As an Appliance Administrator, you can use the Managed Networks page to search for an IP address within a managed network's list of subnets.
To find an IP address in a managed network
- Go to Managed Networks:
- web client: Navigate to Cluster > Managed Networks.
-
In the Resolve Network search box, type the IP address, and press Enter.
The managed network that contains the subnet that most closely matches the IP address is highlighted. If there are no subnets that match the IP address, the Default Managed Network is highlighted.
To reduce potential downtime, the Appliance Administrator can configure Offline Workflow Mode to be performed automatically. Offline Workflow Mode allows an appliance that has lost consensus (quorum) to operate in isolation from the cluster to process access requests using cached policy data.
To ensure the outage is not a short-lived outage, the default time before the appliance is automatically switched to Offline Workflow Mode is 15 minutes. The time threshold can be changed to five minutes or more.
If automatic Offline Workflow Mode is enabled, you can enable automatic Resume Online Workflow so the appliance automatically resumes online operations once consensus is restored. The minutes to wait after consensus is restored before automatically resuming online workflow defaults to 15 minutes. The time threshold can be changed to five minutes or more.
When Offline Workflow Mode settings are configured to run automatically, an Appliance Administrator can override the automatic settings and manually place an appliance in Offline Workflow Mode or manually restore an appliance to online workflow, as needed.
The user views status messages that clearly communicate the appliance state and the ability to request passwords and SSH keys.
For general information on Offline Workflow Mode, see About Offline Workflow Mode.
Go to Offline Workflow:
- web client: Navigate to Cluster > Offline Workflow.
The Offline Workflow page displays the following information.

Use the Offline Workflow page to configure automatic settings to control Offline Workflow Mode. You can manually override the automatic settings. For more information, see Manually override automatic Offline Workflow.
To configure automatic settings to control Offline Workflow Mode
- Go to Offline Workflow:
- web client: Navigate to Cluster > Offline Workflow.
- On the Offline Workflow dialog, select Enable Automatic Offline Workflow so the appliance will be automatically placed in Offline Workflow Mode when the appliance loses connection and cannot establish consensus with the cluster for the specified number of minutes entered (see next step).
- Identify the number of Minutes after consensus is lost before the appliance is automatically switched over to Offline Workflow Mode. The Automatic Offline Workflow Threshold defaults to 15 minutes and can be changed to a minimum of five minutes or more.
- If you selected the first check box to enabled automatic Offline Workflow Mode, you can select Automatic Resume Online Workflow so the appliance automatically resumes online operations once consensus with the cluster is restored for the specified number of minutes entered (see next step).
- Identify the number of Minutes after consensus is restored that the appliance is automatically switched over to online workflow. The Automatic Resume Online Workflow Threshold defaults to 15 minutes and can be changed to a minimum of five minutes or more.
- Click Save.
Use the Offline Workflow page to manually enable offline workflow or resume online operations.
For details on either of these operations, see Manually control Offline Workflow Mode.
Before resuming online operations, see Considerations to resume online operations.
