NOTE:

For the “Volume Creation and LUN Security” option in Path Provisioning, the All Ports node

is not shown because volumes cannot be placed inside HSGs for All Ports.

Each storage system treats host security groups differently. See the following sections for more

information.

EMC CLARiiON and Sun 6130 Storage Systems
Upon the creation of volumes, by default the volume is assigned to one of the two controllers. Even

though this volume is mapped to a controller, it is not visible from the outside world by a host. The

management server reports this volume as unmapped since it is not visible by a host initiator.

Volumes can be only on SPA or SPB because CLARiiON is active/passive storage, which means

it can have only one active path to a volume. Addition of initiators to any of the ports on a

storage processor is listed for all ports of that storage processor.

The HSG is created on all ports of the processor you select unless you select an initiator that uses

a different processor and the initiator does not belong to a host security group. For example,

assume you select processor SPA. Then, you select an initiator that belongs to SPB but it does not

belong to a host security group. The host security group is created for all ports on SPB.

HSGs can consist of initiators (WWN) only. You do not need to specify volumes. The initiator is

shown in both host security groups SPA and SPB.

HSGs can consist of volumes (LUNs) only. You do not need to specify initiators.

When you select an initiator for the host security group, the initiator has to be registered with the

CLARiiON storage system.

You can have more than one initiator in a security group if you have the proper multipathing

software installed on that particular host where the initiator is located.

When you create the HSG by using the management server, the HSG appears as a host with its

volumes and ports displayed underneath the tree in SANtricity.

When you create the HSG by using the management server, you can specify the controller, but

not the port for the HSG.

An initiator is equivalent to a host port in SANtricity.
