IPMI on localhost

[Brent_Clements at Dell.com]

Kilian,
 
Set up two seperate vlans and do vlan routing between the two subnets. You will have to switch from a flat network to a subnetted network before you do so. The 6248's support vlan tagging and vlan routing.
 
If you call Dell networking Support, they can explain how to set this up.

Hi all,

I have a couple PE1950 for which I configured BMCs for IPMI access.
Everything works perfectly when I try to access hostA's BMC from hostB.
But I cannot access hostA's BMC from hostA itself.

hostA's network setup is the following:
  - BMC use the primary network interface connector
  - BMC IP is 10.5.0.1/255.0.0.0
  - OS eth0 IP is 10.0.0.1/255.0.0.0

From, hostB, I can ping 10.5.0.1 and 10.0.0.1 without any problem, and I
can use:
ipmitool -I lanplus -U user -P passwrod -H 10.5.0.1 chassis power status
to get power status information. But from hostA itself, I cannot ping
10.5.0.1 (its own BMC's IP). I even can't get the BMC MAC address, neither
arping'ing it, so it's probably not a netmask issue.

It's quite understandable, since from the OS standpoint, 10.5.0.1 doesn't
exists. But I was wondering if there was a way to circumvent this problem.
I guess it's related to the fact that the BMC and the OS share the same
physical interface, so the packet would have to go out the OS interface
and back in the BMC, which is the same, but I don't really know where to
go from that point.

If anyone have an idea, it would help lot.
