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.
Managing the FluidFS Cluster Name
The FluidFS cluster name is a unique name used to identify the FluidFS cluster in Storage Manager and the name that clients use to
access the FluidFS cluster. This name is also the FluidFS cluster NetBIOS name.
If clients access the FluidFS cluster by name (instead of IP address), you must add an entry in the DNS server that associates the FluidFS
cluster name to the FluidFS cluster client VIPs. If you are using multiple client VIPs, add all client VIPs to the DNS server and associate
them with the same FluidFS cluster name (known as round-robin DNS). This association enables client load balancing between client VIPs.
View the FluidFS Cluster Name
View the current FluidFS cluster name that is displayed in Storage Manager and the name that clients use to access the FluidFS cluster.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the Summary tab. The FluidFS cluster name is displayed below the tab.
Rename the FluidFS Cluster
Changing the FluidFS cluster name changes the FluidFS cluster name that is displayed in Storage Manager and the name that clients use
to access the FluidFS cluster.
Prerequisites
After changing the FluidFS cluster name, you must also make the following adjustments:
• Change the FluidFS cluster name on the DNS server.
• If the FluidFS cluster is joined to an Active Directory domain, leave and then rejoin the FluidFS cluster to the Active Directory domain. If
the FluidFS cluster is joined to Active Directory using the old FluidFS cluster name, it might affect the ability of Active Directory users
to access the system.
Steps
1. Click the Storage view, select a FluidFS cluster.
2. Click the Summary tab.
3. In the FluidFS Cluster Status panel, click Edit FluidFS Cluster Settings. The Edit FluidFS Cluster Settings dialog box opens.
