External Storage XP user guide 119
connect one cable to one of the ports set to Initiator/External MIX mode, which means that you do not
need to connect cables to each port of different port attributes.
Figure 67 Using Continuous Access XP or Continuous Access XP Journal with remote command devices
Using Initiator/External MIX mode
This section describes the procedure to use Initiator/External MIX mode and the procedure to stop using
Initiator/External MIX mode.
To use Initiator/External MIX mode:
1. Prepare the initiator ports of the Standard mode and external ports of the Standard mode in one port
block.
For the procedure to set the port attribute to initiator, see the HP StorageWorks Continuous Access XP
user guide for the XP12000/XP10000/SVS200 or the HP StorageWorks Continuous Access XP
Journal user guide.
For the procedure to set the port attribute to external, see ”Setting a local array’s port attributes” on
page 72.
2. Set the Initiator/External MIX mode to the port block consisting of the initiator ports of the Standard
mode and external ports of the Standard mode.
For the procedure to set the Initiator/External MIX mode, see the HP StorageWorks LUN Configuration
and Security Manager XP user guide for the XP12000/XP1000/SVS200.
3. Connect the cable to the port, and connect an array to be used as an MCU and local array and an
array to be used as an RCU and external array.
4. Map the command device as the remote command device.
NOTE: Only the command device can be recognized when the discovery operation is performed
using the external port of the Initiator/External MIX mode.
5. Start the Continuous Access XP or Continuous Access XP Journal operation and the remote command
device operation using the port of the Initiator/External MIX mode.
To stop using Initiator/External MIX mode:
1. Stop the Continuous Access XP and Continuous Access XP Journal copy processing and operation.
