HP XP P9500 Storage - Manual (Page 146)

Disabling LUN security
Typically, you do not need to disable LUN security on ports. For example, if LUN security is disabled
on a port, the connected hosts can access only the LUs associated with host group 0, and cannot
access LUs associated with any other host group.
Host group 0 is the only host group reserved, by default, for each port. If you use the LUN Manager
window to view a list of host groups in a port, host group 0, indicated by 00, usually appears at
the top of the list.
The default name of host group 0 consists of the port name, a hyphen, and the number 00. For
example, the default name of host group 0 for port 1A is 1A-G00. However, you can change the
default name of the host group 0.
LUN security is disabled, by default, on each port. When you configure your storage system, you
must enable LUN security on each port to which hosts are connected.
