8 Setting up storage systems

You can use Replication Manager to replicate volumes or change copy pair definitions. It is necessary
to configure prerequisite settings before replicating volumes. You can specify the prerequisite settings
centrally from Replication Manager, for many storage systems across multiple sites.

This chapter describes the tasks for preparing the replication environment and setting up storage
systems.

About setting up storage systems

For open systems, you can configure the following settings for any number of managed storage
systems. This means that from Replication Manager you can configure the settings centrally, without
having to configure settings separately for each storage system across multiple sites.

You can use Replication Manager to specify the following items for open volumes:

Command devices
If you want to set up copy pairs or change the copy pair status from Replication Manager, you
need to use P9000 RAID Manager. You must first set a storage system volume as a command
device.

Remote paths
If you are using volume replication functionality such as Continuous Access Synchronous or Con-
tinuous Access Journal to perform remote copying (replication of volumes between storage systems),
you must first set up a logical path (remote path) to link the storage systems.

Pools
When Snapshot is used to replicate volumes, a pool that stores differential data for the primary
volume is required to create snapshot images (virtual volumes). Define this pool by setting any
available storage system volume as a pool volume beforehand.

Journal groups
When Continuous Access Journal is used to replicate volumes, journal volumes are required as
buffers for copying volumes. The journal volumes on the primary side are used after being grouped
with the primary volume, and the journal volumes on the secondary side are used after being
grouped with the secondary volume. Therefore, define this journal group in advance by setting
any available storage system volumes as journal volumes.

For mainframe systems, depending on the copy types to be configured some of the storage system
setup operations need to be performed with Remote Web Console. For details on operations to be
performed on Remote Web Console, see the HP StorageWorks P9000 Replication Manager Software
Configuration Guide
.

For a list of available storage system setup functions and required user permissions (Replication
Manager management), see “
