Older model rs6k-platform machines may require IPL ROM emulation to boot over the network. To determine whether or not a running rs6k machine requires emulation, enter the command bootinfo -q AdapterName where AdapterName is the network adapter over which the client will be installed. If the adapter is network-boot enabled, the bootinfo command will return 1, and no emulation is required. For example, enter:
bootinfo -q tok0
If an rs6k machine is not running, it is possible to determine whether IPL ROM emulation is required by booting the machine with the key turned to Secure. If the LEDs on the front of the machine eventually stop at 200, no emulation is needed.
Note: On model numbers 570, 580, 58H, 59H, 591, and 595, the system powers on in the Secure mode, the power-on light does not come on, and the LED remains blank. Refer to the documentation that came with your particular hardware model for more information.
To create IPL ROM emulation, see "Creating IPL ROM Emulation Media".
The platform and kernel type of a client determines the procedure required to boot the machine over the network.
To determine the platform of a running machine, use the bootinfo -p command if the machine is running AIX Version 4.2 or later. If the machine is running AIX Version 4.1, use the bootinfo -T command.
To determine the kernel type of a running machine, use the bootinfo -z command.
