The above example relates to configurations in which all HP-UX hosts are on the same cluster.Creating a host group and registering hosts in the host group (in a Fibre Channel environment)
The Storage Administrator (Provisioning) role is required to perform this task.
After discovering the WWNs of the host bus adapters, create a host group and register hosts in the host groups in a fibre channel environment.
You can connect multiple server hosts of different platforms to one port of your VSP G200, G400, G600 storage system. When configuring your storage system, you should group server hosts connected to the storage system by host groups. For example, if HP-UX hosts and Windows hosts are connected to a port, create one host group for HP-UX hosts and create another host group for Windows hosts. Then register HP-UX hosts to the corresponding host group and register Windows hosts to the other host group.
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, 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.
Perform one of following to display the Create Host Groups window.
For Hitachi Command Suite:
On the Resource tab, expand the Storage Systems tree. On the target storage system, click Port / Host Group. On the Host Groups / iSCSI Targets tab, click Create Host Groups.
For Storage Navigator:
On the General Tasks in Hitachi Device Manager - Storage Navigator, select Create Host Groups.
In the Storage Systems tree, click Ports / Hosts Groups / iSCSI Targets. In the Host Groups / iSCSI Target tab, click Create Host Groups.
In the Storage Systems tree, click Ports / Hosts Groups / iSCSI Targets, then click the relevant port. In the Host Groups tab, click Create Host Groups.
From the Actions menu, select Ports / Host Groups, Fibre, then Create Host Groups.
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.
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.
Select a host mode from the Host Mode list. When selecting a host mode, you must consider the platform and some other factors.
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:
Click Add New Host under the Available Hosts list.
The Add New Host dialog box opens.
Enter the desired WWN in the HBA WWN box.
If necessary, enter a nickname for the host bus adapter in the Host Name box.
Click OK to close the Add New Host dialog box.
Select the desired host bus adapter from the Available Hosts list.
Select the port to which you want to add the host group. For details about host modes, see Host modes.
If you select multiple ports, you may add the same host group to multiple ports by one operation.
If necessary, click Option and select host mode options. For details about host mode options, see Host mode options.
When you click Option, the dialog box expands to display the list of host mode options. The Mode No. column indicates option numbers. Select an option you want to specify and click Enable.
Click Add to add the host group.
By repeating steps from 2 to 8, you can create multiple host groups.
If you select a row and click Detail, the Host Group Properties window appears. If you select a row and click Remove, the message appears asking whether you want to remove the selected row or rows. If you want to remove the row, click OK.
Click Finish to display the Confirm window.
To continue to add LUN paths, click Next.
Confirm the settings and enter the task name in the Task Name box.
A task name can consist of up to 32 ASCII characters (letters, numerals, and symbols). Task names are case-sensitive. (date) - (task name) is input by default.
If you select a row and click Detail, the Host Group Properties window appears.
Click Apply in the Confirm window.
If the Go to tasks window for status check box is selected, the Tasks window appears.
