Overview of Truecopy/HUR Management

Edit online

Hitachi Truecopy/HUR storage management uses Command Control Interface (CCI) operations from the AIX® operating system and PowerHA® SystemMirror® Enterprise Edition environment.

PowerHA SystemMirror Enterprise Edition uses these interfaces to discover and integrate the Hitachi Storage replicated storage into the HADR framework of PowerHA SystemMirror Enterprise Edition. This integration enables you to manage HADR for applications consuming the mirrored storage.

Integration of Truecopy/HUR and PowerHA SystemMirror Enterprise Edition provides the following:
  • Support for Prefer Primary Site or Online on Either Site inter-site management policies.
  • Flexible user-customizable resource group policies.
  • Support for cluster verification and synchronization.
  • Limited support for the PowerHA SystemMirror Enterprise Edition Cluster Single Point Of Control (C-SPOC).
  • Automatic failover and reintegration of server nodes attached to pairs of Truecopy/HUR disk subsystem within sites and across sites.
  • Automatic management for Truecopy/HUR links.
  • Management for switching the direction of the Truecopy/HUR relationships when a site failure occurs. This process allows the backup site to take control of the PowerHA SystemMirror Enterprise Edition managed resource groups from the primary site.
