HP XP Racks - Manual (Page 176)

register HP-UX hosts to the corresponding host group and register Windows hosts to the other host
group.
NOTE: The above example relates to configurations in which all HP-UX hosts are on the same
cluster.
Before you can set LU paths, you must register the hosts in host groups. For example, if HP-UX hosts
and Windows hosts are connected to a port, register HP-UX hosts and Windows hosts separately
in two different host groups.
When registering a host, you must also specify the WWN of the host bus adapters.
When registering hosts in multiple host groups, set the security switch (LUN security) to enabled,
and then specify the WWN of the host bus adapter.
When registering a host, you can assign a nickname to the host bus adapter. If you assign a
nickname, you can easily identify each host bus adapter in the LUN Manager window. Although
WWNs are also used to identify each host bus adapter, the nickname that you assign will be more
helpful because you can name host bus adapters after the host installation site or for the host
owners.
1.
Display the Create Host Groups window by performing one of the following:
•
In Remote Web Console, select Create Host Groups from the General Tasks menu and
display the Create Host Groups window.
•
From the Actions menu, choose Ports/Host Groups, and then Create Host Groups.
•
From the Storage Systems tree, click the Ports/Hosts Groups. In the Host Groups page of
the displayed window, click Create Host Groups.
•
From the Storage Systems tree, expand the Ports/Hosts Groups node, and then click the
relevant port. In the Host Groups page of the displayed window, click Create Host Groups.
2. Enter the host group name in the Host Group Name box.
•
It is convenient if you name each host group after the host platform.
•
A host group name can consist of up to 32 ASCII characters (letters, numerals, and
symbols). However, you cannot use the following symbols for host group names: \ / : ,
; * ? " < > |
•
You cannot use space characters for the first and the last characters in host group names.
•
Host group names are case-sensitive. For example, the host group names wnt and Wnt
represent different host groups.
3. Select the resource group in which a host group is created.
If you select Any, ports to which you may add host groups within all ports assigned to a user
are displayed in the Available Ports list. If you select other than Any, ports to which you may
add host groups within the ports assigned to the selected resource group are displayed in the
Available Ports list.
4. Select a host mode from the Host Mode list. When selecting a host mode, you must consider
the platform and some other factors.
5. Select hosts to be registered in a host group.
If the desired host has ever been connected with a cable to another port in the storage system,
select the desired host bus adapter from the Available Hosts list.
If there is no host to be registered, skip this step and move to the next step. Otherwise, a host
group with no host would be created.
If the desired host has never been connected via a cable to any port in the storage system,
perform the following steps:
