2. Click Add New Port.
If the WWN and nickname are not in the list, the port is added. If the WWN is in
the list, the nickname is changed. If the nickname is in the list, you must specify a
unique nickname.
To delete either a manually added port or the nickname of an automatically added
port:
In the host port's row, click Delete.
If the host scanned for devices since the storage system was restarted, restart the
system to complete the deletion.
The global host list is a list of ports on a host HBA that can be used for volume
mapping.
The list is automatically populated with port WWNs of hosts that have sent an
command or a command to the system. Hosts typically do
this when they boot up or rescan for devices. When the command from the host
occurs, the system saves the host port information; however, the information is not
retained after you restart the system unless you have assigned the port a nickname.
Each list entry specifies the controller ports through which the host is connected, the
host-port manufacturer, and the host-port nickname (if any).
You can manually add ports to the list. You can assign a nickname to a port to make
it easily recognizable. A maximum of 63 nicknames can be assigned.
Before you can manually add a host port to the list you must know the port
WWN.
To display the global host list:
Select Manage > General Config > Manage Host List.
The Current Global Host Port List panel shows the port WWN, controller ID and
port number, manufacturer, and nickname (if any) for each host port. The port
associated with the host that most recently scanned for devices is first in the list.
