About Initiators and metro node ports
Metro node ports
The virtual volumes that are created on a device are not visible to hosts until you export them. Virtual volumes are exported to
a host through front-end ports on the metro node directors and HBA ports on the host/server. For failover purposes, two or
more front-end ports can be used to export the same volumes. Typically, a storage view has two ports assigned to it from two
different metro node directors to provide maximum redundancy. When volumes are added to a view, they are exported on all
metro node ports in the view using the same LUN numbers.
Initiators
For an initiator to see the virtual volumes in a storage view, it must be registered and included in the storage views registered
initiator list. The initiator must also be able to communicate with the front-end ports over Fibre Channel connectionseither
through a direct connection or through a fabric.
A volume is exported to an initiator as a LUN on one or more front-end port WWNs. Typically, initiators are grouped so that all
initiators in a group share the same view of the exported storage (they can see the same volumes by the same LUN numbers on
the same WWNs).
Using the Ports view
The Ports view lists all metro node front-end ports used in a cluster. By default, ports are sorted by name, in ascending order.
The arrow in the default sort column indicates the direction of the sort; ascending (
) or descending (
). You can sort columns of data, select one or more objects in the list, and show or hide on the screen.
This screen also shows the following information about ports.
