HP Storage Provisioning Manager (SPM) version 2.3 User Guide

5 Storage service provisioning
Storage services represent a set of requirements and, when activated, a set of storage resources
that meet those requirements. There are three types of storage services: Volume Service, SAN
Connected Volume Service, and SAN Connectivity Service. For more information on service types,
see:
• SAN connected volume service
• Volume service
• SAN connectivity service
NOTE: Matrix OE uses only the SAN connected volume service type.
Services can be created in the SPM GUI using the Service Provisioning Wizard or through Matrix
OE. Before activation, a service is in the unresourced state. An unresourced service has requirements
but no associated resources. Successfully activating a service moves it to the resourced state. A
resourced service can be deactivated to release the associated resources, or it can be reactivated
(activated again while in the resourced state) to automate changes necessary to meet new or
modified requirements. While reactivation of a service can cause automation to occur, the
automation does not change the data that is presented to the user. For example, reactivating a
volume service does not change which volume the service is associated with, but it may make the
volume grow or change its presentation, depending on the requirements. See Figure 3.
Figure 3 SPM service lifecycle
A service in the resourced state is conformant if and only if the resources associated with the service
meet the service requirements. San Connected Volume services are hierarchically composed of
other services. In general, a service composed of other services is conformant when its child services
are conformant. However, there may be implicit requirements of parent services that may not be
met even if all child services are conformant.
