Auto Update Server Support in Failover Configurations
c. If both units have new image, the secondary (standby) unit is reloaded first.
– If hitless upgrade can be performed when secondary unit boots, then the secondary unit becomes
the active unit and the primary unit reloads. The primary unit becomes the active unit when it
has finished loading.
– If hitless upgrade cannot be performed when the standby unit boots, then both units reload at
the same time.
d. If only the secondary (standby) unit has new image, then only the secondary unit reloads. The
primary unit waits until the secondary unit finishes reloading.
e. If only the primary (active) unit has new image, the secondary unit becomes the active unit, and
the primary unit reloads.
f. The update process starts again at Step 1.
5. If the ASA determines that the ASDM file needs to be updated for either the primary or secondary
unit, the following occurs:
a. The primary unit retrieves the ASDM image file from the HTTP server using the URL provided
by the Auto Update Server.
b. The primary unit copies the ASDM image to the standby unit, if needed.
c. The primary unit updates the ASDM image on itself.
d. The update process starts again at Step 1.
6. If the primary unit determines that the configuration needs to be updated, the following occurs:
a. The primary unit retrieves the configuration file from the using the specified URL.
b. The new configuration replaces the old configuration on both units simultaneously.
c. The update process begins again at Step 1.
7. If the checksums match for all image and configuration files, no updates are required. The process
ends until the next poll time.
Monitoring the Auto Update Process
You can use the debug auto-update client or debug fover cmd-exe commands to display the actions
performed during the Auto Update process. The following is sample output from the debug auto-update
client command.
