HP Storage Essentials Storage Resource Management Report Optimizer Software 6.0 Contexts Guide (October 2008)

Creating Reports in a Complex Environment8
• Use the “Class name” class for a report containing only objects from one class or sub-classes, or
when using Generic and Managed contexts
• Use “Class name for Dependency” when combining objects of different classes. Use “Class
name for Dependency” classes only to find objects used in connectivity or dependency with
objects in other classes. Examples include: host-dependent storage systems and host-dependent
switches.
The following table shows when to use various classes versus their corresponding “XYZ for
Dependency” classes (where XYZ can be Host Volume Capacity Statistics, Storage System Capacity
Statistics, Switch Configuration Statistics, Storage Pool Capacity Statistics, etc.):
Table 1-5: When to Use the “XYZ for Dependency” Classes
Classes Usage Guidelines
• Host Volumes
• Host Volumes for
Dependency
• Host Volume
Management
• Use the Host Volumes class only with the Host class
and/or its sub-classes, or with Generic and Managed
contexts.
• Use the Host Volumes for Dependency class with other
classes, such as Switch, Storage System, or NAS.
• Use the Host Volume Management class when you want
to find volume management volumes information.
• HBA
• HBA for Dependency
• Use the HBA class only with the Host class and/or its
sub-classes. The HBA class provides information about all
of the HBAs for a given host.
• Use the HBA for Dependency class with other classes and
sub-classes, such as Switch, Storage System, or NAS. The
HBA for Dependency class provides information about
HBA connectivity with other devices, but not for all HBAs
on a given host.
• HBA Ports
• HBA Ports for
Dependency
• Use the HBA Ports class only with the Host class and/or its
sub-classes. The HBA Ports class provide information about
all of the HBA ports for a given host.
• Use the HBA Ports for Dependency class with other classes
and sub-classes, such as Switch, Storage System, or NAS.
Use this class to get information about HBA port
dependency or connectivity with other devices. This class
does not provide all of the HBA ports for a given host.
