HP StorageWorks P9000 Performance Advisor Software v5.4 Troubleshooting and FAQs Guide (T1789-96336, April 2012)

If your P9000 disk array is already connected to two host agents, you can start separate instances
of real-time data collections simultaneously through both the host agents. In this case, P9000
Performance Advisor collects real-time data for a set of five LDEVs through each host agent.
I am seeing the following error message when I try to plot a real-time chart for
the LDEV, 00:01 on the RealTimeCharting screen. What does the error message
indicate?
The selected component does not have any activity happening
currently or is no longer present in the XP array.
It implies that the selected LDEV, 00:01 is currently not processing any I/O requests. In such a case,
P9000 Performance Advisor does not plot real-time chart for the LDEV, 00:01, as it is considered as
an unused resource.
I am trying to plot real-time charts for the LDEVs, 00:01, 00:02, and 00:03 on
the RealTimeCharting screen. However, I can see the real-time charts for only
the LDEVs, 00:01 and 00:02. What does it indicate?
It implies that the LDEV, 00:03 is an unused resource. Therefore, you cannot see a real-time chart for
this resource. P9000 Performance Advisor does not plot real-time charts for LDEVs and RAID groups
that are currently not processing any I/O requests.
When I click Update RealTimeServer on the RealTimeCharting screen for a host
agent, how long does it take for the host agent to get the latest configuration
data from the associated XP or P9000 disk array?
The process of updating the real-time server on a host agent takes about 20 - 30 minutes.
Port 8331 is in use on my management station. Which is the file that I should
open to modify the port number?
Open the realtime.properties file and provide the new port number against the Port.Number
field.
• On the management station, the realtime.properties file is located in the %HPSS_HOME%/
pa/properties folder.
• On the host agent, the realtime.properties file is located in the xppa/realtime/config
folder.
NOTE:
From P9000 Performance Advisor v4.6 onwards, the realtime.properties file is renamed as
xprmihaserver.properties.
