After replacement of the Cluster Con-

new Cluster Controller logs into Sunny Portal with a new
system identifier. Sunny Portal creates a new system for
this system identifier, even if you have given the system the
same name.
Corrective measures:
• Assign the system identifier of the old system to the
replacement device (see Section 11.6, page 63).
