Using Continuous Access Xp Or Continuous Access Xp Journal With Remote Command Devices - HP StorageWorks XP12000 User Manual

NOTE:
Command devices that can be mapped as remote command devices are displayed on External Storage
XP's panes as shown in
When you select Discovery in the Device tree on the LU Operation pane, the external array's WWNs
appear. When you select an external array's WWN in the Device tree, information such as OPEN-V-CM
appears in the Device column of the Device list for command devices that can be mapped. Select a command
device that can be mapped, and follow the procedure in
Using Continuous Access XP or Continuous Access XP Journal
with remote command devices
To use Continuous Access XP or Continuous Access XP Journal with a remote command device, you
would traditionally need two different kinds of ports: an initiator port for Continuous Access XP or
Continuous Access XP Journal, and an external port for the remote command device. However, if you
set the Initiator/External MIX mode, you can use a port as both the initiator port for Continuous Access
XP or Continuous Access XP Journal and as the external port only for remote command device use.
Before setting the Initiator/External MIX mode, you must prepare initiator and external ports in one
port block of Standard mode. You can set the Initiator/External MIX mode on the port block consisting
of the initiator and external ports.
Figure 67 shows the difference between Standard and Initiator/External MIX modes. When ports are
set to Standard modes, you must connect the cables for the initiator and external ports. However, if
you set the Initiator/External MIX mode, you must connect only one cable, and you can use that path
to operate Continuous Access XP or Continuous Access XP Journal and the remote command device.
For more information about port blocks and setting the Initiator/External MIX mode, see the
HP StorageWorks LUN Configuration and Security Manager XP user guide for the
XP12000/XP10000/SVS200.
