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

I need to monitor response time for a particular RAID group over a shorter dura-
tion. Can I collect performance data for less than 60 seconds using P9000 Per-
formance Advisor?
No. The minimum duration for collecting performance data using P9000 Performance Advisor is at
least one minute. To view data for less than a minute duration, use P9000Watch or the real-time
charting feature in P9000 Performance Advisor.
Can I view real-time performance graphs for multiple XP and P9000 disk arrays
simultaneously?
Yes. You can collect real-time performance data and view real-time graphs for multiple XP and P9000
disk arrays. However, ensure that the real-time data collections are happening through dedicated
host agents.
For example, if host agent_A and host agent_B are connected to both XP disk array_1 and XP disk
array_2, initiate a real-time data collection on XP disk array_1 through host agent_A and on XP disk
array_2 through host agent_B. You cannot use host agent_A to collect real-time data for both XP disk
array_1 and XP disk array_2.
Can I initiate multiple instances of real-time data collections for an XP or a P9000
disk array, or multiple XP and P9000 disk arrays using the same host agent?
No. You cannot initiate another instance of real-time data collection using a host agent that is already
collecting real-time data for an XP or a P9000 disk array. At a time, a host agent can only handle
one instance of real-time data collection.
If an XP or a P9000 disk array is connected to two host agents, is it possible to
simultaneously initiate real-time data collections on the XP or P9000 disk array
through both the host agents?
Yes. It is possible to initiate real-time data collections on the XP or P9000 disk array through both the
host agents, as each host agent will still be handling only one instance of real-time data collection.
Can I use a host agent for real-time data collection, if the real-time server is
getting updated on that host agent?
No. Wait for the real-time server update to complete, if you want to use the same host agent for a
real-time data collection.
Can I save a real-time chart for my future reference?
No. There is no option to save real-time charts.
Can I view historic data for an XP or P9000 disk array using the real-time
charting functionality?
No. Real-time charting functionality can only be used to view the point in time data for your XP or
P9000 disk array. If you want to view the historic data, use the Charts functionality provided by
P9000 Performance Advisor.
