Setting up the environment for HyperSwap

You must set up an environment in which you can run HyperSwap® processing before you can enable HyperSwap for a Copy Services Manager session.

Before you begin

To enable HyperSwap processing on IBM z/OS® systems, the following conditions must exist:

The HSIB and IOSHSAPI address spaces are started on the z/OS system to which the storage systems are connected.
All reserve volumes are converted to global enqueues (ENQs).
The storage system volumes are count key data (CKD) volumes that are attached to a z/OS system. The volumes can be attached to the same z/OS system or different systems.
If the storage system volumes are not connected to a z/OS system on which Copy Services Manager is installed, the required Resource Access Control Facility (RACF®) settings are set on the z/OS system and the SOCKPORT parameter is defined for the HyperSwap management address space IOSHMCTL. This set up enables Copy Services Manager to connect to the z/OS system by using an IP connection. For the required RACF settings, see the IBM® Copy Services Manager Installation and Configuration Guide.

To enable HyperSwap processing on FlashSystem/IBM Spectrum Accelerate systems, the following conditions must exist:

When adding copy sets to a FlashSystem/IBM Spectrum Accelerate session that will support HyperSwap, the source and target volumes in the copy set MUST have the same name. FlashSystem/IBM Spectrum Accelerate requires that the source and target have the same name.
Before a FlashSystem/IBM Spectrum Accelerate session can be enabled for HyperSwap, a Quorum Witness must be defined on the storage system. See the following Redbooks publication (http://www.redbooks.ibm.com/abstracts/redp5434.html) for more information. Also see the Quorum Witness section in the IBM online documentation at https://www.ibm.com/support/knowledgecenter/en/STJKMM_12.3.2/cli_12.3.2.x/r_command__mirroring__quorum_witness_define.html.

Complete the following tasks to set up an environment in which you can run HyperSwap processing on z/OS or FlashSystem/IBM Spectrum Accelerate:

Add a host connection for each z/OS system in the Copy Services Manager GUI. To add a connection, open the Host Connections page and click Add Host Connection.

Note: If the z/OS system is the system on which Copy Services Manager is installed, a native connection is automatically added in the GUI. If the z/OS system does not have Copy Services Manager installed, you must you use an IP connection to connect to the z/OS system.
Add a connection to the storage systems that are attached to the z/OS or FlashSystem/IBM Spectrum Accelerate systems. To add a connection, open the Storage Systems page and click Add Storage Connection. You can connect to a storage system by using a Hardware Management Console (HMC), direct, or a z/OS connection.
Create a session that enables HyperSwap. To create a session, open the Sessions page and click Create Session.
