Starting performance data collection in case of a disk failure
Performance data collection may stop on all XP arrays connected to a host, if the command device
used belongs to an array group where a disk failure occurred. To restart the 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” on page 40.
2. Under the Performance Collection tab, delete and recreate the performance schedules for the
selected host. The schedule is enabled automatically and the performance data collection begins.
The previous collection is still retained.
Viewing performance data collection schedules
After creating a schedule, click the View link under Components to view the list of selected resources
and the respective data collection frequencies. In addition, the selected command device name is
also displayed.
NOTE:
• The Stagger Collection is shown as false, if you have not configured a staggered collection
schedule.
• The View button is enabled only when you select an XP array record under the
Performance Collection tab.

Editing performance data collection schedules
You can add resources or remove resources from an existing performance data collection schedule,
and also edit the frequency of collection. When you edit a performance data collection schedule, you
may see missing data points for the resources in the subsequent collection cycle before XP Performance
Advisor starts collecting data for the new set of resources and frequency.
