Unable to Mount Oracle System Assistant USB Device on Some Versions of Linux
After hot-plugging 2 PEMs with different MPS values into the same slot sequentially, the Oracle Linux 6 operating system reports many CE messages. An MPS value can only be auto-negotiated once. Thus, the value negotiated with the first PEM may be different than the value required by the second PEM.
This mismatch may cause a CE (Corrected Error) pop-up. CEs are acceptable messages and do not harm the running system. The operating system may also receive a UE fatal error and stop the system on Sun Blade X4-2B Server Module.
Workaround
Some Linux operating systems have a hotplug patch available for this case. A user may select either of the below kernel parameters for the workaround.
pci=pcie_bus_safe //Set MPS to the minimum size. The PCIe Specification states 128.
pci=pcie_bus_perf //Set MPS to the largest available size. The real value is dependent on the MPS capability of both devices across a PCIe link.
