DLPAR capable with IVM – checks to do

Leave a comment

By MichaelFelt

I cannot find the post with the comment that DLPAR capability was not working with IVM.

The two commands that need to be run are (as root, padmin does not know this command):
VIOS:
lsrsrc IBM.MngNode
CLIENTS:
lsrsrc IBM.MCP

Examples:

Code:
# lsrsrc IBM.MngNode
Resource Persistent Attributes for IBM.MngNode
resource 1:
Name = "192.168.129.102"
NodeID = 14773711625430560719
KeyToken = "192.168.129.102"
Aliases = {}
IPAddresses = {"192.168.129.102"}
HWType = "020123A4B"
HWModel = "9110-51A"
HWSerialNum = "0123A4B"
LParID = "2"
StorageFacilityImageID = ""
ActivePeerDomain = ""
NodeNameList = {"x101"}
resource 2:
Name = "192.168.129.107"
NodeID = 14592256202647740844
KeyToken = "192.168.129.107"
Aliases = {}

PowerHA HACMP on VIOS servers

Leave a comment

By filosophizer

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
