Link timeout to PCIe device with Superdome 2 XFabric failover.QXCR1001233383
This problem was reported on Superdome2 servers, involving PCIe dual-port LAN controller
chips (AD221A, AD222A, and AD393A adapters). An error on the Superdome 2 XFabric
link immediately causes a fabric failover from that link to the redundant path. Transmissions
that were in process on the failing link are replayed along the redundant path. During Crossbar
Fabric failovers, an I/O adapter could encounter a completion timeout (CTO) for transactions
being transmitted at the instant of failover. In such a scenario, the adapter might be declared
as defective although it is performing well. The CTO value on the affected I/O adapters is
not high enough to account for the XFabric failover time.
Table 2 HP-UX 11i v3 December 2012 fixes — IEther-00 B.11.31.1212
DescriptionSR number
On multiple-CPU systems and a high-transmit load, the iether driver might cause intermittent
system hangs or high CPU utilization.

In addition, under these circumstances, systems with MC/Serviceguard might exhibit a
cluster-reformation or system Transfer Of Control (TOC).
Potentially poor network performance might be observed when operating the LAN adapter
at 10Mb or 100Mb half-duplex. The following adapters could be impacted: AD221A,
AD222A, AD393A, and rx2800 LAN on Motherboard (LOM) adapters.
