MAP 3240
Use this MAP to resolve the following problem: Multiple controllers connected in an invalid configuration (SRN nnnn-9073) for a PCIe2 or a PCIe3 controller
The possible causes are:
- Incompatible adapters are connected to each other. Such an incompatibility
includes invalid adapter combinations such as the following situations.
See PCIe2 SAS RAID card
comparison and PCIe3
SAS RAID card comparison for a list of the supported adapters
and their attributes.
- A PCI-X or PCIe controller is connected to a PCIe2 or a PCIe3 controller.
- Adapters have different write cache sizes.
- One adapter is not supported by AIX®.
- An adapter that supports multi-initiator and high availability is connected to another adapter that does not have the same support.
- More than two adapters are connected for multi-initiator and high availability.
- Adapter microcode levels are not up to date or are not at the same level of functionality.
- One adapter, of a connected pair of adapters, is not operating under the AIX operating system. Connected adapters must both be controlled by AIX.
- Adapters connected for multi-initiator and high availability are not cabled correctly. Each type of high availability configuration requires specific cables be used in a supported manner.
Step 3240-1
Determine which of the possible causes applies to the current configuration and take the appropriate actions to correct it. If this does not correct the error, contact your hardware service provider.
When the problem is resolved, see the removal and replacement procedures topic for the system unit on which you are working and do the "Verifying the repair" procedure.
