You might need to change the connection between the CMP modules and the
onboard devices described in
“I/O Fabric in 2P Configuration” on page 168 or “I/O
Fabric in 4P Configuration” on page 169 in one of the following circumstances:
■ A CMP module has completely failed, you need access to a PCIe slot or device
which was attached to that CMP module, and you are unable to temporarily
replace the failed module or move an existing module over from a different slot
until the failed CMP is replaced.
■ You are upgrading from a 2P to a 4P system.
