We have purchased IBM Pureflex chassis with 5 P460 blades. We have configured each blade with dual vios and 4 vio clients. VIOS installation and vio client installation and configuration was completed successfully.
When we tried to connect the network cables from Pureflex internal I/O module to core switch(access switch) other existing lpars(live servers) in our existing environment(P700) are unreachable.
we have chosen different IP(192.168.7.xxx) of vlan 100 for new servers in IBM Pureflex, however the existing server have IP range 192.168.0.xxx) of vlan 100.
Your network setup is faulty from the beginning: a "VLAN" is a virtual construct which matches a collision domain, therefore to interact with another network you need to couple these with either a bridge or something operating on a layer higher than 2 (like a router, ...).
If you configure your VLAN 100 to be the basis of network 192.168.0, which is a Class-C-network (=8 bit host mask) it can't be the basis of the network 192.168.7 at the same time, because this is another Class-C network.
We have pureflex here.. first, you have to add the needed vlans to the trunk adapters on each vios, then create the vlans and map them to internal p460 nodeso n the ethernet swicthes, later you need to tell network team to setup the same vlans on their side.. it's complicated but not impossible..
