Purpose

The PCIe hot-plug carriers from T5/M5/M6 systems have not been qualified for use in the T7 or M7 systems.   
If T5/M5/M6 carriers are used in T7-4 or M7 systems, PCIE I/O failures may occur for the add-in card.

As described in the Service Manual, M7 series and T7-4 servers support the use of only PCIe x16 hot-plug card carriers, which are physically labeled with "x16 CAR" on the faceplate. PCIe x8 card carriers from earlier generations of Oracle servers, which are labeled with "CAR" on the faceplate, are not supported for use in M7 series and T7-4 servers.

The list of supported carriers can be found from the Oracle System Handbook at https://mosemp.us.oracle.com/handbook_internal/index.html.

Fix available in 9.5.2.g

Troubleshooting Steps

Users should only use qualified T7/M7 PCIe hot-plug carriers.

During power on of the physical domain, unsupported carriers will be detected and FMA will generate an ereport so a fault will be diagnosed for the unsupported configuration. The possible ereports, fault and MSGID are :

• ereport.component.invalid-asserted
• ereport.component.invalid-deasserted
• fault.component.misconfigured
• SPT-8000-PX

As a result, the card may be disabled; preventing the card from being used from the host.

If the unsupported carrier is hot-plugged, no detection will occur but the add-in card may or may not work correctly.  Normal Solaris I/O fault handling will retire the add-in card if PCIE errors are seen.

New support is being added to have ILOM check for unsupported carriers added by PCIE hot-plug so ereport and fault will be generated when unsupported configuration is detected.
