c. Ethernet interface: If the network adapter used to reach the install server differs from that used to
reach the boot server, and an ethernet adapter is used, select the correct interface to use, either en
(standard ethernet) or et (IEEE 803.1 ethernet).
d. Ethernet connection type: If the network adapter used to reach the install server differs from that
used to reach the boot server, and an ethernet adapter is used, select the correct ethernet connection
type, either BNC (coax) or DIX (15-pin D-shell).
Using the Same Boot Server to Install Different AIX Levels
The same boot server may be used to boot clients of any platform, network type and AIX install level. The boot
server does not need to have any device support installed to support the client’s hardware and does not need to
run the same level of AIX as the client. The SBAdmin System Recovery process uses a unique network boot
process that does not require identical AIX levels on the client and server and does not use NFS mounted /usr
filesystems as do other AIX network boot applications.
Instead, you use a separate option to create a network boot image on any system running the AIX level you will
be installing, and copy that boot image to the boot server. Each boot image is saved under a different name and
may be separately selected when you configure a client to network boot. This 2-step process is described
above in this section. First,
Create a Network Boot Image (which also copies the boot image to the boot server),
then Enable the Network Install of a Client by selecting the boot image on the server you previously created.
Updating Network Boot Images
If you have installed new base system hardware support (network devices, disk drives, platform types or display
adapters) onto a system that you previously created a network boot image from, you will need to recreate that
network boot image before the new device support will be accessible to the clients booting from that image.
After installing the new device support, simply follow the instructions for Create/Update a Network Boot Image
to recreate the boot image and copy to the boot server. If you recreate the boot image for the same platform,
network and AIX level, it will not be necessary to reconfigure the clients for network boot/install since the clients
using the previous boot image will automatically begin using the newly created boot image.
