Viewing host groups

To view clients that are members of a host group, select the host group in the Hostgroups window.
The member information displays in the Members panel in the lower half of the window. The
member information includes the name, IP address and Universal Unique Identifer (UUID) of the
client.

Deleting host groups

When you delete a host group, its members are reassigned to the parent of the deleted group.
Select the applicable host group on the Hostgroups window and click Delete. A message displays
asking you to confirm the deletion.
To force the reassigned StoreAll clients to implement the mounts, tunings, network interface
preferences, and allocation policies that have been set on their new host group, either restart
StoreAll software services on the clients or execute the following commands locally:
ibrix_lwmount -a to force the client to pick up mounts or allocation policies
ibrix_lwhost --a to force the client to pick up host tunings
