Finding WWN for AIX, IRIX, or Sequent
To find the WWN in an AIX, SGI Irix, or Sequent environment, use the fibre switch that is connected
to the host. The method of finding the WWN of the connected server on each port using the fibre
switch depends on the type of switch. For instructions on finding the WWN, see the manual of the
corresponding switch.
Creating Host Groups
You can connect multiple server hosts of different platforms to one port of your storage system.
When configuring your system, you must 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, you must
create one host group for HP-UX hosts and also create another host group for Windows hosts.
Next, you must register HP-UX hosts to the corresponding host group and also register Windows
hosts to the other host group.
The following procedure describes how to create a host group. The procedure for registering hosts
to a host group is described in “Registering Hosts in Host Groups” (page 37).
To create a host group:
1. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When
Selecting Icon under Fibre Folder)” (page 13)).
2. Right-click the port for which you want to create a host group. Next, select Add New Host
Group from the pop-up menu.
The Add New Host Group dialog box (“Add New Host Group Dialog Box” (page 34)) appears.
NOTE: If you right-click an initiator port, you will be unable to select Add New Host Group.
You cannot create host groups for initiator ports.
3. Enter the host group name in the Group Name box.
It is convenient if you name each host group after the host platform. For example, if you are
creating a host group to register Windows NT hosts in, the host group name can be wnt.
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.
