HP StorageWorks XP10000 Disk Array - Manual (Page 25)

If LUN security is enabled, host groups affect which host can access which LUs. Hosts can only access LUs
associated with the host group the hosts belong to. 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.
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.
