Enable or Disable Secured Management

Enable secured management to exclusively limit management traffic to one specific subnet.

Prerequisites

  • The subnet on which you enable secured management must exist before you enable the secured management feature.

  • The FluidFS cluster must be managed by Storage Manager using the subnet on which secured management will be enabled. To manage the FluidFS cluster on the secured management subnet, remove the FluidFS cluster from Storage Manager and then re-add the FluidFS cluster to Storage Manager using the secured management subnet management VIP.

About this task

After enabling secured management, if you are connected to Storage Manager through the secured management subnet, your management session is temporarily interrupted while the change takes effect. During this time, the following message is displayed in Storage Manager:

Communication with the cluster was interrupted in process of issuing a command that performs modification to the cluster .

After the change takes effect, your management session will resume automatically. Management sessions on all other subnets are disconnected.

Disable secured management to allow management traffic from any subnet.

Steps

  1. In the Storage view, select a FluidFS cluster.
  2. Click the File System tab.
  3. In the File System view, select Cluster Connectivity and then click the Management Network tab.
  4. In the Management Network panel, click Edit Settings. The Modify Administrative Network dialog box opens.
  5. Enable or disable secured management. From the State drop-down list:
    • To enable secured management, select Restricted or Unrestricted.
    • To disable secured management, select Disabled.
  6. Click OK.
