•The management server can read the names of host security groups created by the native tool.

•Creation of a new host security group with an initiator that already exists in another host security group adds the volumes to the previously created host security group.

•The management server displays the ports connected to the initiator you selected for creating an host security group. If the initiator is not connected to any ports, no ports are displayed.

•If you select a number of ports, only the selected initiators will be part of the host security group.

•Only the storage ports connected to the initiator in the host security group will be included in the host security group, even if the default is all ports. For example, if an initiator is not connected to a storage system, no ports will be in the host security group.

Accessing Information About Host Security Groups

Host Security Groups define which initiators (HBA ports) have access to specified storage volumes. They are associated with a Fiber Channel port and contain a list of HBA port initiators and the volumes they can detect.

Keep in mind the following:

•Each type of storage system treats host security groups differently. For more information, see ”General Provisioning Issues” on page 563.

•Not all HDS storage systems support host security groups. Refer to the documentation accompanying the HDS storage system.

If you use another product to make provisioning changes, you must perform Discovery Data Collectionfor the management server to be made aware of these changes.

You can access information about host security groups from Provisioning Manager or from System Manager.

To access host security groups from Provisioning Manager:
