Skybox version 8.5.400

Chapter 7
In some cases, it may be necessary to update the CentOS operating system on
your Skybox Appliance, such as when bug fixes or security patches are released
for the operating system.
Updates to the operating system do not affect Skybox.
Before you start the update
Both the Skybox model and important system files can be saved as part of the
update procedure, or you can save them manually beforehand. Changes that you
made manually in any files are not saved as part of the update, so you must
back them up manually.
Note that the machine reboots as part of the update process.
To update the operating system
1
Download the following files to your computer (not to the Appliance server).
•
Skybox_<patch #>.appliance_update
•
Skybox_<patch #>appliance_update.md5
2
Copy
Skybox_<patch #>.appliance_update
to the Appliance server using
Secure Copy Protocol (SCP).
3
Copy
Skybox_<patch #>.appliance_update.md5
to the same directory using
SCP.
4
Connect to the Appliance server via SSH using root credentials.
5
Navigate to the directory where the files were saved.
6
Verify that the update file was copied without any mistakes using the md5sum
command:
•
md5sum -c Skybox_<patch #>.appliance_update.md5
The output should be:
Skybox_<patch #>.appliance_update: OK
7
Run the following command to install the update:
•
/bin/sh Skybox_<patch #>.appliance_update
The update procedure begins.
8
We recommend that, when asked where to save the files, you select either a
location on the file sharing system (as opposed to on the Appliance server
itself) or an external drive.
9
Restore the files that you saved manually.
