Important Operating Note

Oracle Server X9-2 does not support Oracle Dual Port SFP28 CX6 LX 25Gb PCIe cards in servers with Oracle Linux 7 Update 9 with the Unbreakable Enterprise Kernel Release 5 (UEK 5) Update 5 operating system installed.

Important Operating Note

On systems running Linux with Intel network interface cards or LAN-on-Motherboard (LOM) controllers, if MMIO memory access is set to strict access in the Linux kernel (iomem=strict or as part of the kernel build configuration) you will see the following message in syslog/dmeg when running the Oracle Hardware Management Pack fwupdate tool:

kernel: Program fwupdate tried to access /dev/mem between
c4a00000->c4a01000. (Address may vary)

This message is expected and should not cause an issue with the operation of the operating system. There will be one message each time fwupdate is run and the kernel is in strict MMIO access mode.

However, when the kernel is running in this mode, fwupdate will not be able to access Intel-based network controllers to either list information or update firmware.

For more information on this issue including a workaround, see the "Linux MMIO Access Settings Can Affect fwupdate Commands On Intel Network Controllers" section in the Oracle Hardware Management Pack 2.4 Server CLI Tools User's Guide at: Oracle Hardware Management Pack 2.4 Documentation.
