JSA Vulnerability Manager High-availability Scans
Use a JSA high-availability (HA) deployment to maintain your vulnerability scanning schedule, if your primary JSA deployment fails.
High-availability (HA) version 2 is supported in JSA Vulnerability Manager.
You must use identical appliances with identical software configurations in your high-availability (HA) setup. For information about setting up a high-availability (HA) deployment, see the Juniper Secure Analytics High Availability Guide.
High Availability (HA) Scans
The following appliances are supported in a JSA Vulnerability Manager high-availability (HA) deployment:
Scanner appliance (610)
Processor appliance (600)
Take note of the following information when you deploy high availability (HA) vulnerability scanning:
Cancel and restart any in-progress scans after a failover if the scans were in progress during the failover.
If you replace an appliance in your HA scanning environment, it might not appear in the deployment. You must re-add the appliance to the HA deployment, and then deploy changes.
Use identical appliances and configurations in your high availability (HA) setup.
Auto updates do not resume after a failover. You must run an auto update in an uninterrupted active setup.
