HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

The port type, such as Fibre, Ficon, Escon, or FCoE (applicable only for P9000 disk arrays) is
also displayed beside the port ID.
• CHA MP: Displays the MP associated with the port.
The details of the partner port that is associated with the same MP is also displayed. The
partner port record appears in grey. When you plot the usage graphs for these ports (primary
and partner ports), you will be able to analyze whether the partner port is overloading the MP
that is also associated with the primary port.
IMPORTANT:
The CHA MP data is not applicable for the P9000 disk arrays.
If your application is associated with the XP disk arrays, appropriate status icons are displayed for
the following based on the corresponding component utilization:
• MP Util (%)
• Write Pending (%)
• DKA Util (%)
• RG Util (%)
If your application is associated with the P9000 disk arrays, appropriate status icons are displayed
for the following based on the corresponding component utilization:
• Write Pending (%)
• RG Util (%)
• MP Blade Util (%)
NOTE:
The DKA Util (%) metric is not applicable for the P9000 disk arrays.
These status icons can be ( , , or ) and derived based on the threshold values that you set on
the Threshold Settings screen. For more information on the status icons, see “XP/P9000 array
health” on page 130. For more information on setting threshold values, see “Configuring dashboard
threshold settings” on page 122.
You can also forecast the component utilization based on the array type.
• For an XP disk array, forecast the DKA, RAID group, cache write pending, and the MP utilization.
• For a P9000 disk array, forecast the cache write pending, MP blade, and the RAID group utiliza-
tion.
For more information, see “Forecasting utilization” on page 317.
Viewing data for additional metrics
The additional set of metrics are listed in the Metrics list above the respective LDEV, Port, CLPR, and
the RAID groups tables. These are metrics for which you can view data for the same set of LDEVs,
ports, CLPRs, and RAID groups that are initially displayed for the selected application, host, or the
WWN.
