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

IMPORTANT:
The following are important notes on the real-time performance data collection:
• You can configure only one instance of the real-time performance data collection for an XP or a
P9000 disk array through the connected host agent. You cannot use the same host agent for an-
other real-time performance data collection until the current collection stops. However, if an XP
or a P9000 disk array is connected to two host agents, configure separate real-time data collection
through each of the host agents.
• The real-time performance data cannot be collected for a combination of components (example,
LDEVs and RAID groups) that belong to the same XP or P9000 disk array. Also, the real-time data
cannot be collected for similar components (example, LDEVs or RAID groups) that belong to multiple
XP and P9000 disk arrays.
• At a time, ensure that only one instance of P9000 Performance Advisor collects the real-time
performance data from an XP or a P9000 disk array through the respective host agent.
• The real-time performance graphs are not displayed for components that are currently not pro-
cessing any I/O requests (described as unused components).
• The external RAID groups and VVols are not displayed for an XP or a P9000 disk array. Further,
only the first RAID group from a concatenated RAID group is displayed for your selection.
• To view correct metrics for P9500 disk arrays, ensure that v70-03-30 is the minimum firmware
version on the disk array. Similarly, for XP24000 disk array, ensure that v60-08-05-00/00 is the
minimum firmware version on the disk array.
To start a real-time data collection:
1. Click Troubleshooting > RealTime in the left pane.
The RealTime screen appears. The list of XP and P9000 disk arrays monitored by P9000
Performance Advisor are displayed in the Select Components list under Start Collections tab.
