Booting the FAS200 and FAS3000 series storage systems
Boot options
The FAS200 series (FAS250, FAS270, and FAS270c) and FAS3000 storage systems automatically boot Data ONTAP from a PC CompactFlash card. They do not boot from a set of diskettes or from disk. The CompactFlash card ships with the most current Data ONTAP release and a diagnostic kernel in a single FAT partition. The CompactFlash card contains sufficient space for an upgrade kernel.
Note
FAS200 and FAS3000 series systems can be upgraded to the most recent Data ONTAP release. When you install new software, the download command copies a boot kernel to the CompactFlash card, not to a boot block on disk, as in other system models. For more information, see the Data ONTAP Upgrade Guide.
You can also enter one of the following boot options at the CFE (Common Firmware Environment) prompt:
- boot_ontap
Boots the current Data ONTAP software release stored on the CompactFlash card. By default, the storage system automatically boots this release if you do not select another option from the basic menu.
- boot_primary
Boots the Data ONTAP release stored on the CompactFlash card as the primary kernel. This option overrides the firmware AUTOBOOT_FROM environment variable if it is set to a value other than PRIMARY. By default, the boot_ontap and boot_primary commands load the same kernel.
- boot_backup
Boots the backup Data ONTAP release from the CompactFlash card. The backup release is created during the first software upgrade to preserve the kernel that shipped with the storage system. It provides a "known good" release from which you can boot the storage system if it fails to automatically boot the primary image.
- netboot
Boots from a Data ONTAP version stored on a remote HTTP or TFTP (Trivial File Transfer Protocol) server. Netboot enables you to
- Boot an alternative kernel if the CompactFlash card becomes damaged
- Upgrade the boot kernel for several devices from a single server
To enable netboot, you must configure networking for the storage system (using DHCP or static IP address) and place the boot image on a configured server.
Note
To protect against data loss in the event of PC CompactFlash card corruption, enable netboot immediately for your storage system by placing a boot image on a local server. For more information, see Preparing a storage system for netboot startup.
- boot_diags
Boots a Data ONTAP diagnostic kernel. For more information, see the Diagnostics Guide.
Note
Other boot options should be used only under the direction of technical staff.

Checking available Data ONTAP versions
By default, an FAS200 series storage system boots the current Data ONTAP release from the primary kernel. You might need to check the current booted kernel and other kernels available on the CompactFlash card if the storage system was started via netboot from an unfamiliar system, if an upgrade was unsuccessful, or if you need to run kernel diagnostics.
To determine...
|
At the storage system console, enter...
|
|
The current booted Data ONTAP version
|
version
Result
The console displays the version number of Data ONTAP that is currently running.
|
|
Data ONTAP versions available on the CompactFlash card
|
version -b

For more information, see the na_version(1) manual page.
Preparing a storage system for netboot startup
To use the netboot option to start your storage system, you must have
- An HTTP or TFTP server available on your network.
- A boot image on a server. The boot image can be copied from the system boot directory, /etc/boot/netapp-mips, or downloaded from the NetApp on the Web (NOW) site at http://now.netapp.com/.
Note
You can also store the boot image on another storage system.
- Networking configured in the FAS200 series or FAS3000 firmware environment. You can use a Dynamic Host Configuration Protocol (DHCP) server to obtain an IP address, or you can configure the network connection manually.
Note
Network interfaces configured in the firmware environment are not persistent across system halts and reboots. You must configure the network interface each time you use the netboot option.
Two network interfaces, e0a and e0b, are available in the firmware environment. Only one can be configured at a time.
Starting storage system through the netboot option
To boot Data ONTAP from a remote image for FAS200 or FAS3000 series systems, complete the following steps.
Step
|
Action
|
|
1
|
At the storage system console, enter the following command:
halt
|
|
2
|
If you are...
|
Then...
|
|
Configuring DHCP
|
Enter the following command at the CFE> prompt:
ifconfig e0a -auto
|
|
Configuring manual connections
|
Enter the following command at the CFE> prompt:
ifconfig e0a -addr=filer_addr
-mask=netmask -gw=gateway -dns=dns_addr
-domain=dns_domain
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. dns_domain is the Domain Name Service (DNS) domain name. If you use this optional parameter, you do not need a fully qualified domain name in the netboot server URL; you need only the server's host name).
Note Other parameters might be necessary for your interface. Enter help ifconfig at the firmware prompt for details.
|
|
3
|
At the CFE> prompt, enter the following command:
netboot URL
URL is the location of the remote boot image. It can be either an HTTP or a TFTP network path.
Examples:
netboot http://myserver/bootimages/netapp/netapp-mips
netboot tftp://myserver/bootimages/netapp/netapp-mips
Note The location and availability of boot images depend on the correct configuration of your netboot server.
