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:
