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 your settings centrally, without having to configure them separately
for each storage system across multiple sites.
TIP:
If the Device Manager used to set up the storage system is not on the same management server as
Replication Manager, you must synchronize the configuration information. For details, see About
refreshing configuration information on page 260.
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 a list of available storage system setup functions and required user permissions (Replication
Manager management), see Storage system setup functions on page 104.
