6.5 HP StoreAll 8200/9300 Storage Administrator Guide

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
Other host group operations
Additional host group operations are described in the following locations:
• Creating or deleting a mountpoint, and mounting or unmounting a file system (see "Creating
and mounting file systems" in the HP StoreAll OS User Guide).
• Changing host tuning parameters (see “Tuning nodes and StoreAll clients” (page 98))
• Preferring a network interface (see “Preferring network interfaces” (page 109))
• Setting allocation policy (see "Using file allocation" in the HP StoreAll OS User Guide.).
Add preferred NIC
By default, clients and segment servers use the cluster interface. Use this dialog to select a user
interface to carry the traffic from a host group to a specific server. When you prefer a user interface
for traffic from a source host to a destination host, traffic in the reverse direction remains defaulted
to the cluster interface.
The Add Preferred NIC dialog box contains the following fields:
DescriptionField
The server that will be receiving traffic via the preferred NIC.Server name
The network NIC that will carry traffic from the clients in the host group to
the selected server.
Interface name
Modify host group properties
Use this dialog box to modify properties of host group clients and servers. Under the General tab,
you can select host groups, specify the number of Admin and Server threads, select a protocol
(TCP or UDP) and define a domain. Under the Advanced tab, you can specify module tune options.
For more information, see the HP StoreAll OS User Guide and the HP StoreAll OS CLI Reference
Guide.
Mount a file system to a host group
Use this dialog to mount a files system on all clients belonging to the selected host group. For each
client, the files system is mounted when the client queries the Management Server for its mountpoints
or is rebooted.
