Starting performance data collection in case of a disk failure
The
performance data collection might stop on all the XP and the XP7 disk arrays connected to a
host,
if the command device used belongs to an array group where a disk failure occurred. To
restart
performance data collection:
1. Under the Host Information tab, select the host (on which performance data collection has
stopped) and click Request Info. The status for the selected host changes to Received after the
information is collected from the host. For more information, see
“Requesting host agent
updates” (page 47) .
2. Under the Performance Collection tab, delete and recreate the performance schedules with a
new name for the selected host. The schedule is enabled automatically and the performance
data collection begins. The previous collection data is still retained.
Viewing performance data collection schedules
After
creating a schedule, click the View link under Components or the View button. The list of
selected
components, respective data collection frequencies, and the command device chosen
for
data collection are displayed. In addition, the port type, such as FCoE (applicable only for
P9500/XP7
disk arrays) is also displayed for a port.
NOTE:
•
The
View button is enabled only when you select an XP or an XP7 disk array record under
the
Performance Collection tab.

Editing performance data collection schedules
You can add or remove components from an existing performance data collection schedule, and
edit the frequency of data collection. When you edit a performance data collection schedule, you
might notice missing data points for components in the subsequent collection cycle before HP XP7
Performance Advisor starts collecting data for the new set of components and frequency.
To edit a performance data 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/XP7 disk array record for which you
want
to modify the associated performance data collection schedule.
3. Click
Edit. The Edit button is enabled only when you select an XP or an XP7 disk array
record under the Performance Collection tab.
The schedule details appear and the selected components are highlighted for your reference
in the respective component type lists.
4. Modify the schedule settings as required. For more information, see “Creating or viewing a
performance data collection schedule” (page 62) .
5. Click Save to commit the changes.
The updated frequency is displayed under Frequency. In the subsequent data collection cycle,
HP XP7 Performance Advisor collects data for the new set of components as per the new
frequency.
