Course Summary

                                                                                                             Length: 2 days

Prerequisite: Introduction to AIX 6L System Administration

Recommendation Statement: The student should understand basic UNIX commands such as navigating directories, working with files and using the VI editor. In addition, the student should understand AIX file systems and how to install the AIX operating system from a local CD/DVD in a non-NIM environment.

Course Description: This course is for system administrators and operators that need to understand how to perform Network based installations of AIX 5L and 6L. You’ll learn how to perform NIM tasks such as configuring the NIM Master, NIM resources and NIM clients.

VIO BASICS

VIO
IT IS ALSO ONE LPAR, IT ALLOWS SHARING OF PHYSICAL RESOURCES BETWEEN LPARS(AIX)
MAX FOR M.M ARE 4

MIMIMUM REQUIREMENTS TO CREATE A LPAR

·                     cpu

·                     memory 

·                     i/o devices

PHYSICAL RESOURCES
predefined resources(inbuilt)

SHARED RESOURCES
resources used by several lpars

DEDICATED RESOURCES
entire processor is allocated for single lpar

VIRTUAL RESOURCES
it tells to o.s howmany physical processors it thinks it has.

LOGICAL RESOURCES
logical processor count is based on smt enable/disable

HMC
it is a linux based software to allocate resources between lpars
each hmc can support for 48 manage machines

MANAGE MACHINE
it contains the sources(cpu,memory,i/o)
it is connected to one or two hmcs

POWER HYPERVISER
it is a service proGRAM which is used to allocate resources between lpars

NVRAM
it is a part of manage machine it contains lpar configuration information.power hypervisor use this information to allocate resources.

FSP
manage machine and hmc are connected to it through adapter

SMT
two or more hardware threads run simultaneously on a single processor at a time

Partition profile 
each partition is having atleast one profile.it contains information about resources 

System profile
collection of partition profiles is called s.p

Partition activation

·                     through partition profile

·                     through system profile

Manage machine activation

·                     partition standby

·                     system profile 

·                     partition auto start 

·                     hardware discovery

dlpar
using this we can add/remove/move the resources
DEMONS:
IBM.DSRM
IBM.DRM
CTRMC
LSPARTITION -DLPAR

LUN MAPPING:
WE NEED CREATE ONE VIRTUAL SERVER SCSI ADAPTER IN SERVER SIDE,IT IS CREATED AS VHOSTN
WE NEED CREATE ONE VIRTUAL CLIENT SCSI ADAPTER IN CLIENT SIDE ,IT IS CREATED AS VSCSIN
AFTER THAT WE NEED TO EXECUTE COMMAND CFGMGR
AFTER THAT BY CHECKING DISK AVAILABILITY WE NEED ALLOCATE A DISK FOR CLIENT
MKVDEV =VDEV DEVICENAME -VADAPTER VIRTUAL SERVER SCSI ADAPTER -DEV VTDNAME 

SEA
it acts as a bridge between physical and virtual networks
vio version 1.2 onwards
requires power hyperviser and advanced power virtualization feature

Pvid and vlanid
SINGLE NETWORK IS DIVIDED INTO MULTI NETWORKS LOGICALLY
PVID:IT IS DEFAULT VLANID

ether channel
two or more physical adapters grouped together to act as an logical adapter to provide fault tolerance and to increase high speed links between switches and networks

HEA
JUST LIKE SEA IN VIO  IN P6 MANAGE MACHINE

IVE
JUST LIKE SEA IN VIO IN P5 MANAGE MACHINE

asmi:
 THROUGH ASMI WE CAN CHANGE MANAGE MACHINE NAME
 WE CAN POWER ON AND POWEROFF MANAGE MACHINE
 WE CAN CHANGE LMB SIZE
 WE CAN GET RESOURCES INFORMATION(CPU,MEMORY) 
WE CAN CHANGE THE FIRMWARE LEVEL
we can see errlog info
vpd and fsp info
we can know deconfigured cpu&memory
we can change the m.m ip address
