Creating a system WPAR

You can create a new system WPAR with the mkwpar command.

Each WPAR has an isolated network environment with unique IP addresses and a unique hostname. You can access WPARs through standard networking programs, such as telnet, ftp, and rlogin (depending on the services running in the WPAR). Before you create a WPAR, you should log in as the root user and complete one of the following prerequisites:

Choose a name for the WPAR that maps to an IP address for your network.
Add an entry for the new system WPAR to the /etc/hosts file on the server. The entry should include the host name for the WPAR and the name of the WPAR as follows:
```
9.3.18.10	WPARname.austin.ibm.com WPARname
```

To create a new system WPAR, complete the following steps.

Verify that the network recognizes your workload partition address by entering the following command:
```
#host WPARname 
```
The return should look similar to the following:
```
WPARname.austin.ibm.com is 9.3.18.10,  Aliases:  WPARname 
```
Configure the WPAR by running the following command:
```
   mkwpar -n WPARname 
```

The initial output of the mkwpar command should look similar to the following:

mkwpar -n WPARname mkwpar:

Each system WPAR has an isolated section of the system's file space configured for the root directory, the /home directory, the /usr directory and other file systems. Creation and configuration of this space is reflected in the above output from the mkwpar command. The return from the mkwpar command continues with output similar to the following:

x ./home 
x ./home/guest 
x ./home/lost+found

Each system workload partition has its own /dev directory. Creation and configuration of this space is reflected in the populate: Exporting workload partition devices output from the mkwpar command. Not all of the devices on the system can be shared among the WPARs so the WPARs /dev directory is a sparse version of the /dev directory on the global environment. The mkwpar command then continues with the installation of several AIX® base system file sets into the WPAR. At the end of the installation phase, you should see output similar to the following:

Finished processing all filesets. (Total time:  1 mins 4 secs).
