PowerHA HACMP on VIOS servers

Few questions regarding Power HA ( previously known as HACMP) and VIOS POWERVM IVM ( IBM Virtualization I/O Server )

[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

NAME

       scsimgr_fcd - Fibre Channel interface driver fcd plug-in for scsimgr

DESCRIPTION

       The  Fibre  Channel interface driver plug-in for implements management operations specific to fibre channel HBA controllers bound to driver
       is the native HP-UX Fibre Channel interface driver that manages fibre channel devices.

       The plug-in handles the following operations for driver

	  o	 Get, set and save per driver instance attributes.

   Commands
       The user can explicitly send the following commands to the driver plug-in by  specifying  the  instance#>  HBA  controller  hardware  path>
       instance#> option:

	  Displays information on attributes.

	  Saves value of attributes in a persistent store.

	  Sets values of attributes.

       Refer to scsimgr(1M) for the syntax of these commands.

       automatically invokes the plug-in to perform the driver specific part of the operation when the operation applies to per driver instances.

   Attributes
       The following table lists driver specific attributes.  For details on the concept of attributes refer to scsimgr(1M).

       Note: The following conventions are used:

	  o RO is Read Only.

	  o RW is Read Write.

	  o string is an array of characters.

       ---------------------------------------------------------------------
       Object	   Attribute Name  RO/RW  Type	  Description
       ---------------------------------------------------------------------
       Controller  sym_port_name   RW	  string  Symbolic  Port  Name	for
						  fibre  channel  HBA  con-
						  troller
						  Default:	     <host-
						  name>_fcd<instance#>
       ---------------------------------------------------------------------
		   sym_node_name   RW	  string  Symbolic  Node  Name	for
						  fibre  channel  HBA  con-
						  troller
						  Default:   <hostname>_HP-
						  UX_<os release version>
       ---------------------------------------------------------------------

EXAMPLES

       Display all attributes for HBA controller with DSF /dev/fcd1:

       Get HBA controller symbolic port name for DSF /dev/fcd1:

       Get HBA controller symbolic node name for hardware path 0/2/1/0:

       Set HBA controller symbolic port name for DSF /dev/fcd1 to fcd1_port:

       Set HBA controller symbolic node name for class fc and instance 8 to fcd1_node:

       Save HBA controller symbolic port name for DSF /dev/fcd1 as fcd1_port:

       Save HBA controller symbolic node name for hardware path 0/2/1/0 as fcd1_node:
