Deployment Guide

Add a Secured Management Subnet
The subnet on which you enable secured management must exist prior to enabling the secured management feature.
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. From the State drop-down list, select a state to be used for the management network.
• Select Restricted for management functionality to be blocked on other subnets
• Select Unrestricted for management functionality to be available on all subnets.
6. To change the prex of the network, type a prex length in the Prex eld.
7. In the Network ID eld, type the ID for the network that you want to modify.
8. Add one or more management VIPs through which the administrator manages the FluidFS cluster.
a. In the Virtual IP eld, type a management virtual IP address.
b. In the box for the Controller IP Address eld, type a controller IP address and click Add. Repeat this step for each
controller.
9. To specify a VLAN tag, type a VLAN tag in the VLAN Tag eld. When a VLAN spans multiple switches, the VLAN tag is used to
specify which ports and interfaces to send broadcast packets to.
10. From the Interface drop-down list, select the interface on which the secured management subnet is located.
• Select Admin to use the LOM Ethernet port for physical isolation of management trac. You must also connect a network
cable to the LOM Ethernet port of each controller in the rst (or only) appliance.
• Select Client for subnet-level isolation of management trac.
11. Click OK.
Enable or Disable Secured Management
Enable secured management to exclusively limit management trac to one specic 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 eect. 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 eect, your management session will resume automatically. Management sessions on all other subnets are
disconnected.
Disable secured management to allow management trac from any subnet.
Steps
1. In the Storage view, select a FluidFS cluster.
