server displays these volumes as unmapped since no external host can see these volumes yet.
• You can have 0 to multiple initiators in a host security group
• You can have 0 to multiple volumes in a host security group.
• Every HSG is only on one port on the array. You can have host security groups with the same
name, as long as they are on different ports.
• Host security groups appear in the native tool for HDS storage systems in the logical view, listed
by LDEV and in the physical view, listed by port.
• In the native tool for HDS storage systems, host security groups are referred to as a host security
