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 P9500/XP7 disk
arrays,
their MP utilization metrics are not applicable for the P9500/XP7 disk arrays. For

The number of components associated with a component type is displayed beside it. For example:
•
DKA (1)
•
RG(s) (12)
In
the above image, under Back-end for the P9500 disk array 53036:

1–1 to 1–12 are the individual RAID groups. The list under 1–1 displays the following
component types:
◦
Physical LDEVs. The number (1) 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 (1) 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
