Upgrading USM Appliance
To upgrade USM Appliance
-
Connect to the AlienVault Console on the secondary node through SSH and use your credentials to log in.
The AlienVault Setup menu displays.
- Update the node by selecting System Preferences > Update AlienVault System > Update System.
-
Press Enter (<Yes>) and wait until you see the following message:
Your system has been updated successfully
- Press Enter (<OK>).
-
On the AlienVault Setup main menu, select Jailbreak System to gain command line access.
Select Yes when prompted. You will be in the root directory.
-
Edit /etc/ossim/ossim_setup.conf and set ha_heartbeat_start=yes.
Note: You need to do this step because ha_heartbeat_start was set to no when disabling HA before the update.
- Repeat steps #1 through #6 on the primary node.
-
Re-enable HA.
Run this command first on the secondary node, then on the primary node:
screen alienvault-ha-assistant -e
Note: Use screen to keep the process running in the background even when the session disconnects.
-
(If and only if upgrading the Standard Sensors) On the primary node, swap the token with the secondary node, effectively making the primary node active:
alienvault-ha-assistant –w
