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.
Enabling LUN security on a port
One of following roles is required to perform this task:
• Storage Administrator (System Resource Management) role
• Storage Administrator (Provisioning) role
To protect mission-critical data in your storage system from illegal access, secure the logical volumes
in the storage system. Use LUN Manager to secure LUs from illegal access by enabling LUN security
on ports.
By default, LUN security is disabled on each port. When registering hosts in multiple host groups,
you must enable LUN security (set the switch to enabled). When you change LUN security from
disabled to enabled, you must specify the WWN of the host bus adapter.
CAUTION: It is best to enable LUN security on each port when configuring your storage system.
Although you can enable LUN security on a port when host I/O is in progress, I/O is rejected with
a security guard after enabling.
