Setting a name for a user-defined consistency group

Edit online

You can set a name to a user-defined consistency group.

About this task

You can set a name to a user-defined consistency group.

For Metro Mirror session types, adding a name for a user-defined consistency group provides the following advantages:
  • Ability to load multiple sessions under a single HyperSwap configuration for a Sysplex.
  • Ability to suspended multiple role pairs across sessions consistently.

For Global Mirror sessions, adding a user-defined consistency group name enables multiple role pairs across different sessions to share the same Global Mirror Master session ID. With the same Global Mirror master session ID you can manage multiple Global Mirror environments separately, without exceeding the limits on the number of master sessions allowed on the DS8000®.

For multi-target Metro Mirror-Metro Mirror and 4-Site Metro Mirror-Metro Mirror session types, adding a user-defined consistency group name ensures that the configuration name is unique across other sessions. The configuration name is added in the Input/Output Supervisor (IOS) when a HyperSwap or Hardened Freeze configuration is loaded on z/OS.

  1. In the menu bar, click Sessions.
