HP StorageWorks P9000 Performance Advisor Software v5.2 Install Guide (T1789-96317, May 2011)

5 Using P9000 Performance Advisor
After installing the P9000 Performance Advisor and the host agents, start collecting the configuration
and the performance data for the XP and the P9000 disk arrays.
You can initiate configuration data collection for only one XP or P9000 disk array at a time, and
select only one command device through which you can collect data for the XP or the P9000 disk
array. To frequently monitor and collect performance data for the XP and the P9000 disk arrays,
create two performance data collection schedules each for an XP or a P9000 disk array. The
components that are not selected as part of the first schedule are automatically added to the second
schedule that you create. You can set different collection frequencies for components that belong to
the DKC, ports, and the RAID group resource types, and also enable the schedules for automatic
updates. The collection frequency set for a RAID group in a schedule is applicable for any component
of the continuous access journal, snapshot, ThP, and the external RAID group types. It is applicable
only if they are selected for the performance data collection.
• “Collecting configuration data” on page 90
• “Collecting performance data” on page 94
IMPORTANT:
• Ensure that the date and time on the management station, and the hosts are synchronized with
the local time zone to receive accurate configuration data.
• If you are collecting performance data for the first time, it takes longer than usual for P9000 Per-
formance Advisor to collect the data. The subsequent performance data collection on the XP and
the P9000 disk arrays is as per the time specified in the Frequency section.
Requesting host update
IMPORTANT:
Perform this procedure only if you have made changes to your host agent or to the XP and the P9000
disk arrays connected to your host agent. If no changes are made, you can directly collect the
configuration and performance data for your XP and P9000 disk arrays.
To request a host update:
1. Log on to P9000 Performance Advisor. For more information, see “Launching P9000 Performance
Advisor” on page 64.
2. Click Array View in the left pane.
3. Click the Host Information tab on the Array View screen.
4. In the Host Information table, select the host agents whose configuration details you want to
update in P9000 Performance Advisor.
