Setting up the network interface as a startup device
This section describes how to enable the F12 function key to set up the network interface as a startup device.
On some HMC models,
the F12 function key is not enabled for use when the HMC is powered on. These
steps enable the F12 function key so that you can specify the network
interface as a startup device.
To set up the network interface as a startup device, you
must be a member of one of the following roles:
- Super administrator
- Operator
- Service representative
To set up the network interface as a startup device, do the following:
You can now press F12 to select the network device as the
startup device. If a DHCP server can accept PXE requests from the
HMC, and has the required files, the HMC will boot from it. The Backup/Upgrade/Restore/Install
window opens.
The chhmc command can be used on some HMC machine types to set the network interface as a startup device. To enable network boot on the HMC, use the following command:
chhmc -c netboot -s enable
When the command completes, run the following command to verify that network boot has been enabled:
lshmc -r
The command then displays the following:
ssh=enable,xntp=disable,websm=enable,http=enable,netboot=enable
To disable network boot, use the chhmc command:
chhmc -c netboot -s disable
