I have the scenario, that there 3 VIOS in a Frame in this 2 are in dual VIOS
My question is how to find which VIOS are in dual?
Also, any vios command to identify the pair member (hostname) of a dual VIOS
Regards,
Siva

I have a p520 box running 3 LPARs, 1 x VIOS, 1 x AIX 6.1 and 1 x AIX 7.1 and no HMC, all configuration is performed via VIOS/IVM
Until recently the box did not have the AIX7.1 LPAR and everything was fine with the box.
We needed to use AIX 7.1 for a new project, so I created a new LPAR and configured it to share the non-VIOS resouces equally with the AIX6.1 LPAR. Everything seemed to go well and I was able to install AIX 7.1 successfully and start using that via PuTTy and FTP as required.
However, it seems that everytime we need to cold-boot the machine, the AIX7.1 LPAR looses visibility of the network. The VIOS and AIX6.1 LPARs remain fine with full network connectivity.
In my investigations so far I have found the following from the VIOS LPAR:
$ lsdev

[1] Is it possible to create HACMP cluster between two VIOS servers
Physical Machine_1
VIOS_SERVER_1
LPAR_1
SHARED_DISK_XX
VIOS_SERVER_2
Physical Machine_2
LPAR_2
SHARED_DISK_XX
In this scenario, You will have to assign the shared disk first to the VIOS server and from there it will be assigned to LPAR.
Would HACMP work on this shared disk ?
[2] Can you have DLPAR ( Dynamic LPAR ) capabilities in IVM , that is assign one physical Fiber Adapter card to LPAR directly ? IVM VIOS ( which is you are running VIOS without HMC = Hardware Management Console )
in this scenario, you can give the LPAR , shared disk directly from the Storage ? ( provided feature is supported ?! )
[3] DO I need HMC for NPIV or can it run on IVM only ?
What is NPIV?
N_Port ID Virtualization(NPIV) is a standardized method for virtualizing a physical fibre channel port. An NPIV-capable fibre channel HBA can have multiple N_Ports, each with a unique identity. NPIV coupled with the Virtual I/O Server (VIOS) adapter sharing capabilities allow a physical fibre channel HBA to be shared across multiple guest operating systems. The PowerVM implementation of NPIV enables POWER logical partitions (LPARs) to have virtual fibre channel HBAs, each with a dedicated world wide port name. Each virtual fibre channel HBA has a unique SAN identity similar to that of a dedicated physical HBA.
The minimum requirement for the 8 Gigabit Dual Port Fibre Channel adapter, feature code 5735, to support NPIV is 110304
