Edit online

IBM® VM Recovery Manager DR for Power Systems Version 1.9.0 is the major release of the IBM VM Recovery Manager DR for Power Systems.

New functions for VM Recovery Manager DR for Power Systems Version 1.9.0

VM Recovery Manager DR for Power Systems Version 1.9.0 has the following new functions and updates:
  • Workgroup support in HADRHA mode - You can now group VMs into workgroups for HADRHA configurations, enabling coordinated failover across multiple partitions. For more information, click ../base/ksysmgr.html#ksysmgr__example_mjx_2wp_tfc.
  • Workgroup creation at backup site in shared‑mode environment for DR cluster type - Enable independent setup of workgroups directly on VMs at the DR site. You must create a host group before creating a workgroup on the backup site. This helps manage the VMs present on the backup site without moving the host group to the backup site. For more information, click Workgroup creation at backup site in shared‑mode environment.
  • HADRHA shared mode with Workgroup - Support for workgroup creation in HADRHA shared mode is now available. Workgroups can be created on host groups at the home site to help organize VMs for streamlined disaster recovery operations. For more information, click HADRHA shared mode with Workgroup.
  • HADRHA shared mode- Streamlined shared‑mode replication with automatic host‑pair detection and pre‑deployment checks. For more information, click Creating sites.

New functions for the VM Recovery Manager DR GUI

The VM Recovery Manager DR GUI has the following enhancements:
  • Add  WorkGroup dashboard - Simplifies workgroup creation by combining name, replication policy, and VM selection into one step. For more information, see  WorkGroup  dashboard.
  • Add  Host Group dashboard - Consolidates host group setup name, pairing type, replication policy, and WorkGroup support into a single, guided interface. For more information, see  Add Host Group.
  • HADRHA Host Group Creation - Introduces a unified six‑step flow with consistent UI labels and validations for faster HADRHA deployments. For more information, see  HADRHA Host Group Creation Steps.
  • New system tunable attributes - Two new tunables give you fine‑grained control over KSYS behavior adjust timeouts and retry policies directly in the GUI. For more information, see  Modifying system tunable attributes.
  • Policy‑based replication - Enables policy‑driven replication on SVC storage by selecting Policybased as the replication type at the home site. For more information, see  Policy‑based replication.
