Upgrading to a single-node FAS270

About upgrading the FAS250

Upgrading the FAS250 is a four-step process:

Assumptions about the upgrade

These procedures assume the following:

  • You have access to an HTTP server for the netboot process.
  • You backed up your FAS250 system before beginning the conversion procedure.

Preparing the FAS250

To prepare the FAS250 for upgrade to a FAS270, complete the following steps.

Step Action

1

Check the Media Kit in the FAS270 packaging for the version level of Data ONTAP to be installed on the FAS270. Compare it to the version level of Data ONTAP that is installed on the FAS250.

2
If Data ONTAP on the FAS250 is...
Then...

The same as or a later version than the FAS270

Go to Preparing for the netboot process.

An earlier version than the FAS270
  1. Download Data ONTAP to a client or Web server from http://now/netapp.com/NOW/main/software.shtml.
  2. Extract and install the files by entering one of the following commands from the console:
software install software_file

or

software install url

software_file is the name of the file on the CPU module.

url is the location of the software in a Web server.

Note: In a Windows® environment, you must unzip the files and run setup.exe.

  1. Download the image by entering the following command:
download
  1. Reboot the system.

Preparing for the netboot process

The FAS270 node is shipped without an image on its CompactFlashTM card. After installing the new FAS270 node, you must perform a netboot process on Data ONTAP so that you can download the correct files to the CompactFlash card for subsequent system boots.

The two main methods of performing the netboot process are as follows:

  • Through an HTTP server with DHCP running
  • Through a TFPT server, manually setting ifconfig

To copy the Data ONTAP boot image to a local HTTP server for the netboot process, complete the following steps.

Step Action
1

Copy the netapp-mips file from the /etc/boot directory on the FAS250 and copy it to a Web server that can access the FAS250.

Note: You can also copy this file from http://now/netapp.com/NOW/main/software.shtml to your local Web server.
2

Halt the system by entering the following command:

halt

Note: The system begins beeping two minutes after Data ONTAP stops.
3
If DHCP is...
Then...
Running

Configure the connection automatically by entering the following command at the CFE prompt:

ifconfig e0a -auto
Not running

Manually configure the connection by entering the following command at the CFE prompt:

ifconfig e0a -addr= filer_addr -mask= netmask -gw= gateway \
-dns= dns_addr -domain= dns_domain

4

Test the netboot process by entering the appropriate command from the node console:

Automatically use the netboot process through the HTTP server:
netboot http:// webserver.com / file_path / netboot_file_name
Manually use the netboot process through the TFTP server:
netboot tftp:// webserver.com / file_path / netboot_file_name

webserver.com is the name of the Web server where you copied the netboot file.

file_path is the path to the netboot file.

netboot_file_name is the name of the netboot file.

See Help netboot for more information.

Converting the hardware

To convert the FAS250 hardware, complete the following steps, using the illustration for reference.

Step Action

1

Halt the system, turn off the power to the FAS250, and remove all cabling from the system. Make sure that you are properly grounded.

2

Remove the FAS250 node and replace it with the new FAS270 node.

3

Connect the system to the network through port A on the on-board Ethernet adapter, and then recable the console and reconnect the system to the power source.

4

Set the terminate switch on the node to On.

5

Go to Completing the upgrade.

Upgrading to a FAS270c

About upgrading to a FAS270c

Preparing the FAS270 for upgrade to a cluster is a two-step process:

Assumptions for upgrading to a FAS270c

This procedure assumes the following:

  • You completed the upgrade from a FAS250 to a single CPU FAS270, as described in Upgrading to a single-node FAS270.
  • You have four spare disks; one for the first node, Node B, two for root volumes on Node A (the second node), and one spare for Node A.
  • Node B owns the current file system.
  • A second console is attached to Node A.
  • You scheduled system down time to upgrade an active system.

What the system looks like

The following illustration shows the arrangement of the individual nodes in a FAS270c.

Disk reservation and ownership worksheet

Use the following worksheet to identify disk ownership in your system. You should note the location of root and data volumes and the location of unused or unassigned disks. Node A is not initially installed in the system. It is installed in Preparing Node A.

You must have four spares available:

  • One spare for Node B
  • Two spares for root volumes on Node A
  • One spare for Node A

If all disks are full on Node B or there are not enough spare disks on the system, you must add a disk shelf or disk shelves to the system, as described in Adding storage.
