Figure 2 Enabling LUN Security
Usually, you do not need to disable LUN security on ports. If LUN security is disabled on a port,
the connected hosts will only be able to access LUs associated with host group 0 (zero), and will
be unable to access LUs associated with any other host group.
Figure 3 Disabling LUN Security
The host group 0 is the only host group reserved for each port by default. If you use the LUN
Manager window 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 the number 00 (see
“LU Paths Configuration in a Fibre Channel
Environment” (page 8) ).
By default, the name of host group 0 consists of the port name, a hyphen, and the number 00. For
example, host group 0 for port 1A is named 1A-G00 by default. Note that you can change the
name of host group 0.
By default, LUN security is disabled on each port. When you configure your system, you must
enable LUN security on each port to which hosts are connected.
For details on how to apply LUN security, see “Using LUN Security” (page 83) .
Configuring LUs for Use by RAID Manager
System administrators can enter RAID Manager commands from open-system hosts to perform XP
Continuous Access and HP StorageWorks XP Business Copy Software operations on logical devices.
For example, administrators can enter RAID Manager commands to create or split pairs. To allow
the administrators to use RAID Manager commands, you must ensure that at least one logical
device is used as a command device. A command device receives RAID Manager commands
