Adding a Node Group
Because a node in a Enterprise is always a member of a group, you must create node groups before defining nodes. Node groups enable you to define backups and privileges for many nodes at once. When you install DPX, a primary node group is created for the master server.
It is advantageous to create a separate node group for nodes connected using Network Data Management Protocol (NDMP nodes). Although DPX does not prevent you from having node groups containing both NDMP and non-NDMP nodes, there are limitations placed on NDMP nodes that make it difficult to properly define backups and privileges for a mixed group.
For any cluster, it is required that you create a dedicated node group.
To define a new Node Group:
To open the Configure Enterprise window, click the Configure tab on the Function Tab bar, then clicking or right-click Enterprise.
Open the Add node group dialog in the right pane by doing one of the following:
Right-click the Enterprise name or icon to display a context menu. The selection check box will appear full next to Enterprise icon, and the edit Enterprise dialog appears in the right pane. Then select Add Node Group.
In the left pane, select the Enterprise to which you want to add the node group.
From the menu bar, select Enterprise > Add Node Group.
On the task panel, click Add Node Group.
The Add Node Group dialog appears in the right pane.
Complete the active fields in the Add Node Group dialog:
Group Name
Enter a name for the node group (for example, SALES). You can use up to 48 alphanumeric characters, no spaces. Do not use the reserved string BMR.
Device Cluster Name
Select a device cluster (or tape library) from the pull-down menu. A device cluster is a set of storage devices, such as tape drives. If there are no device clusters or tape libraries in the pull-down menu, you can edit the node group later to add one.
The device cluster you select here is the default backup destination for nodes in the node group. During backups, DPX automatically chooses available devices in the default device cluster and prompts the operator for mounts.
When you define a backup, you can override this default device cluster, and you can also choose an individual destination device. However, it is usually preferable to accept the default device cluster and let DPX choose the destination device from that device cluster.
For NDMP node groups, it is best to choose an NDMP device cluster. For non-NDMP node groups, it is best to choose a non-NDMP device cluster. You could choose a SAN device cluster for either if it has both NDMP and non-NDMP devices.
Media Pool Name
Select a media pool from the pull-down menu. A media pool is a grouping of media volumes, such as tape cartridges. If there are no media pools in the pull-down menu, you can edit the node group later to add one.
The media pool you name here is the default pool for nodes in the node group. You can override this default media pool when you define backups.
