HP XP P9000 Performance Advisor Software - Manual (Page 73)

Creating performance data collection schedules
IMPORTANT:
•
Only one schedule can be created on a selected command device. For a better performance, select
a maximum of two command devices that belong to different ports.
• A schedule cannot be created for the same XP or P9000 disk array through two different host
agents.
• HP recommends that you should allow two minutes per 1,000 LDEVs for the management station
to keep up with the collection. P9000 Performance Advisor collects the performance data on all
the LDEVs. The collection is not limited to the number of LDEVs that the host station is mapped to
use.
• You can set the collection interval for the performance data collection to a minimum of one minute
or a maximum of 60 minutes. HP recommends a collection frequency of five minutes.
• If you select all the seven component types, you must set a minimum frequency of 15 minutes and
a maximum of 60 minutes.
• For viewing and collecting the performance data for large number of LDEVs, you must configure
the java heap size settings in both the management station and the host system. For more inform-
ation, see “
Increasing the maximum number of LDEVs ” on page 83.
• If multiple SLPRs are configured in an XP disk array, select the command device in the SLPR0.
However, if you select a command device in the SLPR1 or SLPR2, the configuration information
associated with the SLPR0 cannot be accessed due to security implementations.
NOTE:
SLPR does not exist in the P9000 disk arrays. So, the above-mentioned point is not applicable
for the P9000 disk arrays.
• If configured in an XP or a P9000 disk array, it is mandatory that you select all the continuous
access journal, snapshot, and the ThP components from the respective component type lists.
• HP recommends that you clear the cache on your IE browser before creating a schedule.
To create a performance collection schedule:
1. Click Monitoring > Array View in the left pane.
The Array View screen appears.
2. Click the Performance Collection tab and select the XP or the P9000 disk array, for which you
want to schedule performance data.
Alternatively, click an XP or a P9000 disk array icon displayed above the Performance Collection
tab to view the corresponding set of records highlighted in the Performance Collection table. The
existing set of records are automatically sorted to display the command devices that belong to
the selected XP or P9000 disk array at the beginning of the Performance Collection table.
