HP XP P9000 Continuous Access Synchronous for Mainframe Systems User Guide

5 Configuration
This chapter provides instructions for configuring Cnt Ac-S Z.
Configuration workflow
Configuration consists of the following tasks:
• Check prerequisites for each procedure.
• See “Planning pairs and pair volumes” (page 33).
• On the main and remote system, install the data paths. See “Data path requirements and
configurations” (page 46).
• On main and remote system, configure the initiator and RCU target Fibre Channel ports that
will be used for Cnt Ac-S Z operations. See “Ports” (page 49) and “Defining port attributes”
(page 57) for details.
• On the main system, create the Cnt Ac-S Z association with the remote system. See “Configuring
storage systems, defining logical paths” (page 58). Logical paths between the systems are
added during this procedure.
You may also perform these additional procedures prior to the initial copy:
• Add additional logical paths. See “Configuring additional logical paths” (page 62).
• Specify the number of volumes to copy at one time. See “Setting number of VOLs. copied
concurrently, other options” (page 63).
Defining port attributes
Initiator and RCU target ports must be set up on the main and remote system for Cnt Ac-S Z command
and data transfer.
Prerequisite information
Before configuring ports, make sure they are ready to have a new attribute assigned, as follows:
• If you are changing a target port to an initiator port, prepare the port for the change as follows:
Confirm that the port is offline.◦
◦ Disconnect the port from the host.
◦ Remove all channel paths to the port.
• If you are changing an initiator port to target or RCU target port, prepare the port for the
change as follows:
◦ Release all pairs using the ports.
◦ Delete the paths from the initiator port to the remote storage system.
◦ Delete the RCU.
The number of hosts connected to a target port must be limited to 128 or fewer to avoid
disconnection. See “Ports” (page 49) for information about target, initiator, and RCU target ports.
Procedure 5 To define port attributes:
1. In Remote Web Console, click Actions > Remote Copy > Continuous Access Synchronous for
Mainframe > RCU Operation.
2. Change to Modify mode by clicking the icon.
