Figure 3 Disabling LUN Security

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 Figure 1 on page 16).

Note

: 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” on page 80.

Conﬁguring LUs for Use by RAID Manager

System administrators can enter RAID Manager commands from open-system hosts to perform Continuous

Access and HP StorageWorks XP Business Copy Software operations on logical devices. For example,

adminis

trators 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 entered from open-system hosts. When

the administrator enters an RAID Manager command from an open-system host, the RAID Manager

command is transferred via the command device to the target logical device.

To protect a logical device from RAID Manager commands, you must apply command device security

to the logical device. If command device security is applied to a logical device, the device will not be

affected by RAID Manager commands even when commands are transferred via a command device to

that device.

For d

etails, see “Conﬁguring the Storage System for Using RAID Manager” on page 81.

Note

You cannot use the following volumes as command devices:

• Volumes that do not have Read/Write access attribute

• Volumes reserved by Auto LUN

• Cont

inuous Access volumes

• Business Copy volumes

• Virtual volumes
