HP StorageWorks P9000 Performance Advisor Software v5.4 User Guide (T1789-96328, April 2012)

• “Stopping real-time performance data collection” on page 353
Starting real-time performance data collection
Prerequisites
• HP recommends that you dedicate a command device for the real-time performance data collection,
so that it is not used by P9000 Performance Advisor for the regular configuration or performance
data collection.
• If there have been configuration changes on the XP or the P9000 disk array for which you want
to collect the real-time performance data, the following informational message appears when you
select components and start plotting the real-time graphs:
The <XP or P9000 disk array> configuration data available in the Real
Time Server is not in sync with the configuration data available on
Performance Advisor. This could occur due to the following reasons:
Command device is invalid, <XP or P9000 disk array> is no longer con-
nected, or selected components are not available on the selected <XP
or P9000 disk array>.
Perform the following steps to ensure that the same configuration data for the selected XP or the
P9000 disk array is available on both the host agent real-time server and P9000 Performance
Advisor:
1. Request a host update. For more information, see “Requesting host agent updates” on page 56.
2. Initiate the configuration data collection from P9000 Performance Advisor, so that the latest
configuration data is available for the XP or the P9000 disk array. For more information, see
“Collecting configuration data” on page 62.
3. For the P9000 Performance Advisor host agent that is connected to the selected XP or P9000
disk array, update its real-time server with the latest configuration data of the XP or the P9000
disk array. Click Update RealTime Server on the RealTime screen for the host agent to receive
the latest configuration data. Updating the real-time server lasts for about 20 - 30 minutes
and the following informational message appears after the update is complete:
Real Time Server Configuration Collection update done for Hostagent.
You can then proceed with the real time data collection and plotting
of charts.
If you want to start the real-time collection using the same host agent for which the real-time
server update is in progress, the following error message is displayed:
Real Time Server Configuration data is getting updated on the selec-
ted HA. Please select any other HA.
You must wait for the real-time server update to complete if you want to use the same host
agent.
Ensure that the above-mentioned steps are performed before you initiate a real-time performance
data collection for a P9000 disk array (such as the P9500) or for the following XP disk array
models: XP24000, XP20000, XP12000, or XP10000.
