Introduction
HP XP7 Performance Advisor interacts with the XP and the XP7 disk arrays through hosts that have
the operating system specific HP XP7 Performance Advisor host agents installed. These hosts form
the channel of communication between HP XP7 Performance Advisor and the XP and the XP7 disk
arrays. Once the host agents are installed, the corresponding records automatically appear under
the Host Information tab on the Array View screen. The configuration summary details of the
associated XP and theXP7 disk arrays are also displayed on the relevant HP XP7 Performance
Advisor screens. If command devices are configured on the XP and the XP7 disk arrays, the
corresponding command device details are displayed for each XP and XP7 disk array record under
the Configuration Data tab on the Array View screen. You can request an update from a host agent
every time you make the configuration changes to the host agent or their associated XP and the
XP7 disk arrays. You can remove records for the host agents that are no longer connected to the
management station.
After the host agents are discovered, start the configuration data collection followed by the
performance data collection for an XP or an XP7 disk array using its corresponding command
device. The configuration data collection can be a one-time activity or scheduled periodically on
a daily, weekly, or a monthly basis. It can be collected using the outband mode of data collection.
During a scheduled configuration data collection, the data pertaining to the new components are
automatically included in the latest configuration data. During a one-time configuration data
collection, the data on new components cannot be collected after the configuration collection is
complete. You must perform another one-time configuration data collection to receive the updated
configuration data.
IMPORTANT:
HP XP7 Performance Advisor v6.0 supports only the outband mode of configuration
data collection. If you select the HP XP7 Performance Advisor Management Station 6.0 does not
support the inband mode of configuration data collection check box while installing or upgrading
from any previous version to v6.0, the schedules that are created using the inband mode of data
collection are deleted.
After the configuration data collection is complete, start the performance data collection by creating
schedules and including components that need to be monitored. You can collect performance data
for the RAID groups, DKCs, ports, continuous access journals, ThP, and the external RAID groups.
In addition, you can also specify the frequency of collection for each of the selected components.
Further, you can enable a performance data collection schedule to automatically monitor and
collect the performance of new components (RAID groups and ports). The components discovered
during the scheduled configuration data collection are automatically added to the performance
data collection schedules that are enabled to automatically monitor new components. For more
information, see
“Enabling performance collection schedules for automatic updates” (page 66)
.
Confirmatory records on all the events generated for host updates, configuration, and the
performance data collection activities are displayed on the Event Log screen. To view the Event
Log screen, click Event Log in the left pane. For more information on managing events, see
