Defining A New 4X4X4 Cascade Configuration - HP XP P9500 Software User's Manual

The copy group is registered in the EXCTG of the storage system when the YKMAKE command is
executed. If a copy pair has already been created, executing the YKMAKE SELECT(COND)
command simply registers the copy group in the EXCTG.
This subsection describes the procedures for defining a 4x4x4 Cascade configuration for each of
the following cases:
1.

Defining a new 4x4x4 Cascade configuration

2. Expanding to a 4x4x4 Cascade configuration by adding Continuous Access Journal Z copy
groups to Continuous Access Synchronous Z copy groups
3. Expanding to a 4x4x4 Cascade configuration by adding a series of storage systems to a 3DC

Setting up the Storage System
Set up the following items by using Remote Web Console.
1. Configure an arbitration command device on the subordinate disk controller.
2. Set up an arbitration path from the supervisor disk controller to the subordinate disk controller.
3. Map the arbitration command device on the subordinate disk controller to the supervisor disk
controller (setup of the remote command device).
4. Register the journal group (timer type: SYSTEM) in each of the intermediate site and remote
site storage systems.
Setting up a Business Continuity Manager Environment
Creating a disk configuration definition file
Perform a scan that includes the volumes to be defined in the copy group and the command device.
1. From the primary host, perform a Local Scan on the primary site storage system.
2. From the intermediate host, perform a Local Scan on the intermediate site storage system.
3. From the remote host, perform a Local Scan on the remote site storage system.
