Issue with DLPAR & RMC

[bomahony]

I have setup a VIO server for the first time on a test p505, and added
various partitions (two AIX). however i cannot use any Dynamic
options. I know this is an issue to do with RMC & the fact the HMC is
on two seperate networks.

Lan & HMC & Servers = 172.16.165.X (subnet 255.255.248.0)
HMC & Service Processors = 10.0.0.X (subnet 255.255.255.0)

I can see the machine, create partitions etc.

I had a look at
http://www.ibm.com/developerworks/systems/articles/DLPARchecklist.html

I have added the machine to /etc/hosts
10.0.0.254 eiffel

Also added to /etc/netsvc.conf
hosts=local,bind

I have restarted the HMC.

I followed the setup guide in the "PowerVM Virtualization on IBM
System p Introduction and Configuration Fourth Edition.pdf" so its
setup pretty much as the VIO diagram on page 183.

When i check the interfaces on the VIO server, i only have en3 and the
lo0 adapters.

Anyone have any ideas?

What is the output of
$ lspartition -dlpar

What OS version and which version of rsct ? - There is problem with a
certain version of the rsct afaik.

First of all it's not ip traffic over the serviceprocessor network
that completes the DLPAR operations.
You need to have working ip communication over the network that is
configured inside AIX/VIOserver LPARS (172.16.165.X (subnet
255.255.248.0) )
If you have a firewall: port TCP 657 and UDP 657 needs to be open
inbetween the HMC and the LPAR

If you got all these prereqs covered and it still doesn't work you
could try to reset and rebuild the RMC connection with the following
commands:
echo "Stopping RMC"
/usr/sbin/rsct/bin/rmcctrl -z
echo "Reconfigures and restarts the RMC subsystem"
/usr/sbin/rsct/install/bin/recfgct
echo "Re-enables remote connection"
/usr/sbin/rsct/bin/rmcctrl -p

It was HMC 7.3.4

I eventually got RMC working (firewall issues, with many things turned
off.)

However, i have run into two other problem (please bear with me as
this is my first time mucking about with VIO / DLpars). Here is my
scenario.

#1:
server1 is AIX. When is ert up the Lpar, i didnt click "Access
External Network", so this prevent RMC working, as there was no
diurect link. The network interface was there at a console login, but
it obviously wasnt working. On the HMC i went to Configuration ->
Manage Profiles -> and edited the adapter to allow external network
access. Obviously as the machine had no RMC connection, i needed to
shut it down and reactivate it. When i reactiivate, ifconfig only
gives the loopback adater. When i run lsdev -Cc adapter, it says ent0
is "Defined", so its not actually available to the partition. The ONLY
other LPars running on the system are the VIO server and this server
(no other DLpars basically). The "Dynamic Logical Partitioning ->
Virtual Adapters" doesnt show it, but the Configuration, Manage
Profiles does.
It is also marked as Required = No"
Is there a way to get the AIX lpar to see it?

#2:
I have my Cd drive set up as a virtual device, and it is coming up as
available. However if i want to release this for another system to
use, how do i do it from within AIX or the HMC web interface? On
another machine how do i take control of the CD drive.

Thanks
