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 ” on page 39.
To create a host group:
1. Start LUN Manager and display the LUN Manager window ( Figure 4 on page 21).
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 ( Figure 19 on page 38) 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.
4. Select a host mode from the Host Mode drop-down list. When selecting a host mode, you must
consider the platform and some other factors (see Table 2 on page 38 for details).
Caution : Do not select Reserve from the drop-down list. Reserve indicates that the host mode
is not currently supported.
5. If necessary, click the Option button and then select host mode options (see Figure 19 on page 38).
For detailed information about host mode options, see Table 3 on page 39.
6. Click OK to close the Add New Host Group dialog box. If a message appears, click OK.
The host group name and the host mode are displayed in blue.
7. Click the Apply button in the LUN Manager window.
A message appears and asks if you want to apply the setting to the storage system.
8. Click the OK button to close the message.
