Deleting Continuous Access Synchronous Z
You can delete the Continuous Access Synchronous Z relationship between the primary and
secondary systems. This is done by deleting remote connections.
Prerequisite information
•
All Cnt Ac-S Z pairs must be deleted before removing the connection.
•
When the remote connection is deleted, all remote paths are deleted.
•
Deleting the Cnt Ac-S Z relationship with a specific secondary system does not affect Cnt Ac-S
Z operations between other primary systems and the secondary system.
•
After a secondary system is deleted, you can reconfigure the remote path to then connect
another secondary system to the primary system. You can also delete the remote connection
and reconfigure the primary system ports (initiator ports to ordinary target ports for fibre) to
provide additional host channels for the primary system.
Procedure 28 To delete the Continuous Access Synchronous Z relationship
1. In the Storage Systems tree, click Replications > Remote Connections.
2. In the Remote Connections window, click the Connections (To) tab.
3. In the Connections (To) tab, select the remote connection to be deleted.
4. From the Actions menu, click Remote Connections > Remove Remote Connection.
5. In the Remove Remote Connection window, from the Selected Remote Connection table, select
the connection to be removed.
(You can review information about the connection by clicking Detail.)
6. Click Apply.
ICKDSF Considerations for Cnt Ac-S Z Volumes
The XP7 supports the use of the ICKDSF utility program. ICKDSF performs functions for the
installation, use, and maintenance of DASD and service functions, error detection, and media
maintenance. For further information about ICKDSF, see the IBM document, ICKDSF R16 Refresh
User’s Guide (GC35 0033), or other IBM documents on ICKDSF R16 or later. See the Mainframe
