6.2 HP IBRIX 9300/9320 Storage Administrator Guide (AW549-96049, December 2012)

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.
To create a host group tree using the CLI:
1. Create the first level of the tree:
ibrix_hostgroup -c -g GROUPNAME
2. Create all other levels by specifying a parent for the group:
ibrix_hostgroup -c -g GROUPNAME [-p PARENT]
Adding an 9000 client to a host group
You can add an 9000 client to a host group or move a client to a different host group. All clients
belong to the default clients host group.
To add or move a host to a host group, use the ibrix_hostgroup command as follows:
ibrix_hostgroup -m -g GROUP -h MEMBER
For example, to add the specified host to the finance group:
ibrix_hostgroup -m -g finance -h cl01.hp.com
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 9000 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 to the finance group:
ibrix_hostgroup -a -g finance -D 192.168
Viewing host groups
To view all host groups or a specific host group, use the following command:
ibrix_hostgroup -l [-g GROUP]
Deleting host groups
When you delete a host group, its members are reassigned to the parent of the deleted group.
