Exadata 10GbE Issue Resolved

By | November 14, 2011

It appears that Oracle has resolved the issue with the 10GbE drivers that were introduced in version  There is an updated note (1376664.1) that includes the patch to fix it. The issue was apparently related to TCP segmentation offloading, and can be fixed by installing the patch found in the note listed above. It does not require a reboot, and is similar to the fix for the IDT switch bug fixed in Note that this bug only affected X2-2 systems utilizing 10 gigabit ethernet on the compute nodes. Oracle again recommends installing the minimal pack on compute nodes.

After starting the service, users should see the following:

(root)# service disable10gigtso_13083530 start
Skipping igb interface eth0 using driver version 2.1.0-k2-1 - TSO disable unnecessary
Found ixgbe interface eth4 using driver version 2.0.84-k2 - Disabling TSO ... [SUCCESS]
