For example, suppose that you want all clients to be able to mount file system
ifs1
and to
implement a set of host tunings denoted as Tuning 1, but you want to override these global settings
for certain host groups. To do this, mount
ifs1
on the
clients
host group,
ifs2
on host group
A,
ifs3
on host group C, and
ifs4
on host group D, in any order. Then, set Tuning 1 on the
clients
host group and Tuning 2 on host group B. The end result is that all clients in host group
B will mount
ifs1
and implement Tuning 2. The clients in host group A will mount
ifs2
and
implement Tuning 1. The clients in host groups C and D respectively, will mount
ifs3
and
ifs4
and implement Tuning 1. The following diagram shows an example of these settings in a host
group tree.
To create one level of host groups beneath the root, simply create the new host groups. You do
not need to declare that the root node is the parent. To create lower levels of host groups, declare
a parent element for host groups. Do not use a host name as a group name.
Select
Create
on the Hostgroups window. The Create Hostgroup dialog box appears. When
entering the name of the host group, use only alphanumeric characters. The underscore character
(_) is also supported. Select the parent host group and enter a domain, if applicable. Click
OK
when finished.
Adding a StoreAll client to a host group
You can add a StoreAll client to a host group or move a client to a different host group. All clients
belong to the default
clients
host group.
Select Hostgroups in the upper Navigator. Under Summary in the lower Navigator, select Members.
Click
Add
on the Members panel to open the Add Members to Hostgroup dialog box. Click
OK
when you have finished.
Adding a domain rule to a host group
To configure automatic host group assignments, define a domain rule for host groups. A domain
rule restricts host group membership to clients on a particular cluster subnet. The Fusion Manager
uses the IP address that you specify for clients when you register them to perform a subnet match
and sorts the clients into host groups based on the domain rules.
Setting domain rules on host groups provides a convenient way to centrally manage mounting,
tuning, allocation policies, and preferred networks on different subnets of clients. A domain rule
is a subnet IP address that corresponds to a client network. Adding a domain rule to a host group
restricts its members to StoreAll clients that are on the specified subnet. You can add a domain
rule at any time.
To add a domain rule to a host group, use the
ibrix_hostgroup
command as follows:
ibrix_hostgroup -a -g GROUPNAME -D DOMAIN
For example, to add the domain rule
192.168.10.10
to the
finance
group:
ibrix_hostgroup -a -g finance -D 192.168.10.10
70
