HP P6000 Cluster Extension Software Administrator Guide (5697-2274, November 2012)

HP Storage Management Initiative Specification
To control P6000 Continuous Access-mirrored vdisks from a server, P6000 Cluster Extension uses
the HP SMI-S interface. The HP SMI-S client implemented in the P6000 Cluster Extension cluster
integration, or in the CLI, communicates with the HP SMI-S server running on the P6000 Command
View management server.
NOTE: In this context, the term management server refers to the server running HP P6000
Command View. The management server could be a general-purpose server, dedicated management
server, ProLiant Storage Server, or SMA.
Consider the following about the HP SMI-S server:
• The HP SMI-S server implements the programmatic interface and functionality of the P6000
Command View and P6000 Continuous Access user interfaces.
• HP SMI-S uses the CIM and WBEM specifications to define common models for storage
hardware and storage functions.
• For P6000 Cluster Extension, a HP SMI-S server is required to control P6000 Continuous
Access operations and to gather storage system status information. The HP SMI-S server names
are stored as objects, and an encrypted configuration file stores access information for each
application service. In addition, you can configure several management servers to provide
additional redundancy, so that P6000 Cluster Extension will switch to the next available
management server when a management server becomes unavailable.
• The HP SMI-S software must be installed on each management server and should be running
at all times to provide failover capability.
