Performing Node Reconfiguration
If a CMP/memory module pair develops a fault, the SPARC Enterprise T5440 can be
reconfigured to run in a degraded state until the CMP/memory module is replaced.
In addition, you can add CMP/memory module pairs to existing systems. However,
adding or removing CMP/memory modules might affect internal hardware device
addresses, as well as the device address of any external devices attached to the
system such as external disk arrays and devices attached via an External I/O
Expansion Unit.
Depending on which CMP/memory module is added or removed, it might be
necessary to manually reassign one or more I/O devices before they can function
correctly in the new system configuration.
