Removing host agent information from P9000 Performance Advisor
IMPORTANT:
• You can remove a host agent record when its status shows as Requested or Received under Status.
• If an XP or a P9000 disk 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 XP or P9000 disk array is still available in P9000 Performance
Advisor. This is because, that XP or P9000 disk array is still connected to the other host agent.
• The existing configuration and performance data can be purged for those XP and P9000 disk
arrays that are no longer monitored by P9000 Performance Advisor.
To remove a host agent record:
1. Click Monitoring > Array View in the left pane.
The Array View screen appears.
2. Click the Host Information tab.
3. Select the host agent records that must be removed from P9000 Performance Advisor.
4. Click Remove Host. The Remove Host button is enabled only when you select a host agent record.
P9000 Performance Advisor 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 the following data for
the XP and the P9000 disk arrays connected to the host agent are also removed. Initiate a new
configuration collection on the XP and the P9000 disk 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 tab. For more information
on restarting host agent services, refer to the HP StorageWorks P9000 Performance Advisor Software
Installation Guide.
