How Secure Access Updates Your Virtual Appliance
You can configure updates for the VAs in your organization. Secure Access makes API requests from each VA and pushes out software updates. If you wish to update a specific VA first, do this manually. For more information, see Manually Configure Update of a Virtual Appliance.
Logic is built-in to our API to prevent two VAs at a single site from updating at once or updating when one of the VAs is in an error state. The following checks are performed:
Procedure
| 1 |
The API checks if there is only a single VA for the site. If there is only one VA, the API does not offer a command to auto-update. |
| 2 |
If there is a secondary VA for the site but it is in an error state, then the first VA will not auto-update. |
| 3 |
The API checks to see if a second VA for that site is already updating and if it is in a mid-update state it will not auto-update during that window of time. If we have ordered a VA to update and have not heard back that it has completed, this qualifies as a mid-update state. |
| 4 |
If all the prerequisite checks have been met, the VA is updated. |
