Scott,

 

Here the information from my z/Linux ADMIN. Note that the IP's are
masked  as we cannot send or publicize them Security reasons. Let me
know what you think.

Terry - we need to see the ifcfg-eth1 file - and maybe ifcfg-eth0 too to
help...   I think you'll find them under /etc/sysconfig/network-scripts/
(?)     You're showing us the config for what works - but not the config
for what doesn't...

Hi 

 

I have a dilemma that I hope you can help with:

 

I have cloned a z/VM LPAR and a z/Linux guest from my Production system.
I have a VSWITCH set up and a matching NIC def in the Directory for the
z/Linux guest.

 

I can display the OSA and see that it is attached to the VSWITCH and I
can see that the NIC was configured correctly when the z/Linux guest is
logged on.

 

The z/Linux guest is RHEL 5.2. The problem is when the guest initializes
we see this message:

 

Bringing up interface eth1:  qeth device eth1 does not seem to be
present, delaying initialization.   

 

When I display the VSWITCH  Q VSWITCH DET I expected to see the IP
address associated with the network interface show up in the VSWITCH
which tells me the we can get to the z/Linux guest but I don't see the
IP.

 

Now if we bring the z/Linux guest up in RESCUE mode where it is reading
the CONF file where I specifically enter the  IP address I can display
the VSWITCH and see the IP address associated with the VSWITCH as I
expected and we can PING the z/Linux guest and login to it.

 

So what am I doing wrong here? Why on a normal boot can't I see the IP
in the VSWITCH and hence login into the z/Linux guest or PING it but
when I load it using the CONF file in RESCUE mode I can login to the
guest and PING it what am I missing?:
