Netboot process for the N3700 storage system

The netboot process enables you to boot your N3700 storage system from a
remote server if your CompactFlash media becomes damaged or unusable.

Configuration requirements for netboot servers

You can configure a system to serve boot images to IBM devices that support the
netboot process. To do so, you must configure the following items:
v HTTP and/or TFTP services on your system
v The rest of your netbooting environment to use the system as the netboot source
For example, you might configure BOOTP, DHCP, bootparamd, and/or rarpd,
depending on the specific procedure you are using.
Note: For more information about the netbooting process, see the IBM System

Performing the netboot process from a remote image

To perform the netboot process on an N3700 storage system from a remote image,
complete the following steps:
1. Place a Data ONTAP boot image on a local HTTP server. You can copy the
2. At the N3700 storage system CFE prompt, enter one of the following
3. At the CFE prompt, enter the following command:
Note: If you performed the netboot process because your CompactFlash card is

Booting your N3700 storage system from a backup firmware image

This procedure boots your N3700 storage system using a stored backup firmware
image and should only be used as a last resort.

Booting with a backup firmware image

To boot using a backup firmware image, complete the following steps:
