from the BMC in this system. Therefore, you can use each RSA II Web interface
in this complex to manage your partitions.

The BMC gets the partition descriptor information of all other nodes in this
complex by exchanging information through the connected scalability cables on
the scalability ports at the rear side of your server. Figure 4-10 on page 211
shows the scalability ports.
Note: The Complex Descriptor is unique; it contains all system and partition
information.
4.3.2 Complex Descriptor contents
The contents of the Complex Descriptor include:
A unique Complex Descriptor signature
Number of chassis
UUID and structure of each chassis
Logical component ID (to specific which one is the primary)
Partition ID (a unique partition identifier)
Node power state
Number of partitions
200
