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).

IDs.

LDEV ID

Select RAID Groups to sort LDEV data based on the
associated RAID groups.

RG(s)

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 LDEVs (64K
binary (65,536)).

For

the XP, XP7 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 an XP7 disk array are grouped under –. The

P9500,

XP24000, XP20000, XP12000, and XP10000 Disk Arrays support external

LDEVs.

For the XP24000, XP20000, XP12000 and XP10000 Disk Arrays, double-click an SLPR
or CLPR value to view the respective details. For more information, see

“SLPR detail

view” (page 228)

and

“CLPR detail view” (page 228)

.

For P9500/XP7 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 P9500/XP7 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.
