DescriptionXP or P9500 Disk Array main categories – component se-
lection tree
Comprises of the individual ThP pool IDs and the associated RAID
groups and VVols. The RAID groups further display the list of
associated physical LDEVs. The ThP pools are displayed for the
P9000 disk arrays, such as the P9500.
The ThP pools are also displayed only for the XP24000 Disk Array
in the XP disk array family. For more information, see “THP Pool
navigation path” on page 283.
THP Pool
Comprises of the individual snapshot pool IDs, the associated RAID
groups, and VVols (PVOLs and SVOLs). The RAID groups further
display the list of associated physical LDEVs. The snapshot pools
are displayed for the P9000 disk arrays, such as the P9500.
The snapshot pools are also displayed only for the XP24000,
XP20000, XP12000, XP10000, and the SVS200 Disk Arrays. For
more information, see “Snapshot Pool navigation path” on page 285.
Snapshot Pool
Comprises of volumes that are used in the business copy or the
continuous access transactions. The business copy volumes comprise
of individual physical LDEVs. The continuous access volumes
comprise of the journal pools that have LDEVs configured to be
part of the journal pools. The continuous access volumes can be
configured on the P9000 disk arrays, such as the P9500.
They can also be configured on the XP24000, XP12000, XP10000,
SVS200, XP20000, and the SVS400 Disk Arrays. For more
information, see “Replication Volumes navigation
path” on page 288.
Replication Volumes
Comprises of the individual LUSE masters that have set of associated
components (LDEVs). For more information, see “LUSE navigation
path” on page 290.
LUSE
Comprises of the individual host groups that display the associated
ports and LDEVs. For more information, see “Host Groups
navigation path” on page 292.
Host Groups
Comprises of the external RAID groups that are managed by the
XP and P9000 disk arrays. For more information, see “Ext-RG(s)
navigation path” on page 294.
Ext-RG(s)
Comprises of the individual drive types that are available on the
selected XP and P9000 disk arrays. Also, includes the RAID groups
for each of the drive types. The RAID groups further display the list
of associated physical LDEVs. For more information, see “Drive
types navigation path” on page 296.
Drive Types
The above categorization helps you to view the overall performance of an XP or a P9000 disk array
through various channels of selection.
For example, if your application's response time is high, following is one of the ways to identify the
issue in the XP disk array that is processing your application requests:
1. Plot the performance graphs of all the ports (Front-end > Ports) to identify the port that is doing
maximum I/Os.
2. For that port, identify the associated host (Host Groups > Host > Ports).
