HP StorageWorks XP Performance Advisor Software v4.6 User and Troubleshooting Guide (T1789-96094, June 2010)

• 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.
• Error occurred while connecting to Real Time Server. This could be due
to the Real Time Server not running on the host agent, or the same host
agent is already being used for real time collection by another instance
of Performance Advisor.
It may be due to the following reasons:
• Real-time service is not running on the selected host agent.
• XP Perf Advisor host agent is not responding to your requests, as the specified host name does
not exist.
• Check if another user accessing the same management station has triggered another real-time
performance data collection. If yes, then you need to connect to array using some other HA.
To overcome the issue, perform the following steps:
1. Verify if the host agent name displayed in XP Perf Advisor is correct. This can be done by pinging
the host agent to see if it is responding to your requests. You should enter the fully qualified domain
name ([servername].[domain name]) of the host agent in the command prompt window. You can
get the fully qualified domain name from the HostAgent list on the RealTimeChart screen.
2. Verify if the real-time server (HP XP Performance Advisor RealTime Server) is running on the host.
Restart the service if it has stopped. Additionally, if it is a Linux or Unix host agent, check for the
following entry under /etc/hosts: 127.0.0.1 <Server HostName> localhost.loc-
aldomain localhost
If the above mentioned entry is present, do the following to resolve the issue:
a. Stop the Web NMS server.
b. Remove the <Server HostName> entry from /etc/hosts. Following should
be the entry: 127.0.0.1 localhost.localdomain localhost
c. Restart the network of the server by executing the following commands from /etc/hosts/
rc.d/init.d directory:
• ./network stop
• ./network start
d. Start the Web NMS server and connect the client again.
Unfinished configuration data collection error
On a windows machine, if configuration data collection does not finish or the
PerformanceAdvisorXP.log displays the following error: PerformanceAdvisor: Failed
to start config data collector transfer for <Array Serial #>:
com.hp.xpsl.hostagent.RmlibException: RMLIBbased DKC configuration is
empty for <Array Serial #>
To resolve the issue:
1. Create a GUID for the devices. See the HP StorageWorks Performance Advisor Software Install-
ation Guide for configuring the GUID.
2. Restart host agent services.
3. From the list of host records under the Host Information tab (Array View > Host Information),
select the host record on which performance data collection stopped.
