SMI-S profiles

The Storage Management Initiative Specification (SMI-S) was developed by members of the Storage Networking Industry Association (SNIA) and defines an interface for the secure, extensible, and interoperable management of a distributed and heterogeneous storage system. The specification describes the information available to a WBEM client from an SMI-S compliant CIM WBEM server.

The SMI-S specifies standards-based profiles to manage storage networks. It builds on other standards such a CIM. The scope of SMI-S includes storage, storage virtualizers, fibre channel fabrics and IP connectivity, and host storage-specific CIM-based profiles.

The host storage portion of the specification defines profiles for the management of host-based storage devices.

CIM for z/OS supports the host-based storage profiles:

Host Discovered Resources profile

The Host Discovered Resources (HDR) profile defines the model for the storage devices presented to z/OS.

SB Multipath Management profile

The Host Discovered Resource profile defines the model of the logical relationship of a host driver path to a logical unit. The SB Multipath Management profile defines the asynchronous notification of changes applying to this relation, using CIM life cycle indications.

Storage HBA profile

The Storage Host-Bus-Adapter (HBA) profile represents the manageable elements of an HBA and optionally, the storage connected to it, including the HBA Hot Swap Events for HBA creation and deletion, using CIM life cycle indications.
