Oracle^® Server X5-4 Product Notes

FMA Warning Messages About MSI-X Interrupt Vectors (20724005)

During network OS installation, some x86 systems with large configurations that include a lot of network cards might generate FMA warnings about running out of MSI-X interrupt vectors. These messages are harmless and are not seen after the installation finishes and the system reboots to the operating system.

The FMA warnings and description appear as:

fault.io.nic.config
The network device failed to configure a feature. A(n) unsupported error has been detected during
driver's attach context causing a(n) config service impact while involving the device's rx_ring subsystem.

Workaround

To fix this issue, edit the GRUB entry to pass the boot parameter: ddi-msix-alloc-limit=2.

1. During boot, when the Oracle Solaris version information appears on the screen (for example: Oracle Solaris 11.2.9.0.5), type e to edit this entry.
2. Find the following multiboot line:

   $multiboot /ROOT/solaris/@/$kern $kern -B console=ttya -B $zfs_bootfs -B

3. Revise the line by appending the following parameter to the end:

   ddi-msix-alloc-limit=2

   For example:

   $multiboot /ROOT/solaris/@/$kern $kern -B console=ttya -B $zfs_bootfs -B ddi-msix-alloc-limit=2

4. To continue booting with the above revision, press Ctrl + X or F10.
