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

• Check if another user accessing the same management station has triggered another real-time
performance data collection. If you try to connect to a host agent that is already collecting the
real-time data initiated through another instance of P9000 Performance Advisor, the existing
connection is discontinued and the above-mentioned error message is displayed.
Resolution
To overcome the issue, perform the following steps:
1. Verify if the real-time server (HP P9000 Performance Advisor RealTime Server) is running on the
host. Restart the service if it has stopped.
For P9000 Performance Advisor Real-time to run, the management station (MS) must be able to
ping the host agent (HA) using the hostname(FQDN) of the HA.
2. Verify if the host agent name displayed in P9000 Performance Advisor is correct. It appears in
the HostAgent list on the RealTimeChart screen.
You can also ping the host agent to check if it is responding to your requests. The host agent
name should be the same as displayed under HostAgent in the RealTimeChart screen.
Also, verify if there is a correct mapping of the IP address to the host name. You can find this
mapping information in the <Install_drive>:\Windows\System32\drivers\etc\hosts
file on your management station. If the mapping between the IP address and the corresponding
host name is incorrect, edit the hosts file to replace the existing IP address with the new one
and save the changes. Ensure that the IP address and the host name are separated by a space.
