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.

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.
