Remove Host Agent Information; About Configuration Data Collections - HPE XP7 User Manual

If there are any configuration changes in the associated XP and the XP7 disk arrays, PA also updates
these details on the relevant screens. For example, if the updated information is about a new command
device, an additional record for the new command device is also displayed under the Configure
Information pane in Summary View > Array Summary.
To collect configuration data from a reconfigured XP or XP7 disk array, perform the above-mentioned
steps. During the next data collection cycle, the host collects the configuration data again from the
reconfigured XP or XP7 disk array and displays in the Array Summary screen. This process avoids
inconsistencies in the performance data collected for the reconfigured XP or XP7 disk arrays.

Remove host agent information

If an array is connected to two host agents, both of which communicate with the same management
station and one of the host agent record is removed, the configuration and the performance data for that
array is still available in PA. This is because, that array is still connected to the other host agent.
You can purge the existing configuration and performance data for those arrays that are no longer
monitored by PA.
Prerequisites
Ensure that the Status of the host agent is green. You can remove a host agent record when its status
shows as Requested or Received under Status.
Procedure
1. From the main menu, navigate to Collections > Host Information.
2. Select the host agent records that you want to remove from PA.
3. Click Remove Host.
The Remove Host button is enabled only when you select a host agent record.
PA deletes the host agent record and logs a confirmation on the Event Log screen.
When you remove a host agent, information about the command devices and all the information
pertaining to the arrays connected to that host agent are also removed. Initiate a new configuration
collection on the arrays, and recreate or reconfigure the following parameters:
• Configuration data
• Performance schedules
• Report schedules
• Alarm configuration data
• Custom groups
If you want to view the host agent records again, restart the host agent services on that host. A record for
the host agent is automatically displayed under the Host Information pane. For more information on
restarting host agent services, refer to the HPE XP7 Performance Advisor Software Installation Guide.

About configuration data collections

After the host agents are discovered, you can start the configuration data collection for the arrays using
