HP Storage Provisioning Manager (SPM) Version 2.0 User Guide

Table Of Contents
Requirements are matched against a service or service resources. The requirement is said to match
or be satisfied if the service conforms to the requirement.
Service requirements are of two types:
Scalar requirements – requirements which describe a single property, behavior, or policy
Requirement Groups – requirements which group or contain a set of other requirements
All Of requirement
The All Of requirement is a Requirements Group containing other requirements. It specifies that
all of the requirements contained within must be satisfied in order for the All Of requirement to
be satisfied.
NOTE: Top-level service requirements are implicitly contained in an All Of requirement group.
Any Of requirement
The Any Of requirement is a Requirements Group containing other requirements. It specifies that
at least one of the requirements within this requirements group must be satisfied in order for the
requirement to be satisfied. The sub-requirements allowed within an Any Of requirements group
are the requirements allowed within the enclosing requirements group in which the Any Of
requirement is placed.
Connected To Fibre Channel Endpoint requirement
The Connected To Fibre Channel Endpoint requirement is used to require that matching
services must be accessible via the Network which contains the given WWN. The service need
not have an interface exposed on the network, but must allow an interface to the network at
sometime in the future. Use Host requirements to create an interface to the service on the network.
Connected To Network requirement
The Connected To Network requirement is used to require that matching services can be
accessible via the specified Network. The service need not have an interface exposed on the
network, but it must be able to have an interface on the network if desired. Use Host requirements
to create an interface to the service on the network.
Fibre Channel Initiator Endpoint requirement
Fibre Channel Initiator Endpoint is a Requirements Group containing requirements
describing a single Fibre Channel initiator endpoint of a host that is to access the storage service.
The Fibre Channel Initiator Endpoint sub-requirements are described below:
Fibre Channel Endpoint WWN — Interface WWN
Fibre Channel Network — Network to which the initiator WWN is or will be logged
into.
Fibre Channel Proxy Endpoint WWN SAN on which proxy WWN exists is the SAN
to which the interface WWN is connected.
For more detailed information, see Working with Brocade Fibre Channel networks and Working
with unmanaged networks.
The Fibre Channel Initiator Endpoint requirement group must contain a Fibre
Channel Endpoint WWN requirement and optionally can contain one of the other two
requirements to complete the endpoint specification.
