STEPS TO CONFIGURE CLUSTER

Ø  Define a cluster

Ø  Configure hacmp nodes

Ø  Configure hacmp networks

Ø  Configure hacmp communication interfaces

Ø  Give persistent ip address

Ø  Add on application

Ø  Add a serviceip address

Ø  Create an RG

Ø  Add RG attributes

Ø  Sync the cluster info of node1 to node2

Ø  Start cluster services

CLUSTER MAIN POINTS

TYPES OF CLUSTERS

Active-passive

Active-active

Concurrent multiactive

SERVICE IP

It acts as a alias ip

BOOT IP

Original ip on the interface

PERSISTENT IP

Used for administration purpose

RG POLICIES

Startup

Fail over

Fall back

IP ADDRESS TAKEOVER

Ipat via aliasing

Ipat via replacement

ctrmc

Dms:

    It is kernel extension which alts the node when enter into the hung state,that extends beyond a certain time limit. It enables the another node in the cluster to acquire the hung node resource in a orderly fashion

Reasons:

·                     Clstrmgr may be starved of cpu

·                     Excessive i/o traffic on a disk

·                     Excessive tcpip traffic over on a interface

Dare:

    Using this we can change the cluster configuration dynamically

Can:

·                     We can add/remove node

·                     We can add/remove interface

·                     We can add/removbe network

Can’t

·                     Changing the cluster name

·                     Changing cluster nodename

·                     Changing rg name

·                     Changing apps server name

DIFFERENCES BETWEEN AIX 5.3 AND 6.1

5.3                                                                              6.1

1.             Default filesysytem type is jfs                               1. Default filesystem type is jfs2

2.             It doesnot contain /admin filesystem                   2. It contains /admin filesystem

3.             Default kernal is 32bit                                             3.default kernal is 64bit

4.             It doesnot support for lpm                                    4.it supports fopr lpm feature

5.             It contains ML mechanisem                                  5. It doesn't contain ML mechanisem

6.             Recent TL is 12                                                       6. Recent TL is 9

7.             We need install nmon feature                              7. Nmon is a default feature init
