v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved. If an action solves the problem, then you can stop performing the remaining actions.
v See Chapter 3, "Parts listing, type 7891," on page 225 to determine which components are CRUs and which
components are FRUs.

Description
PCI-E switch had an unrecoverable
failure. All downstream I/O is failed.
PCI-E switch has detected a firmware
action that was not valid. All
downstream I/O is failed.
PCI-E switch had a correctable error.
Downstream I/O is not affected.
PCI-E switch downstream I/O bus had
a recoverable failure. The downstream
IOA might be failed.
PCI-E switch downstream bus had
recoverable failure, but has reached the
threshold of recovery attempts. The
downstream IOA is failed.
Action
1. Collect error logs and info logs.
2. Collect the configuration data for the IOAs
downstream of the PCI-E switch.
3. Replace the system-board and chassis
assembly, as described in "Replacing the
FRU system-board and chassis assembly"
on page 264. Send the failed FRU and the
data to IBM for fault analysis.
1. Collect error logs and info logs.
2. Collect the configuration data for the IOAs
downstream of the PCI-E switch.
3. Update the firmware to the current level, as
described in "Updating the firmware" on
page 267.
4. If the problem persists, replace the
system-board and chassis assembly, as
described in "Replacing the FRU
system-board and chassis assembly" on
page 264. Send the failed FRU and the data
to IBM for fault analysis.
No corrective action is required.
Look for and resolve other errors. If there were
no other errors, then the PCI-E switch recovery
was successful. In either case, determine if any
downstream I/O adapters are in failed states
and to which partitions they belong. The
partition or application associated with the
failed downstream I/O might have to be
restarted.
1. Collect error logs and info logs.
2. Collect the configuration data for the IOAs
downstream of the PCI-E switch.
3. Replace the system-board and chassis
assembly, as described in "Replacing the
FRU system-board and chassis assembly"
on page 264. Send the failed FRU and the
data to IBM for fault analysis.
4. After the FRU has been replaced, the
partition or application associated with the
failed downstream I/O might have to be
restarted.
