pXe Server
The DataGuard Appliance supports Preboot Execution Environment
(PXE) service to provide a boot environment for remote systems and
diskless nodes. PXE can be used with the embedded iSCSI Boot and
DHCP Servers to provide full-service boot up for iSCSI client systems.
Use the PXE Server Settings menu to enable PXE, define the Share
Folder used to store the boot file and the File Name of the boot file.
Click on the Submit button to commit the settings. The service must
then be started by clicking on the Start button. The default file name is
the standard pxelinux.0, but can be changed to any legal file name for
a boot file.
iSCSi boot Server
The iSCSI boot service, together with DHCP service and PXE, are used
to provide full-service boot up for properly equipped iSCSI clients.
Typically the iSCSI client will be an initiator or diskless client running
iSCSI booting software. To use the iSCSI Boot Server feature, follow
these instructions:
1. Click the Administration tab > Service > iSCSI Boot Server.
2. Click to check the Enable Services option box.
3. Choose the Mode of the server for Single or Multiple client systems.
