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 selected 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 an XP7 disk array or for the following XP disk array models: P9500,
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
an XP7 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 an XP7 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 XP7 disk array. Also, the real-time
data
cannot be collected for similar components (example, LDEVs or RAID groups) that
belong
to multiple XP and XP7 disk arrays.
•
At
a time, ensure that only one instance of HP XP7 Performance Advisor collects the real-
time
performance data from an XP or an XP7 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 an XP7 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 the firmware version on the disk
array
should be between v70-05-02-00/00 to v70-06-13-00/00. Similarly, for XP24000
disk
array, ensure that firmware version should be between 60-04-13-00/00 to
v60-08-37-00/00.
To view correct metrics for XP7 disk arrays, ensure that v80-01-01/ 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 XP7 disk arrays monitored by HP XP7
Performance
Advisor are displayed in the Select Components list under Start Collections tab.
2.
Click
the plust (+) sign for an XP or an XP7 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 53120, which belongs to the P9500 Disk Array type.
Additionally, the following are displayed:
