IPMI not fucntioning with Network Bonding

Hey,

I am having problems with running IPMI on my servers that have network bonding enabled.

Platform: CentOS release 5.3 (Final)

Kernel: 2.6.18-92.el5 

64bit Dell PowerEdge 1950 
Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet 



I  have bonded the interface eth0 and eth1 as active passive, with eth0 as the active interface, below is conf description from /proc

 Bonding Mode: fault-tolerance

(active-backup) Primary Slave: eth0 
Currently Active Slave: eth0 MII 
Status: up MII Polling Interval (ms): 
30 Up Delay (ms): 0 Down Delay (ms): 0 
Slave Interface: eth0 MII Status: up 
Link Failure Count: 0 Permanent HW 
addr: 00:22:19:56:b9:cd 
 
Slave Interface: eth1 MII Status: up 
Link Failure Count: 0 Permanent HW 
addr: 00:22:19:56:b9:cf 



My IPMI device is as follows 

IPMI Device Information 

Interface Type: KCS (Keyboard Control Style) 
Specification Version: 2.0 
I2C Slave Address: 0x10 
NV Storage Device: Not Present 
Base Address: 0x0000000000000CA8 (I/O) 
Register Spacing: 32-bit Boundaries 

 

I Have used openIPMI as well as freeipmi both to control the chassis via the IPMI card, but on servers which have bonding enabled, the command times out, below is the full run of the command with debug info.

ipmi_lan_send_cmd:opened=[0], 
open=[4482848] IPMI LAN host 
70.87.28.115 port 623 Sending IPMI/RMCP presence ping packet 
ipmi_lan_send_cmd:opened=[1], 
open=[4482848]   No response from 
remote controller Get Auth 
Capabilities command failed 
ipmi_lan_send_cmd:opened=[1], 
open=[4482848]   No response from 
remote controller Get Auth 
Capabilities command failed Error: 
Unable to establish LAN session Failed 
to open LAN interface Unable to get 
Chassis Power Status  

On the other hand I configured IPMI on a box with the same specs as mentioned above without bonding and IPMI works perfectly.

Has anyone faced this problem with IPMI + Bonding ?
I would be thankful is someone helps circumvent this issue.

Re: IPMI not fucntioning with Network Bonding

Hi Sameer,

I suspect that you're using the ipmi channel on Gb1(eth0) or LOM. And at the same Gb1/eth0 is part of your bonded interface. Right?

I have faced same issue with my PE1950 server. The only possible solution is to have an DRAC5 controller installed on the system to have OOB(out of band) IPMI management.

Regards,

Gilbert
