NIC Bonding Issue on BL460c G7 with Linux
Hello,
I am new to HP servers but now have a new chassis with several BL460c's and the virtual connect modules.
The issue is that the VC modules auto set the port speed, in this case 6000Mb/s, but the linux bonding driver loads with an error and sets the bond0 interface to 100Mb/s full duplex. The error is the following:
bonding: bond0: Warning: failed to get speed and duplex from eth1, assumed to be 100Mb/sec and Full.
I assume the bonding module does not like the non-standard port speeds because if I set the port speed to 100, 1000, or 10000Mb/s the error does not show and the bond0 interface has the correct speed.
I am using the bonding module built in to Red hat 5.7. Is there an HP modified module that should be used? If not is there a way to get the bond0 interface to have the correct speed?

There is an issue with the bonding driver not understanding the "custom" speeds. Please open a case with HP support, and have the case escalated.

I'm sure RHEL will understand those speeds.
I vaguely remember RHEL being ok with 2.5Gb/s as well so if you have the time to test, try that as well.

Re: NIC Bonding Issue on BL460c G7 with Linux
Current versions of RHEL don't have an issue with any custom speeds you can set on a FLEX-NIC in VC. The bonding driver is coded to only recognise specific speeds. The speeds being 10, 100, 1000, 10000
