Setting up a global-active device environment After the HCS management server has discovered resources, you can use the
Set up Global-Active Device window for setup tasks that must be performed before global-active device pairs can be allocated.
About global-active device setup The global-active device setup window provides a workflow for configuringrequired storage system resources before global-active device paired
volumes can be allocated.
Access to the global-active device setup window is provided from:
• The Actions menu on the global task bar
• The Replication tab, from General Tasks
The setup window provides access to various HCS or Replication Manager
dialog boxes. As tasks are completed, or if tasks have already been completed by other procedures, the setup window identifies completed tasks
and provides a link to configuration details. If you close the setup window
and reopen it later, the completed tasks remain identified.

							The following figure depicts the setup window configuration items in theglobal-active device environment:
• Select Storage Systems (see 
 below, this task must be done first)
Note:  When global-active device pairs are allocated, the primary storage
system contains the P-VOLs and the secondary storage system contains the S-VOLs.
The following setup tasks can be performed in any order, but must be
completed before allocating global-active device pairs.
• Configure Remote Paths (see 
)
• Configure Quorum Disks (see 
)
• Configure Pair Management Servers (see 
)
• Configure Virtual Storage Machines (see 
)

Prerequisites for global-active device setup  on page 284
Prerequisites for global-active device setup Before performing global-active device setup tasks, ensure the followingprerequisites are met:
• The Virtual Storage Platform G1000 microcode version for both the primary and secondary storage systems must be  80-02-01-XX/XX or later
284Replicating volumes for continuous accessHitachi Command Suite User Guide 
						

							to create global-active device pairs where the P-VOLs already have a
virtual LDEV ID assigned and are managed by user-defined virtual storage machines, as with nondisruptive migration. This requirement is notnecessary for global-active device pairs created by adding secondary
storage resources to the primary storage default virtual storage machine.
• Global-active device has been licensed (which includes Replication Manager).
• Replication Manager is installed and linked to HCS.
• A pair management server is installed with Device Manager Agent and Command Control Interface (CCI) at the primary and secondary storage
sites.
• The external port of the primary and secondary storage systems are connected to the quorum storage system by Fibre Channel or FibreChannel over Ethernet.
• You have registered (discovered) the primary, secondary, and quorum storage systems.
