HP XP P9000 Performance Advisor Software v5.5.1 Release Notes (T1789-96349)

• Real-time charts and historical charts cannot be plotted simultaneously, as the plotting of
real-time data stops when the plotting of historical data is in progress.
In such a case, the following error message appears on the Charts screen:
The selected component may no longer be connected to the array or does not have any activity
happening currently. Please verify if the selected component is currently active. If you see that
the selected component is active, then please try recreating the device files as the device file
may not be accessible by RealTimeServer.
When historical data is plotted, ensure that the real-time data charting is not started.
Current Status: Fix is being investigated, no ETA as of P9000 Performance Advisor v5.5.1
release date.
• When you perform the inband mode of configuration data collection, the following behaviors
are observed:
◦ The snapshot V-Vol numbers displayed in the Array View Summary screen are inconsistent.
Workaround: HP recommends that you perform outband mode of configuration data
collection to view the snapshot V-Vol numbers.
Current Status: Fix is being investigated, no ETA as of P9000 Performance Advisor v5.5.1
release date.
◦ The number of LDEVs associated with an MP blade are inconsistent. This behavior is
observed in the Array View - MP Blade screen.
Workaround: HP recommends that you perform outband mode of configuration data
collection to view the LDEV numbers.
Current Status: Fix is being investigated, no ETA as of P9000 Performance Advisor v5.5.1
release date.
• When you plot a chart for more than 250 components, the performance graphs for only the
first 250 components are displayed in the chart.
Workaround: To plot performance graphs for more than 250 components, you must plot the
graphs for the first 250 components in the existing chart window and then plot the graphs for
the remaining components in a new chart window.
Current Status: Fix is being investigated, no ETA as of P9000 Performance Advisor v5.5.1
release date.
• When a manual purge or data archival process is active, occasionally, you might notice that
the management station overlooks data samples received from the host agents.
The purging may take hours to complete based on the database size. HP recommends that
you stop the performance collection before starting the purge to overcome missing data points
during purge.
Current Status: This will be fixed in the subsequent release.
• For XP/P9500 disk arrays with concatenated parity groups, you might notice 4D+4D RAID
type instead of two 2D+2D concatenated parity groups in the Performance Estimator screen.
Current Status: Fix is being investigated, no ETA as of P9000 Performance Advisor v5.5.1
release date.
• While charting backend transfer metrics for DKAs or ACPs with concatenated RAID groups,
you might observe that the total write tracks do not match the sum of the individual DKA or
ACP metrics.
Current Status: This will be fixed in the subsequent release.
