Why is the host agent record still displayed in the Host Information table (Monitoring+Array
View+Host Information) even after it is removed from the host?
After you remove the host agent, the corresponding host agent record is still visible on the HP XP
P9000 Performance Advisor's Host Information screen. Perform the following steps to manually
remove the host agent record from the management station:
1. Click Monitoring+Array View in the left pane.
2. Click the Host Information tab.
3. Select the host agent record that should be removed from HP XP P9000 Performance Advisor.

the Event Log screen.
When you remove a host agent, the data about the command devices that are exposed to its host
and the following data for the XP and P9000 disk arrays are also removed. You should initiate a
new configuration collection on the XP and P9000 disk arrays and also create, or configure the
following parameters again. For more information, see HP XP P9000 Performance Advisor Software
