# Add ports to port groups

Port groups contain director and port identification and belong to a masking view. Ports can be added to and removed from the port group. Port groups that are no longer associated with a masking view can be deleted.

## Prerequisites

Note the following recommendations:

Port groups should contain four or more ports.

Each port in a port group should be on a different director.

A port can belong to more than one port group. However, for storage systems running HYPERMAX OS 5977 or PowerMaxOS 5978, you cannot mix different types of ports (Fibre or iSCSI ports) within a single port group.

## About this task

Adding ports to port groups:

## Steps

1. Select the storage system.
2. Select Hosts > Port Groups .
3. Select the port group and click .
4. Click the number in the Ports field.
5. Click Add Ports.
   For storage systems running HYPERMAX OS 5977 or PowerMaxOS 5978, if the port group already contains one or more ports of a particular type, the dialog is populated with all available ports of that type. If there are no ports in the port group, you can filter the port list by iSCSI or Fibre.
6. Select the available ports from the list, and click OK to add them to the port group.

   The following properties display:

   Dir:Port—Storage system director and port in the port group.

   Identifier—IQN of an iSCSI endpoint or WWN of an FC port.

   Ports Groups—Number of port groups where the port is a member.

   Masking Views—Number of associated masking views.

   Mapped Volumes—Number of associated mapped volumes.

7. Click OK.
