5. Record the WWN and repeat the above steps for each fibre channel device that you want
to use.
The following is an example of finding a WWN on HP-UX.

Creating a host group and registering hosts in the host group
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 P9500 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.
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 ON, 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.
The following rules apply to nicknames for host group names:
•
A nickname can consist of up to 32 ASCII characters (letters, numerals, and symbols). However,
you cannot use the following characters for nicknames: \ / : , ; * ? " < > |
•
You cannot use space characters for the first and the last characters in nicknames.
•
Nicknames are case-sensitive. For example, wnt and Wnt represent different host groups.
