AIX - LPAR / DLPAR

AIX - LPAR / DLPAR

We can configure LPAR and DLPAR in P690 Servers,

LPAR (Logical partitions)

In single server we can install multiple operating systems, like AIX 5.1, AIX 5.2, AIX 5.3, Susi Linux, AIX 4.3, and using LPAR concept

The above Os are installing in single server, before that we have to partition the hardware resources, like processors and memory, Harddisk,

Using HMC (Hardware Management Console) we can partition and operate the LPAR servers

If you have one P690 server with 16 CPU’s and 16GB Ram, in this server we can make 16 partitions,

Now each partitions has 1 CPU and 1GB Ram,

If one particular Os assigned for 500 users that time we have to assign additional hardware resources to that partition, online we can assign the hardware resources using HMC. No need to reboot the server, this concept called DLPAR (dynamic Logical Partition)

Like this we can create the LPAR / DLPAR

HMC - it is a desktop pc (Linux OS) connected with P690 server through Communication (com port) cable or RJ45 Ethernet cat cable

Using HMC we can Create, Delete, and Change the Logical Partitions

This LPAR server has hypervisor Controller, all the information’s stored in this hypervisor, and it is used to maintain the server

Accessing methods:

1. wsm (Web based system management , using this concept we can access the LPAR servers from windows desktops)
2. ssh (Secured shell, using this concept we can access the LPAR servers through telnet)
