Hi Gregoire,
First of all – I think you’re probably on very thin ice with this one – you may
be able to do this in the lab but it would be very risky to carry out in a
production environment.
Saying that – if you want to persevere and are happy this may break your lab -
a starting point would possibly be:
- Add the new cards to your XenServers.
- Create new networks in XenCentre – with new network labels.
- Not sure if this is required – but you would probably add the new physical
network using CloudMonkey. Keep in mind the physical network is mainly cosmetic
– your network configuration uses labelling only hence you may just use the
existing physical network.
- Stop CloudStack management.
- Hack the network labels in the cloud.host_details and
cloud.physical_network_traffic_types to reflect the new networks.
- On your XenServers / Xencentre move all existing networks (VLANs) to the new
networks (unsure of the steps or if this is possible).
- <insert other magic here>
- Restart management.
One other point – you mention this is for a *primary storage* migration – keep
in mind the storage network in the CS configuration is for *secondary storage*.
If all you want to do is to migrate to a new storage network and a new storage
backend your best bet is to:
- Add the new cards + configure the new storage network on the XenServers – no
need to label this.
- Present new primary storage pools from your NAS on the respective networks –
making sure the new NFS shares are only available over your 10Gbe network.
- Add the new NFS shares as new primary storage pools in the ACS gui.
- Storage migrate from old NFS shares to new.
This is a much simpler way and would be a supported configuration change.
Hope this helps,

Dear All,
In my lab, I have a CS 4.7 advanced zone working fine.
I am now in the process of testing a primary storage migration (currently
SAS based to 10 Gbe nfs).
To perform this migration, I need to attach new network controlers (10 Gbe
controlers)
I have no problem for the hardware part of my work, but I am wondering how
CS can handle this change.
Right now, on my zone conf, I have :
- Physical Network 1
o Management traffic (with XenServer Label)
- Physical Network 2
o Public traffic
o Guest
o Storage
What is the best « CS way » to add my card (each with 2 10 Gbits ports),
add move management + Storage on the first port of the new card ?
- Physical Network 1
o No more traffic
- Physical Network 2
o Public
o Guest
- Physical Network 3 (first port of the new 10 Gbe card)
o Management
o Storage
I tried to play arround with create physical network, but I can't do much
with the newly created network (no way to assign traffic type to them).
Any help would be highly appreciated.
Best Regards.
