5 Configuration operations

This chapter provides instructions and information for setting up a Continuous Access Synchronous
Z system that is ready for pair operations.

Configuration workflow

Configuration tasks consist of the following:
Check prerequisites for each procedure.
In the production system, identify the production volume or volumes that will become Continuous
Access Synchronous Z M-VOLs. In the remote backup system, create the volumes that will
become the R-VOLs. For information on pair volume requirements, see
(page 29).
On the main and remote system, install the data paths. For more information, see
data paths" (page
On main and remote system, configure the Fibre Channel ports that will be used for Continuous
Access Synchronous Z operations. Configure initiator and RCU target ports. Review
ports" (page
On the main system, create the Continuous Access Synchronous Z association with the remote
system where your R-VOL(s) will be located. See
paths" (page
You may also perform these additional procedures prior to the initial copy:
Add additional logical paths. See
Specify the number of volumes to copy at one time. See
concurrently, path watch time" (page

Define port attributes

Initiator and RCU target ports must be set up on the main and remote system for Continuous Access
Synchronous 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:
◦ Disconnect the port from the host.
Release affected pairs.
◦
Delete all logical paths.
◦
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 affected pairs.
◦
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.
