Procedure to Use Initiator/External MIX Mode

This section describes the procedure to use the Initiator/External MIX mode and the procedure to stop using the Initiator/External MIX mode.

To use the 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 XP24000/XP20000 Continuous Access Software User's Guide or the HP StorageWorks XP24000/XP20000 Continuous Access Journal Software User Guide.

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 XP24000/XP20000 LUN Manager User Guide.

3.Connect the cable to the port, and connect a storage system to be used as an MCU and local storage system and a storage system to be used as an RCU and external storage system.
