HP XP Performance Advisor Software - Manual (Page 245)

In the above image, under Back-end for the XP disk array 10090:
•
DKA is a component type. The number (2) indicates the number of DKA pairs available on
the selected XP disk array.
◦ AUMU is an individual DKA pair
◦ BUNU is an individual DKA pair
•
RG(s) is a component type. The number (6) indicates the number of RAID groups configured
on the selected XP disk array.
1–1 to 1–6 are individual RAID groups. The list under 1–1 displays the following component
types:
◦ Physical LDEVs. The number (543) indicates the number of LDEVs associated with the
selected RAID group 1–1. Click Physical LDEVs to see the list of physical LDEVs that belong
to the selected RAID group.
◦ Pool LDEVs. The number (25) indicates the number of physical LDEVs assigned to a pool
from RAID group 1–1. Click Pool LDEVs to see the list of physical LDEVs assigned to a
pool. The pool to which the physical LDEVs belong are also displayed beside the LDEV
IDs.
The ThP or the snapshot pool to which the physical LDEVs are assigned can also be traced
under the respective Pools main category or the Snapshot Pool main category, where the
corresponding ThP or snapshot pool IDs are displayed and list the of LDEVs assigned to
these pools. For more information, see
“Pools navigation path” (page 247) and “Snapshot
Pool navigation path” (page 251) .
For the P9000 disk arrays
The Back-end main category comprises of the DKA pairs, RAID groups, and LDEVs, where DKA
and RAID groups are the main component types that further expand to display the associated
components. Following is the component selection path:
•
Back-end > DKA (component type) > Individual DKA pairs.
•
Back-end > RG(s) (component type) > Individual RAID Groups.
Individual RAID Groups > Physical LDEVs (component type) > Individual physical LDEVs ◦
◦ Individual RAID Groups > Pool LDEVs (component type) > Individual LDEVs assigned to
a pool
The pool to which an LDEV belongs is also displayed in brackets beside the LDEV ID. For
example, E:31 (Pool ID:4).
IMPORTANT: Since, the ACP/DKA MPs are moved to the MP blades in the P9000 disk arrays,
their MP utilization metrics are not applicable for the P9000 disk arrays. For more information see
“Viewing MP blade utilization for P9000 disk arrays” (page 190) .
The number of components associated with a component type is displayed beside it. For example:
•
DKA (1)
•
RG(s) (12)
