HP StorageWorks XP Performance Advisor Software v4.6 User and Troubleshooting Guide (T1789-96094, June 2010)

2. Click Query. If you do not select a last collection date and time, the current last collection date
and time is considered for querying the data.
XP Performance Advisor verifies the performance data available for the selected XP array, retrieves
data for the latest time stamp (from the last collection date and time you specified), and displays
on the LDEV table.
IMPORTANT:
• For an XP24000 type array, the performance data can be collected on 64000 LDEVs
(64K binary (65,536)).
• For XP arrays with external LDEVs, – is displayed in the ACP PAIR list, in the LDEV table.
This is because the external LDEVs do not have any valid ACP pair associated with them.
Hence, all the external LDEVs for an array are grouped under –. The XP24000, XP20000,
XP12000, XP10000, and SVS200 type arrays support external LDEVs.
The data is displayed in either black or blue text. Black text indicates that no additional information
is available for that field. Blue text indicates hyper links that you can click to view the respective
resource information in a separate browser window. Most of the hyper links display performance
graphs of resources for the associated metrics in the Chart Work Area; all other hot links display
information in different formats.
IMPORTANT:
• For the XP24000, XP20000, XP12000, XP10000, and SVS200 type arrays, double-
click an SLPR or CLPR value to view the details for that SLPR or CLPR. For more informa-
tion, see “SLPR detail view” on page 205 and “CLPR detail view” on page 206.
• For Snapshot and THP pools, the SLPR and CLPR details are displayed only for the asso-
ciated LDEVs in the LDEV table. The SLPR and CLPR details are not displayed for the
LDEVs that form the Snapshot and THP pools.
• A THP or Snapshot pool should have at least one VVOL assigned to it for the THP or
Snapshot pool to be displayed in the LDEV table.
3. Sort the data displayed by selecting one of the above mentioned from the Sort by list.
You can also select the sort by category before querying the data, so that the data collected is
automatically sorted based on the selected category and displayed in the LDEV table. The sorting
is done on all the LDEV records that are displayed in the LDEV table, and is not limited to a per
page basis.
Configuring column settings
You can view data for various resource types in the LDEV table. By default, XP Performance Advisor
displays data for only the following resources:
• LDEV ID: The identification number for the LDEV
• RAID Group: The RAID group to which the LDEV belongs
• ACP Pair ID: The card letters for the Array Control Processor pair
• CHIP Port ID: The port name for the Client Host Interface Processor (CHP) port
• Host Group: The host group to which the host belongs
For the above mentioned, the performance values of LDEVs for the following metrics are also displayed:
