BL460c G7 - RHEL5 - Bonding of Emulex and Broadcom NICs

Hi,

 

Looking at the specs of the BL460c G7 I see that HP have moved to using Emulex adapters for the onboard NICs.

 

Has anyone had any experience of bonding the onboard NICs with a Broadcom mezzanine card - the NC382m, on Red Hat Enterprise Linux 5 ?

 

I've previously had issues bonding Broadcom and Intel cards, so just trying to preempt any potential issues.

 

Regards,

 

Rob

Re: BL460c G7 - RHEL5 - Bonding of Emulex and Broadcom NICs

Hi, I've got and BL460c G7 with NC382m mezzanine.

I have a lot of issue on RHEL5 (update 6 and update 7 BETA) and Oracle EL 5.6. Mezzanine card driver of NC382m sometime is loaded before be2net driver (embedded card). Sometime eth0 is a Broadcom, sometime is a Emulex, furthermore bonding on NC382m do not work:

 

/etc/modprobe.conf

alias scsi_hostadapter shpchp
alias eth0 bnx2
alias eth1 bnx2
alias eth2 be2net
alias eth3 be2net
alias scsi_hostadapter1 cciss
alias scsi_hostadapter2 qla2xxx
alias scsi_hostadapter3 usb-storage
alias net-pf-10 off
alias ipv6 off
options ipv6 disable=1
alias bond0 bonding
options bond0 mode=1 miimon=100 use_carrier=0
options bonding max_bonds=2
alias bond1 bonding
options bond1 mode=1 miimon=100 use_carrier=0
options bonding max_bonds=2

ip link command output

Re: BL460c G7 - RHEL5 - Bonding of Emulex and Broadcom NICs

Hi to all,

 

I have similar bonding problem, but only with Emulex NIC, Broadcom is working correct:

 

Bonding miimon=100 for Emulex ethernet ports is not working. If I unplugg cable, Link will staid up (MII Status: up)and traffic will be losted. more /etc/sysconfig/hwconf class: NETWORK bus: PCI detached: 0 device: eth0 driver: be2net desc: "Emulex Corporation OneConnect 10Gb NIC (be3)" network.hwaddr: 9c:8e:99:1f:a1:a8 vendorId: 19a2 deviceId: 0710 subVendorId: 103c subDeviceId: 3315 pciType: 1 pcidom: 0 pcibus: 2 pcidev: 0 pcifn: 0 - class: NETWORK bus: PCI detached: 0 device: eth1 driver: be2net desc: "Emulex Corporation OneConnect 10Gb NIC (be3)" network.hwaddr: 9c:8e:99:1f:a1:ac vendorId: 19a2 deviceId: 0710 subVendorId: 103c subDeviceId: 3315 pciType: 1 pcidom: 0 pcibus: 2 pcidev: 0 pcifn: 1 - On another hand, if I configured bonding with arp_interval and arp_ip_target system recognized when cable is unplugged: cat /proc/net/bonding/bond0 shows that ,MII Status: down ifconfig -a show that interface is RUNNING - also BUG But traffic will not be losted and stand by ethenret interface will handle it.
