Details

A fatal error occurred on the interface between an IO Channel (1/2 of an IOC) and a SC chip.
The domain that is using the IO Channel is reset.
The IO Channel will be deconfigured after the domain is reset.

Availability of I/O devices depends on which IO Channel was deconfigured.

SPARC Enterprise M4000 platforms:
IO Channel 0 provides access to PCI-X slot 0, PCI-Express slots 1 and 2,
and all the internal I/O.

IO Channel 1 provides access to PCI-Express slots 3 and 4.

SPARC Enterprise M5000 platforms:
IO Channel 0 provides access to PCI-X slot 0, PCI-Express slots 1 and 2, and all the internal I/O.

IOU#0: Internal I/O includes the DVD drive, the DAT drive, HDD#0 and HDD#1.
IOU#1: Internal I/O includes HDD#2 and HDD#3.

IO Channel 1 provides access to PCI-Express slots 3 and 4.

SPARC Enterprise M8000/M9000 platforms:
IO Channel 0 on IOC chip 0 provides access to PCI-Express slots 0 and 1 on this IOU.
IO Channel 1 on IOC chip 0 provides access to PCI-Express slots 2 and 3 on this IOU.
IO Channel 0 on IOC chip 1 provides access to PCI-Express slots 4 and 5 on this IOU.
IO Channel 1 on IOC chip 1 provides access to PCI-Express slots 6 and 7 on this IOU.

The recommended service action for this event is to schedule the replacement of the affected FRU.

Step 1.  Collect the fault message (use one of the following methods):
