Prior to performing an upgrade, you can create a snapshot of the engine that
you can revert to in the event an upgrade fails. Refer to the vSphere client
documentation for instructions on creating a snapshot.
1. On a system with an Internet connection, go to the Network Management Suite
(NMS) Download web page:
http://extranet.extremenetworks.com/downloads/pages/NMS.aspx.
2. After entering your email address (username) and password, follow this path to the
download page: Visibility & Control > Network Management Suite (NMS) > Software
> select a version.
3. Download the following ExtremeAnalytics virtual engine file from the NMS
Downloads section:
purview_appliance_upgrade_to_version.bin
4. Use FTP, SCP, or a shared mount point, to copy the file to the ExtremeAnalytics
virtual engine.
5. SSH to the engine.
6. Cd to the directory where you downloaded the files.
7. Change the permissions on the upgrade file by entering the following command:
chmod 777 purview_appliance_upgrade_to_version.bin
8. Run the install program by entering the following command:
./purview_appliance_upgrade_to_version.bin
The upgrade automatically begins. You are notified when the upgrade
completes.
Reinstalling ExtremeAnalytics Engine Software
In the event that a software reinstall becomes necessary, it is recommended that
you restore an engine snapshot that you previously made using the vSphere
client. Refer to the vSphere client documentation for instructions on restoring a
snapshot.
If you do not have an engine snapshot to restore, you will need to re-deploy and
reconfigure the ExtremeAnalytics virtual engine following the instructions in
Engine Deployment and this section.
Note: The re-installation procedure reformats the hard drive, reinstalls all
the ExtremeAnalytics engine software, the operating system, and all
related Linux packages.
