provisioning Server 3.1, Blades Edition, Control Center Management Guide for details.
