Note
If you are adding a Samba-service resource, connect a Samba-service resource
directly to the service, not to a resource within a service.
6. If you want to add resources to that resource, click Add a child. Clicking Add a child causes
the display of additional options to local and global resources. You can continue adding children
resources to the resource to suit your requirements. To view children resources, click the triangle
icon to the left of Show Children.
7. When you have completed adding resources to the service, and have completed adding children
resources to resources, click Submit. Clicking Submit causes a progress page to be displayed
followed by a page displaying the added service (and other services).
Note
To verify the existence of the IP service resource used in a cluster service, you must use
the /sbin/ip addr list command on a cluster node. The following output shows the
/sbin/ip addr list command executed on a node running a cluster service:

3.10. Configuring Cluster Storage

To configure storage for a cluster, click the storage tab. Clicking that tab causes the display of the
Welcome to Storage Configuration Interface page.
The storage tab allows you to monitor and configure storage on remote systems. It provides a
means for configuring disk partitions, logical volumes (clustered and single system use), file system
parameters, and mount points. The storage tab provides an interface for setting up shared storage for
clusters and offers GFS and other file systems as file system options. When a you select the storage
tab, the Welcome to Storage Configuration Interface page shows a list of systems available to
the you in a navigation table to the left. A small form allows you to choose a storage unit size to suit
your preference. That choice is persisted and can be changed at any time by returning to this page.
In addition, you can change the unit type on specific configuration forms throughout the storage user
interface. This general choice allows you to avoid difficult decimal representations of storage size (for
