Example 21-3 shows output from the revert process. First, all 64-bit aggregates were
removed, all snapshots were deleted for all volumes and aggregates (the command in
Example 21-3) and snapshot schedules were disabled. SnapMirror also had to be disabled.
Then the software upgrade command was issued. Finally, the revert_to command was
issued. The system rebooted to the firmware level prompt. You are now able to perform a
netboot or use the autoboot command.

You can use the netboot option for a fresh installation of the storage system. This installation
boots from a Data ONTAP version stored on a remote HTTP or Trivial File Transfer Protocol
(TFTP) server.
Prerequisites: This procedure assumes that the hardware is functional, and includes a
1 GB CompactFlash card, an RLM card, and a network interface card.
Perform the following steps for a netboot installation:
1. Upgrade BIOS if necessary:
ifconfig e0c -addr=10.10.123.??? -mask=255.255.255.0 -gw=10.10.123.1
ping 10.10.123.45
flash tftp://10.10.123.45/folder.(system_type).flash
2. Enter one of the following commands at the boot environment prompt:
– If you are configuring DHCP, enter:
ifconfig e0a -auto
– If you are configuring manual connections, enter:
ifconfig e0a -addr=filer_addr -mask=netmask -gw=gateway -dns=dns_addr
-domain=dns_domain
where:
filer_addr is the IP address of the storage system.
netmask is the network mask of the storage system.
gateway is the gateway for the storage system.
dns_addr is the IP address of a name server on your network.
