HP StorageWorks XP Performance Advisor Software v4.6 User and Troubleshooting Guide (T1789-96094, June 2010)

When the performance data collection is in progress, you can perform the following functions. Allow
XP Performance Advisor to complete at least two performance data collection cycles before you
proceed with the following tasks. This is to ensure that sufficient data is available that can be projected
on the respective screens:
• View a graphical representation of the performance of resources for different metrics and duration
that you specify. For more information, see “Plotting charts” on page 213.
• View performance summary of resources on the Array View screen. For more information, see
“Viewing performance summary for the XP array” on page 176.
• Configure alarms on resources, so that XP Performance Advisor can send appropriate alarm noti-
fications. For more information, see “Adding or removing metric values” on page 121.
• Create custom groups for a set of LDEVs that you want to frequently monitor. For more information,
see “Creating custom groups” on page 84.
• Create and schedule reports to view the performance data of resources for different metrics, and
duration that you specify. For more information, see “Generating, saving, or scheduling re-
ports” on page 260.
In case of performance data collection failures, appropriate failure messages are displayed on the
Event Log screen. XP Performance Advisor can also dispatch email notification about the collection
failure to the intended recipient. To receive performance data collection failure notification, you must
configure the appropriate email notification settings. For more information, see “Configuring email
and SNMP settings” on page 76.

Enabling performance collection schedules for automatic updates
You can enable performance data collection schedules to automatically collect performance data for
newly discovered RAID groups and ports. New RAID groups and ports in an XP array are discovered
during scheduled configuration data collection. They are automatically appended to the existing list
of RAID groups and ports in the corresponding performance data collection schedule that is enabled
to collect performance data for new resources. The newly discovered resources are added to only
those performance data collection schedules that are enabled for automatic updates. XP Performance
Advisor collects data for new RAID groups and ports from the subsequent data collection cycle.
The new resources can also comprise of virtual volumes – THP, Snapshot, XP Continuous Access
Journals, and External RAID groups. They are automatically added to only those performance data
collection schedules that are already collecting performance data for these virtual volumes. It is
irrespective of whether the performance data collection schedule is enabled to receive automatic
updates. The virtual volumes cannot be split across two schedules.
For a schedule to automatically collect data for the new set of RAID groups and ports, select the Add
new RAID Groups, Ports to this schedule check box while creating a performance data collection
schedule. The following table provides scenarios on when a schedule can be enabled for automatic
updates.
