LUN security on ports

To protect mission-critical data in your storage system from illegal access, apply security policies
to logical volumes. Use LUN Manager to enable LUN security on ports to safeguard LUs from illegal
access.

NOTE:

If a port has the External attribute, you cannot apply LUN security to the port.

If LUN security is enabled on ports, host groups affect which host can access which LUs. Hosts can
access only the LUs associated with the host group to which the hosts belong. Hosts cannot access
LUs associated with other host groups. For example, hosts in the hp-ux host group cannot access
LUs associated with the windows host group. Also, hosts in the windows host group cannot access
LUs associated with the hp-ux host group.

Examples of enabling and disabling LUN security on ports

Enabling LUN security

In the following example, LUN security is enabled on port CL1-A. The two hosts in the hg-lnx
host group can access only three LUs (00:00:00, 00:00:01, and 00:00:02). The two hosts in the
hg-hpux

host group can access only two LUs (00:02:01 and 00:02:02). The two hosts in the

hg-solar

host group can access only two LUs (00:01:05 and 00:01:06).
