Select LUSE to sort LDEV data based on the LUSE
information, which indicates if an LDEV is also an LUSE
(LUN Size Expansion (Luse).E = Master C = Component).

The data displayed in the LDEV table is either black or blue text. The black text indicates that no
additional information is available and the blue text indicates hyperlinks that you can click to view
the respective component information in a separate browser window. Most of the hyperlinks display
performance graphs of components for the associated metrics in the Chart Work Area; all other
hot links display information in different formats.
To query and sort the data:
1.
Select the date and time stamp in the Last Collection section.
2.
Click Query. If you do not select a last collection date and time stamp, the current last collection
date and time stamp is considered for querying the data.
IMPORTANT:
•
For an XP24000 Disk Array, the performance data can be collected on 64000 LDEVs
(64K binary (65,536)).
•
For the XP or the P9000 disk arrays with external LDEVs, – is displayed under ACP PAIR
in the LDEV table, as the external LDEVs do not have a valid ACP pair associated with
them. Hence, all the external LDEVs for an XP or a P9000 disk array are grouped under
–. The P9500, XP24000, XP20000, XP12000, XP10000, and SVS200 Disk Arrays
support external LDEVs.
•
For the XP24000, XP20000, XP12000, XP10000, and SVS200 Disk Arrays, double-click
an SLPR or CLPR value to view the respective details. For more information, see
and
•
For a P9000 disk array such as the P9500 Disk Array, you can directly view the CLPR
details. The SLPR details are displayed only for the XP disk arrays.
•
For snapshot and ThP pools in the XP disk arrays, the SLPR and CLPR details are displayed
only for the associated LDEVs. The SLPR and CLPR details are not displayed for the LDEVs
that form the snapshot and ThP pools.
For snapshot and ThP pools in the P9000 disk arrays, only the CLPR details are displayed
for the associated LDEVs. The CLPR details are not displayed for the LDEVs that form the
snapshot and ThP pools.
•
A ThP or snapshot pool must have at least one VVOL assigned to it, so that the ThP or
snapshot pool is displayed in the LDEV table.
