5 Cnt Ac-S Z configuration
This chapter provides instructions for configuring Continuous Access Synchronous Z.
Configuration workflow
You must have Storage Administrator (Remote Copy) role to perform most Continuous Access
Synchronous Z operations using Remote Web Console.
Configuration consists of the following operations:
•
Check prerequisites for each procedure.
•
See “Planning pairs and pair volumes” (page 34) .
•
On the primary and secondary system, install the data paths. See “Data path requirements
and configurations” (page 46) .
•
On primary and secondary system, configure the initiator and RCU target ports Fibre Channel
ports that will be used for Continuous Access Synchronous Z operations. See
“Ports” (page 49)
and “Defining port attributes” (page 59) for details.
•
On the primary system, create the Continuous Access Synchronous Z association with the
secondary system. See
“Setting up primary and secondary systems for Cnt Ac-S Z” (page 60) .
Remote paths between the systems are added during this procedure.
You may also perform these additional procedures prior to the initial copy:
•
Add additional remote paths. See “Configuring additional remote paths” (page 86) .
•
Specify the number of volumes to copy at one time. See “Setting # of vols. copied, path
blockade, other options” (page 62) .
Defining port attributes
Initiator and RCU target ports must be set up on the primary and secondary system for Continuous
Access Synchronous Z command and data transfer.
Prerequisite information
•
Storage Administrator (System Resource Management) is required.
•
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.
•
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 secondary storage system.
◦ Delete the secondary storage system from the Cnt Ac-S Z relationship. See “Deleting
Continuous Access Synchronous Z” (page 90) .
