55 allowed initiators in host security groups – HP Storage Essentials NAS Manager Software User Manual
Page 407
Storage Essentials 5.1 User Guide 375
The number of initiators allowed in the HSG depends on the type of storage system:
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.
