Explanation
PCI-E Switch recovery failure. All downstream I/O is failed.
Response
Exhaustive attempts to recover the PCI-E Switch failed.
If there are AIX/LINUX errors logged against I/O Adapters on this switch, do not replace any I/O Adapter hardware. This SRC is the root cause.
Work with your service provider to collect error logs. Then work with the FRU list in the Serviceable Event View if there is one; otherwise, use the FRU list documented here to determine the parts to exchange. After the FRU has been replaced, the partition/application associated with the failed downstream I/O may have to be restarted.
