Use this MAP to resolve the following problem: Multiple
controllers connected in an invalid configuration (SRN nnnn -
9073) for a PCI-X or PCIe controller.
The possible
causes follow:
- Incompatible adapters are connected to each other. Such an incompatibility
includes invalid adapter combinations such as the following situations.
See the feature comparison tables for PCIe and PCI-X cards for
a list of the supported adapters and their attributes.
- An adapter is CCIN 572A but has a part number of either 44V4266
or 44V4404 (feature code 5900), which does not support multi-initiator
and high availability
- Adapters with different write cache sizes
- One adapter is not supported by AIX®
- An adapter that does not support auxiliary cache is connected
to an auxiliary cache adapter
- An adapter that supports multi-initiator and high availability
is connected to another adapter which does not have the same support
- Adapters connected for multi-initiator and high availability are
not both operating in the same Dual Initiator Configuration,
for example both are not set to Default or both are not set
to JBOD HA Single Path.
- Greater than 2 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. Additionally, both adapters must be in the
same system partition if one adapter is an auxiliary cache adapter.
- 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 3140-1
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.
