Managing replication with IBM Spectrum Virtualize 3-Site Orchestrator
To update a 3-site consistency group, add a relationship to a 3-site consistency group,
or to recover from a link failure or site disaster, use the information in the topics that
follow.
Changing configuration settings in the IBM Spectrum Virtualize 3-Site Orchestrator IBM Spectrum Virtualize 3-Site Orchestrator .Converting a Metro Mirror consistency group to a 3-site consistency group Adding a Metro Mirror relationship to an existing 3-site consistency group If you are using Orchestrator 3.0, you must create empty volumes before you can adding a 2-site Metro Mirror relationship to a 3-site consistency group. Orchestrator 4.0 supports the ability to add a 2-site remote-copy relationship with data to a stopped 3-site consistency group. Adding a Metro Mirror relationship with data to a 3-site consistency group Converting a HyperSwap consistency group to a 3-site consistency group Adding a HyperSwap relationship to an existing 3-site consistency group If you are using Orchestrator 3.0, The HyperSwap relationship must be empty and cannot contain volumes with active data. HyperSwap relationships must be in the consistent synchronized state before they can be added to a 3-site consistency group. Adding a HyperSwap relationship with data to 3-site consistency group Reverting a 3-site consistency group to a 2-site consistency group You can take an existing 3-site consistency group and convert it to a 2-site consistency group for both Metro Mirror or HyperSwap configurations. Removing and reverting relationship from 3-site consistency group Migrating or reinstalling IBM Spectrum Virtualize 3-Site Orchestrator Updating IBM Spectrum Virtualize 3-Site Orchestrator installation package You can upgrade the currently installed version of the IBM Spectrum Virtualize 3-Site Orchestrator to newer version of the 3-Site Orchestrator. Rolling back IBM Spectrum Virtualize 3-Site Orchestrator installation package IBM Spectrum Virtualize 3-Site Orchestrator installation package to an earlier version. For example, if you need to roll back your system software to an earlier version, you can move to an earlier version of the installation package, if necessary.Changing the cycle period cycle period is the minimum time, in seconds, between copy cycles in a 3-site consistency group. Changing the periodic source 3site_consistent, 3site_inconsistent, and stopped states.Changing the primary site stopped state before you change the primary site in a 3-site consistency group. Stopping replication on an auxiliary-far site for maintenance Stopping replication on a HyperSwap topology system or an auxiliary-far site for maintenance Excluding a near site for maintenance If the system at the near site needs maintenance or an update of system software, you must exclude that site from the 3-site consistency group. After you complete the maintenance, you can join the system at that site back into the 3-site configuration. Updating the system software in a Metro Mirror 3-site configuration IBM Spectrum Virtualize software on any of the systems in a 3-site configuration that uses Metro Mirror, you must complete several tasks in IBM Spectrum Virtualize 3-Site Orchestrator before and after you update the software.Updating the system software in a Metro Mirror 3-site configuration with clustered systems Upgrading the system software in a HyperSwap 3-site configuration IBM Spectrum Virtualize software on any of the systems in a 3-site configuration that uses HyperSwap and systems, you must complete several tasks in IBM Spectrum Virtualize 3-Site Orchestrator before and after you update the software.Maintaining the hardware on a HyperSwap 3-site configuration with clustered systems IBM Spectrum Virtualize 3-Site Orchestrator .
