Performing Node Reconfiguration 157
Recovering from a Failed CMP/Memory
Module
If your system experiences a complete CMP/memory module failure, do one of the
following:
1. Replace the failed CMP/memory module.
2. If a replacement CMP module is not available, remove the failed CMP module and
replace it with a CMP from a different slot that does not have any directly
connected I/O devices in use (see
TABLE: Devices controlled by CMPs in 2P
systems on page 164 and TABLE: Devices controlled by CMPs in 4P systems on
page 165 ). If this leaves a memory module without its associated CMP module,
remove the memory module.
Note – At a minimum, a functioning CMP module must be installed in CMP Slot 0.
If you are performing a node reconfiguration following a failure in CMP Slot 0, you
must move one of the remaining CMP modules to CMP Slot 0.
3. If neither option (1) nor (2) is possible, you must do the following:
■ “Temporarily Disable All Memory Modules” on page 160
■ “Reconfigure the I/O and PCIe Fabric” on page 158
■ “Re-Enable All Memory Modules” on page 161
■ “Reset the LDoms Guest Configuration” on page 162
