24 Overview of LUN Manager

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.

In Figure 5, LUN security is enabled on port CL1-A. The two hosts in the hp-lnx host group can only access

LUs 00:00, 00:01, and 00:02. The two hosts in the hg-hpux host group can only access LUs 02:01 and

02:02. The two hosts in the hg-solar host group can only access LUs 01:05 and 01:06.

Figure 5 Enabling LUN security

Usually, you do not need to disable LUN security on ports. If LUN security is disabled on a port,

connected hosts can only access LUs associated with host group 0, and cannot access LUs associated

with any other host groups.

Figure 6 Disabling LUN security

Host group 0 is the only host group reserved for each port by default. If you use the LUN Manager pane

to view a list of host groups in a port, host group 0 usually appears at the top of the list and is indicated

by 00 (see Figure 2).

NOTE: By default, the name of host group 0 consists of the port name, a hyphen, and 00. For example,

host group 0 for port 1A is named 1A-G00 by default. You can change the name of host group 0.

By default, LUN security is disabled on each port. When you configure the system, you must enable LUN

security on each port to which hosts are connected.
