Defining LU paths
To configure a Fibre Channel or iSCSI environment, complete the following major steps:
1. Find the WWNs of the host bus adapters connected to the Fibre Channel ports (Fibre Channel only).
2. Create host groups (”Creating host groups” on page 30).
3. Register hosts in host groups (”Registering hosts in host groups” on page 31).
4. Associate host groups to logical volumes (”Associating host groups to logical volumes” on page 34).
Creating host groups
You can connect multiple server hosts of different platforms to one port of your disk array. When
configuring the system, you must group server hosts connected to the disk array by host groups. For
example, if HP-UX and Windows hosts are connected to a port, create a host group for each host type.
1. In the LU Path tree, locate the port and verify that LUN security is enabled.
NOTE: If the port icon has a key ( ), LUN security is enabled.
If LUN security is not enabled, right-click the port and select LUN Security: OFF->ON in the shortcut
menu.
2. After LUN security is enabled, right-click the port in the LU Path tree and select Add New Host Group.
The Add New Host Group dialog box appears.

3. In the Group Name box, enter the host group name.
