HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

Selecting components and metrics
The component selection tree provides a hierarchal representation of components under the following
main nodes:
• The XP and the P9000 disk arrays monitored by P9000 Performance Advisor. Click the + sign for
an individual XP or a P9000 disk array node to view the corresponding main categories in the
component selection tree (see the following table). If an XP or a P9000 disk array supports a
particular component type and it is not configured on that XP or P9000 disk array, the main cat-
egory is still displayed in the component selection tree. However, the associated metrics are not
displayed for selection and the Choose Metrics box is also disabled.
• Custom Groups, that displays the individual custom groups. Click an individual custom group to
view all the associated LDEVs grouped in the LDEV component type. For more information on
creating custom groups, see “Creating custom groups” on page 104. For more information on se-
lecting custom groups, see “Custom groups navigation path” on page 298.
XP or P9000 disk arrays monitored by P9000 Performance Advisor
Each XP or P9000 disk array can be identified by its DKC or model number. If user-friendly name is
provided, it appears in brackets beside the DKC number. The components in an XP or a P9000 disk
array are logically grouped in the following main categories:

For an XP disk array, Front-end comprises of the frontend
components, such as the ports and associated MPs and CHAs. For
more information, see “Front-end navigation path” on page 272.
For a P9000 disk array, Front-end comprises of the frontend
components, such as the ports and the associated CHAs. For more
information, see “Front-end navigation path” on page 272.
Front-end
Comprises of individual CLPRs. For more information, see “Cache
navigation path” on page 275.
Cache
Comprises of individual MP blades and the associated processors.
For more information, see “MP Blades navigation
path” on page 277.
NOTE:
The MP Blades category is applicable only for the P9000 disk
arrays.

For an XP disk array, Back-end comprises of the backend
components, such as the DKA pairs, associated MPs, and the RAID
groups. The RAID groups further comprises of the associated
physical LDEVs and the pool LDEVs (LDEVs assigned to a ThP or a
snapshot pool). For more information, see “Back-end navigation
path” on page 278.
