Hi...

The even/odd starting address may cause you some problems depending
on the combination of CP HiperSockets and device driver support.  It is
safer
to stick with an even-numbered starting address when you define the NIC.
With the latest CP and the latest device drivers this should work either
way,
but why tempt fate?

Cornelia is correct in pointing out that the portname does not matter here.
HiperSockets does not require a portname, and if your configured portname
does not match that of other interfaces using the same network, that is OK.
If you were using dedicated OSA-Express devices with this interface, you
would have to specify the portname and it would have to match the portname
configured by the other users of that OSA port.  Most users of Guest LAN
are not affected by this because each DEFINE NIC creates an "adapter"
in your virtual machine, so portnames only have to match within the devices
that are part of that adapter range.  Most users create the default adapter
(three devices) and there is no risk of portname conflict.  If you defined
a
TYPE QDIO NIC with six or more devices, all interfaces using that NIC
would have to agree on a portname.  That is NOT a problem on z/VM 4.2.0
because the OSA-Express simulation is not available at that level.

You were concerned about the partial results in Q NIC DETAILS:

> Q NIC DETAILS
> Adapter 0960  Type: HIPER   Name: UNASSIGNED  Devices: 3
>   Port 0 MAC: 00-04-AC-00-00-0E  LAN: SYSTEM LNXLAN02   MFS: 16384

That just means the driver started by initializing 0x960 as the
Control-Read device, and
encountered the IDX failure that you reported.  We were still in "Startup"
state and no attempt
was made to initialize 0x961 or 0x962 so they are still reported as
"Unassigned" devices.

I believe your CP system has been installed with only the z/VM 4.2.0 base
tapes, and
no service.  After the suggested APARs (VM62958 or VM62938) are applied
your current
configuration should work properly.
