Pinned topic RedHat 5.7 on a Power System P710 - eth0 missing

‏2012-02-09T13:21:43Z |
 I've just installed RedHat 5.7  on a Power 710 , I configured the Linux lpar with one HEA/IVE port but I cannot find the related eth0 device even if the hardware is correctly recognized.
The lscfg command showing the following :
+ lhea             U78AB.001.WZSG1PF-P1  lhea                                  
+ ethernet         U78AB.001.WZSG1PF-P1-C2-T1                                  
                                         PORT - 1 IBM Host Ethernet Adapter 
 
also kuzu -p shows:
class: NETWORK                                                                 
bus: VIO                                                                       
detached: 0                                                                    
device: eth0                                                                   
driver: ehea                                                                   
desc: "PORT - 1 IBM Host Ethernet Adapter"                                     
-                                              
but still not able to get the eth0 device.
Even in the dmesg there is nothing related the the ethernet device.
Any ideas on how to fix the problem ?

    Were the interfaces added/removed/adjusted after the initial install? 

    Are there any "ehea" related messages in dmesg?  if not, a "modprobe ehea" may be all that you need.
    (if that is the root issue,.. I would have expected the network configuration steps to have handled this OK.  a re-run with your favorite system-config-network-{gui,tui,cmd} may be appropriate.
     
    Contents of /etc/sysconfig/network-scripts/ifcfg-eth*  and /etc/modprobe.conf may be interesting.
