About this task

To enable HyperSwap for a session, complete the following steps:

1. In the Copy Services Manager menu bar, click Sessions.
2. On the Sessions page, select the session.
3. From the Session Actions list, select View/Modify > Properties.
4. In the View/Modify Properties notebook, select the following properties on the applicable role pair options tab:

   For HyperSwap

   System or sysplex

   Select the z/OS® system or sysplex that you want to associate with the session. Commands for z/OS features are issued to this system or sysplex. Volumes in the session must be attached to the system or sysplex to enable the features.

   Manage H1-H2 with HyperSwap

   Select this option to trigger a HyperSwap operation, which redirects application I/O to the target volumes when there is a failure on the host accessible volumes. Copy Services Manager uses HyperSwap to manage the H1-H2 sequence of a Metro Mirror or Metro Global Mirror session.

   Disable HyperSwap

   Select this option to prevent a HyperSwap operation from occurring.

   Reset In Use By System on Secondary Volumes

   Select this option to have the load of the configuration automatically reset the In Use By System state on all secondary volumes (UCBNALOC = OFF). When this option is not selected, a load of the configuration fails when secondary volumes are in the In Use By System state (UCBNALOC is ON). This feature is only available after APAR OA53082 is applied to the z/OS system.

   Unbox Secondary Volumes

   Select this option to have the load of the configuration automatically unbox all secondary volumes in the configuration. When this option is not selected, a load of the configuration fails when secondary volumes are in a boxed state. This feature is only available after APAR OA53082 is applied to the z/OS system.

   On Configuration Error:

   Partition the system(s) out of the sysplex

   Select this option to partition a new system out of the sysplex when an error occurs because the system cannot be added to the HyperSwap configuration.

   Disable HyperSwap

   Select this option to prevent a HyperSwap operation from occurring.

   On Planned HyperSwap Error:

   Partition out the failing system(s) and continue swap processing on the remaining system(s)

   Select this option to partition out the failing system and continue the swap processing on any remaining systems.

   Disable HyperSwap after attempting backout

   Select this option to enable IOS to back out the HyperSwap operation, if possible, if an error occurs during HyperSwap processing. HyperSwap is disabled.

   On Unplanned HyperSwap Error:

   Partition out the failing system(s) and continue swap processing on the remaining system(s)

   Select this option to partition out the failing systems and continue HyperSwap processing on the remaining systems when a new system is added to the sysplex and the HyperSwap operation does not complete.

   Requirement: If you select this option, you must restart the system.

   Disable HyperSwap after attempting backout

   Select this option to enable IOS to back out the HyperSwap operation, if possible, if an error occurs during HyperSwap processing. HyperSwap is disabled.

   For FlashSystem/IBM Spectrum Accelerate HyperSwap

   Manage H1-H2 with HyperSwap

   Select this option to enable the relationship for HyperSwap on FlashSystem/IBM Spectrum Accelerate volumes. This option redirects application I/O to the target volumes when there is a failure on the host accessible volumes.
