Accomplish the following steps to switch to GRHA mode:
- Upgrade the SBC application either using LSWU or Platform Manager.
As user root, stop the standby server using the following command:
| Code Block |
|---|
|
# service sbx stop |
| Note |
|---|
The services on standby SBC server must be stopped before switching to GRHA mode since the switch to GRHA mode causes a temporary HA link outage. The script will verify the state of the servers and make the necessary changes. |
From the CLI command prompt, perform one of the steps below, depending on your configuration. For example, in SBC Core, set bond monitoring type to network-connect and leader election algorithm type to enhanced:
| Code Block |
|---|
> request system admin sbx1 setHaConfig bondMonitoring network-connect leaderElection enhanced |
Verifying GRHA Mode
Accomplish the following step to verify GRHA mode:
| Code Block |
|---|
|
> show table system haConfig

Switching Out of the GRHA Mode
To set bond monitoring type to direct-connect and leader election algorithm type to standard, enter the following command:
| Code Block |
|---|
> request system admin sbx1 setHaConfig bondMonitoring direct-connect leaderElection standard |
On the standby server, execute the following command:
| Code Block |
|---|
|
# geoRedundHa.sh enable |
On the active server, execute the following command:
| Code Block |
|---|
|
# geoRedundHa.sh enable |
...
| Code Block |
|---|
|
# service sbx start |
| Note |

The standby server comes up and reconnects as standby with the GRHA mode enabled on both the machines. |
