Adding storage agents to the KSYS

Edit online

In the VM Recovery Manager DR solution, data is replicated from the active site to the backup site by using storage replication. The KSYS manages the storage subsystems for data mirroring as a part of the disaster recovery operations. To manage the storage subsystems, the KSYS uses the APIs that are provided by the storage subsystem. You must register the various storage devices in all sites with the KSYS as storage agents so that KSYS can monitor and manage the data replication across sites. The storage agents interact with the storage devices or the storage controller software in each site depending on the type of storage in your environment.

Note: All the prerequisite software must be installed on the same logical partition in which the KSYS software is installed. If the storage subsystem uses a storage controller software, the storage controller software must also be installed on the KSYS LPAR. The storage controller is the software component that you receive from the storage vendor that allows KSYS to contact storage devices and perform replication operations. For example, identify mirroring pairs, create disk groups, and reverse mirroring.
The VM Recovery Manager DR solution supports the following storage agents:
  • EMC SRDF storage systems
  • SVC and Storwize devices
  • DS8000 series storage devices
  • Hitachi storage devices
  • IBM XIV storage systems
