By default, HA takeover occurs only if the primary node stops working or becomes unreachable from the secondary node. However, this does not cover the scenario when the primary node becomes unaccessible to the outside world while the secondary node would be still accessible (for example because it is connected to a different router).
To address such situations, you can specify IP addresses (usually next hop routers) to continuously monitor both the primary node and the secondary node by using ICMP echo (ping) messages. One such address can be set up for every interface.
When setting up next hop monitoring, you have to make sure that the primary and secondary nodes can ping the specified address directly. You can either:
Choose the addresses of the redundant-HA One Identity Safeguard for Privileged Sessions (SPS) interfaces so that they are on the same subnet as the next-hop address
Configure the next-hop device with an additional IP-address that is on the same subnet as the redundant-HA SPS interfaces facing it
If any of the monitored addresses becomes unreachable from the primary node while being reachable from the secondary node (in other words, more monitored addresses are accessible from the secondary node) then it is assumed that the primary node is unreachable and a forced takeover occurs — even if the primary node is otherwise functional.
Naturally, if the secondary node is not capable of taking over the primary node (for example, because there is data not yet synchronized from the current primary node), no takeover is performed.
To configure next hop monitoring
Navigate to Basic Settings > High Availability > Next hop monitoring.
Select the interface to use for monitoring its next-hop router.
Figure 125: Basic Settings > High Availability — Configuring next hop monitoring
Enter the IP address to monitor from the current primary node (for example, the IP address of the router or the switch connected to the interface) into the This node > Next hop IP field of the selected interface. This IP address must be a real IP address that is visible from the interface, and must be on the same local network segment.
Use an IPv4 address.
Enter the IP address to monitor from the current secondary node (for example the IP address of the router or the switch connected to the interface) into the Other node > Next hop IP field of the selected interface. This IP address must be a real IP address that is visible from the interface, and must be on the same local network segment.
Use an IPv4 address.
Repeat the previous steps to add IP addresses to be monitored from the other interfaces if needed.
For the changes to take effect, you have to restart both nodes. To restart both nodes, click Reboot Cluster.
One Identity Safeguard for Privileged Sessions (SPS) appliances are preinstalled with a Long Term Support (LTS) release. One Identity recommends that you upgrade to the latest LTS maintenance release as soon as possible. Each LTS release is supported for 3 years after original publication date, and for 1 year after the succeeding LTS release is published (whichever date is later). You are encouraged to upgrade to succeeding LTS releases.
Feature Releases provide additional features which are not yet consolidated to an LTS release. To gain access to these features, you may install a supported Feature Release on the appliance, with the following conditions:
You cannot roll back to an LTS release from a Feature Release.
Feature Releases are released and supported in a timeline of 6 months. You have to keep upgrading SPS to the latest Feature Release to ensure that your appliance is supported.
For both LTS and Feature Releases, One Identity regularly incorporates security patches and bugfixes, and issues updated Revisions of the released product. One Identity strongly recommends always installing the latest Revision of the used software Release.
Downgrading from the latest Feature Release, even to an LTS release, voids support for SPS.
The following sections describe how to keep SPS up to date, and how to install a new license:

Exporting the configuration of One Identity Safeguard for Privileged Sessions (SPS)
Importing the configuration of One Identity Safeguard for Privileged Sessions (SPS)
The following list applies to all configurations:
You have created a configuration backup of One Identity Safeguard for Privileged Sessions (SPS).
For detailed instructions, refer to Exporting the configuration of One Identity Safeguard for Privileged Sessions (SPS).
You have a valid support portal account.
To download the required firmware file and license, you need a valid support portal account. Note that registration is not automatic, and might require up to two working days to process.
You have downloaded the latest SPS firmware from the Downloads page.
You have read the Release Notes of the firmware before updating. The Release Notes might include additional instructions specific to the firmware version.
The Release Notes are available at the Downloads page.
You have verified that SPS is in good condition (no issues are displayed on the System Monitor).
Optional: You have exported core dump files, if necessary for debugging, from Basic Settings > Troubleshooting > Core files. These files are removed during upgrade.
If you have a High Availability cluster:
You have IPMI access to the secondary node. You can find detailed information on using the IPMI in the following documents:
For Safeguard Sessions Appliance 3000 and 3500, see the X9 SMT IPMI User's Guide.
You have verified on the Basic Settings > High Availability page that the HA status is not degraded.
If you are upgrading SPS in a virtual environment:
You have created a snapshot of the virtual machine before starting the upgrade process.
You have configured and enabled console redirection (if the virtual environment allows it).
During the upgrade, SPS displays information about the progress of the upgrade and any possible problems in the following places:
On the web interface of SPS, at any of the Listening addresses configured at Basic settings > Local Services > Web login (admin and user). (After booting, you are directed to the login screen of SPS.)
NOTE: If you are upgrading to version 6.9.3 from version 5.0.x, this feature is enabled after the first boot to version 6.9.3. So during the upgrade to version 6.9.3, you will not be able to see any upgrade logs on the web interface.
On the console, which you can monitor with IPMI (ILOM) or console access.
The information displayed in the browser and on the console is the same.
One Identity strongly recommends that you test the upgrade process in a non-production (virtual, and so on) environment first.
Upgrading SPS requires a reboot. We strongly suggest that you perform the upgrade on the production appliance during maintenance hours only, to avoid any potential data loss.
The following describes how to upgrade One Identity Safeguard for Privileged Sessions (SPS) to a newer firmware version. To upgrade SPS without using the web interface, see Firmware update using SSH. One Identity recommends that you always use the latest maintenance release available.
When upgrading to a new major release (that is, to a new Feature Release or a new Long-Term Supported release), always follow the instructions of the How to upgrade to One Identity Safeguard for Privileged Sessions guide for that release, as it contains more detailed instructions (available at the Safeguard for Privileged Sessions Documentation page).
To upgrade SPS to a newer firmware version
Navigate to Basic Settings > System > Firmwares.
Figure 126: Basic Settings > System > Firmwares — Managing the firmwares
