B7006A25 • B7006A30
B7006A25
Explanation: PCI-E switch has detected a firmware action that was not valid. All downstream I/O is failed.
Response:
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.
4. If the problem persists, replace the system-board and chassis assembly, as described in Replacing the
system-board and chassis assembly. Send the failed FRU and the data to IBM for fault analysis.
B7006A28
Explanation: PCI-E switch had a correctable error. Downstream I/O is not affected.
Response: No corrective action is required.
B7006A2A
Explanation: PCI-E switch downstream I/O bus had a recoverable failure. The downstream IOA might be failed.
Response: 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.
B7006A2B
Explanation: PCI-E switch downstream bus had recoverable failure, but has reached the threshold of recovery
attempts. The downstream IOA is failed.
Response:
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 system-board and chassis assembly.
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 may
have to be restarted.
B7006A30
Explanation: A PCI-E bus internal connection initialized to a lower bus configuration than expected. The bus is
operational, but operating at a bandwidth below its rated capacity. This might lead to degraded I/O throughput.
Response: If this event appears in a serviceable event view, replace the system-board and chassis assembly, as
described in Replacing the system-board and chassis assembly. If this event does not appear in a serviceable event
view, no service action is required.
