Chapter 7. Installing AIX on the <strong>JS20</strong><br />
7<br />
This chapter discusses NIM. It explains how to configure NIM to install AIX and<br />
how to install AIX on an <strong>IBM</strong> Eserver <strong>BladeCenter</strong> <strong>JS20</strong> using NIM.<br />
<strong>BladeCenter</strong> <strong>JS20</strong> supports the installation of AIX 5.2f and later. We recommend<br />
that you install AIX using a network installation via NIM. NIM is a unified console<br />
that allows the management of several AIX logical partitions (LPARs) or<br />
machines. You may install AIX on new machines or manage existing ones from a<br />
unified interface.<br />
Tip: Prior to installing any operating system, we recommend that you upgrade<br />
all firmware to the latest level. See 5.4, “Firmware” on page 79, for instructions<br />
about how to complete this task.<br />
To use NIM, there should be an available AIX instance with NIM configured on<br />
the same network segment as the <strong>BladeCenter</strong>. In the interest of speed and<br />
security, a private dedicated subnet is recommended.<br />
Our NIM master was configured on a pSeries 690 connected to the same local<br />
area network (LAN) as the <strong>BladeCenter</strong>. This p690 was running the same level of<br />
AIX that we installed on the <strong>BladeCenter</strong> <strong>JS20</strong>.<br />
Note: An installation of AIX may be several gigabytes in size. We recommend<br />
that you use a 100 Mb or faster network for NIM-based installations.<br />
