Manage and maintain PowerHA copy descriptions

Copy descriptions are used in IBM PowerHA SystemMirror for i to store information used in Geographic Mirror, Metro Mirror, Global Mirror, and FlashCopy copy sessions. The copy descriptions provide an auxiliary storage pool (ASP) session with the information such as specific disk units or access credentials that the session needs to perform its operations.

After adding a copy description, you can:
  • display the description information.
  • change the copy description information.
  • remove the copy description.

Copy descriptions content varies depending on the type of storage your system uses and the type of copy session the description supports.
