For Windows Clustering, HP 3PAR Cluster Extension is shipped as a resource DLL. For RHEL and
SUSE, HP 3PAR Cluster Extension is shipped as a binary executable that is called by native clustering
software when data replication is enabled through the package control script.
With both Windows and Linux, the installation of HP 3PAR Cluster Extension also includes a CLI
for custom HP 3PAR Remote Copy integration. Customized solutions for failover application services
must implement HP 3PAR Cluster Extension through the CLX CLI (clx3PARrun.exe) prior to the
disk activation procedure on the server.
HP 3PAR Remote Copy
HP 3PAR Remote Copy is a product that allows you to copy virtual volumes from one HP 3PAR
storage system to another. The copy can be used for disaster recovery, backup, or data migration.
NOTE: HP 3PAR Remote Copy requires 3PAR Remote Copy licenses for all storage servers
participating in a Remote Copy replication. See the 3PAR InForm OS Concepts Guide for additional
information on licensing and features.
