Uncompressing and installing system files from a UNIX host

Uncompressing the files

The system files you downloaded are in compressed format. You must uncompress the files before you can use them.

Complete the following steps to uncompress and check the system files, replacing filename.z in the procedure with the name of the file you downloaded.

Step Action
1

Uncompress the files with names that end with .z:

uncompress filename.Z ...
2

Verify the lengths and checksums of the downloaded files.

ls -l filename ...

In the actual command, substitute the name of the file for filename. (After a file has been uncompressed, its name does not have the .z extension.)

3

Compare the length reported by the ls command with the value shown in the NOW page.

sum filename ...

In the actual command, substitute the name of the file for filename. Compare the checksum you compute with the value shown in the NOW page.

If the values do not match, the compressed file might have become corrupted when you downloaded it. Start the upgrade process again using the instructions in "Downloading the software."

Installing the files

Complete the following steps to install the system files on your filer.

Note: Replace the variable filer with the host name of your filer; replace the variable full_path_to_file with the full path of the system file that you downloaded and uncompressed.

Step Action
1 Enter the following commands at the filer's administration host: 
mount filer:/ /mnt

cd /mnt

tar xvf full_path_to_file
Example
If your filer is named toaster and you saved the uncompressed system file named 1.2.3_tar_floppy_pc in the /tmp directory, enter the following commands at the administration host: 
mount toaster:/ /mnt

cd /mnt

tar xvf /tmp/1.2.3_tar_floppy_pc
Results
The files install_netapp and tar_image.z are extracted.
2 On the filer's administration host, run the install_netapp script with an argument that tells the script where to install the files; that is, to the mount point for the filer's root directory: 
./install_netapp /mnt
Results
The install_netapp script uncompresses the image file, installs it, and then deletes the temporary files it has used, while displaying a transcript of its actions.
3 Enter the following commands at the filer's administration host to unmount the filer's root file system: 
cd /

umount /mnt
Results
The filer's root file system is unmounted from the administration host.
4 Remove the compressed and uncompressed system files from the administration host.
5 Enter the following command at the filer's command prompt to copy the executable file to the hard disk boot area of each of the filer's disks: 
download

Note: You can enter the command either at the filer console or from a telnet connection to the filer.

Results
When the executable file has been copied to the filer's disks, the command prompt reappears--the download command displays a series of dots showing the progress and a message that the download has completed.
6 Enter the following command at the filer's command prompt to reboot the filer: 
reboot
Results
The filer console displays the copyright notice followed by the Data ONTAP release number. The software upgrade is complete.
