The Select a Node panel will appear. Here you should select the owner node of
the NAS volume to be created. We select FLJ1 now (Figure 9-12). Click Next to
Figure 9-12 Select a Node
The volume selection panel will appear, as shown in Figure 9-13. The disks listed
here are physical volumes found on the shared storage.
We select hdisk2 and click Add. Click Next to continue.
Important: If you have created non-shared logical drives for the NAS
Gateway 500 nodes on the external storage system, the logical drives may
also be listed as hdisk devices in the Logical Volumes pane. With the Initial
Configuration wizard, you have no way to find out which one is a shared
logical drive and which one is not. If you select a non-shared logical drive to
create a NAS volume in a cluster configuration, the Initial Configuration wizard
will report an error.
To avoid this problem, you may need to login to the NAS Gateway 500 nodes
through a serial terminal with the root account, and use storage system
specified tools to identify which hdisk device is a shared logical disk.

The volume configuration panel will appear, as shown in Figure 9-14.
Keep in mind that a NAS volume is a file system on the shared storage. NAS
management tools automatically create and manage the volume group and other
underlying structures for these file systems.
We type in volnfs as the volume name and select the “Export the volume as an
NFS share” check box.
