commands can be used to create and split pairs. To enable the system administrator to enter RAID

Manager commands from open-system hosts, you must specify at least one logical device as the command

device. You can also apply command device security to other logical devices in the storage system.

Notes

: If a storage system is divided into SLPRs, and you want to prevent RAID Manager commands from

affecting multiple SLPRs, you must apply command device security to the logical volumes.

Specifying Logical Devices as Command Devices

To enable the system administrator to execute RAID Manager commands from an open-system host, you

must select at least one logical device that will not be manipulated by Continuous Access or Business

Copy, and then specify the device as the command device. When an RAID Manager command is issued

from a host, the command is received by the command device. The command device transfers the

command to a

nother logical device. Then, the command performs an Continuous Access or Business

Copy operation on that logical device.

To specify a logical device as a command device:

1. Start LUN Manager and display the LUN Manager window (Figure 4 on page 21).

2. In the uppe

r-right LU Path list or the lower-right LDEV list, select and right-click the desired

logical device.

Notes

• If nothing

is displayed in the LU Path list, select a host group

in the tree.

•The icons

and indicate command devices.

•The icon

indicates no logical device.

3. From the pop-up menu, select Command Device: Disable -> Enable.

A message appears, asking if you want to use the logical device as a command device.

4. Click the YES button to close the message.

5. Click the Apply button in the LUN Manager window.

A message appears and asks if you want to apply the setting to the storage system.

6. Click the OK button to close the message.

The settings are applied to the storage system.

Deleting Command Devices

To delete a command device:

1. Start LU

N Manager and display the LUN Manager window (Figure 4 on page 21).

2. In the upper-right LU Path list or the lower-right LDEV list, select and right-click a command

device (

or ).

3. From the pop-up menu, select Command Device: Enable -> Disable.

A message appears.

4. Click the YES button to close the message.

5. Click the Apply button in the LUN Manager window.

A message appears and asks if you want to apply the setting to the storage system.

6. Click the OK button to close the message.

The settings are applied to the storage system.

Enabling Command Device Security

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

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

be affected by RAID Manager commands issued via command devices from the hosts.

To apply command device security to a logical device:

1. Star

t LUN Manager and display the LUN Manager window (Figure 4 on page 21).
