3.1.3 Basic partition operations
Partitioning your system is similar to partitioning a hard drive. When you partition a hard drive, you divide a single physical hard drive so that the operating system recognizes it as a number of separate logical hard drives.
You have the option of dividing the system's resources (memory, processor, or adapters) by using the HMC to partition your system. On each of these partitions, you can install an operating system and use each partition as you would a separate physical system. With the introduction of Virtual I/O Server, it is possible to further partition I/O adapters.
Before you begin to create partitions, complete the following activities:
| Record the required subnet mask, any gateway information, and address of your DNS server. |
|
| Check that you have a suitable LAN (hub or switch and cables) to connect to each HMC and each network adapter used by partitions. |
|
| Record the TCP/IP names and addresses to be resolved by a DNS server, or to be entered into the /etc/hosts file in each partition, and on the HMC. |
Determine the following information:
| 
|
| Your current resources for each partition |
|
|
|
| The operating system host name for each partition |
|
|
|
| The partition you want to use for service actions |
|
|
|
| The operating system to be loaded on the partition |
