HP XP P9000 Performance Advisor Software - Manual (Page 323)

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.
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 another 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 HP XP 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
processing 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 v70-03-42-00-00 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 HP XP P9000
Performance Advisor are displayed in the Select Components list under Start Collections tab.
2. Click the plust (+) sign for an XP or a P9000 disk array serial number to view the component
categories.
The following image shows the MP selection for MPB-1MA under the MP Blade(s) component
category for 53012, which belongs to the P9500 Disk Array type.
