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

SolutionError messageScenario
When a realtime server update is
requested, you cannot initiate realtime
monitoring using the same host agent. Wait
for the update to be completed, or select
another host agent.
Real Time Server Configuration
data is getting updated on the
selected HA. Please select any
other HA.
Real-time monitoring fails if it is attempted
on a host agent with a pending server
update request.
Either the selected component is no longer
present on the array or there is no IO
activity on the component.
The selected component does not
have any activity happening
currently or is no longer
present in the array.
Real-time monitoring is attempted but, charts
are not displayed.
Verify if the host agent name displayed in
P9000 Performance Advisor is correct.
Also, verify if the real-time server (HP
P9000 Performance Advisor RealTime
Server) is active on the host agent.
Performance Advisor could not
recognize the Real Time Server
on the host agent <host agent
name>. This could be due to the
Real Time Server not running on
the selected host agent or the
host agent name is not found.
Realtime monitoring is attempted. However,
you are not able to connect to the real-time
host agent.
Real-time performance graphs are not
displayed for LDEVs and RAID groups that
are currently not processing any I/O
requests (described as unused components).
• Case 1: You select three LDEVs,
00:00, 00:01 and 00:02 for which
you want to plot the real-time perform-
ance graphs. Among these LDEVs,
00:02 is an unused LDEV. Hence, the
real-time performance graphs are dis-
played only for 00:00 and 00:01
LDEVs.
• Case 2: You select only one LDEV,
00:02 that is currently an unused
component. The RealTimeChart screen
displays the following message:
The selected component does
not have any activity happen-
ing currently or is no
longer present in the XP or
the P9000 disk array.
The selected component does not
have any activity happening
currently or is no longer
present in the XP or the P9000
disk array.

Perform the following steps:
1. Check if the following services are
active:

ance Advisor Database Listener
2. Refresh the Dashboard screen to view
