HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

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 after the next auto refresh
cycle. For more information on restarting host agent services, refer to the HP StorageWorks P9000
Performance Advisor Software Installation Guide.
Collecting configuration data
You can collect the configuration data for the XP and the P9000 disk arrays in the following ways:
One-time configuration data collection: Use this collection type if you want to collect the configur-
ation data only once. Any new configuration changes to the XP and the P9000 disk arrays, such
as new components that are added after the collection completes are not captured in the existing
configuration collection.
Scheduled configuration data collection: Use this collection type if you want to schedule the con-
figuration data collection periodically on a hourly, daily, weekly, or a monthly basis. Based on
the schedule frequency, P9000 Performance Advisor collects the updated configuration data from
the XP and the P9000 disk arrays. If you want P9000 Performance Advisor to automatically collect
the performance data for new components, you must enable the corresponding performance data
collection schedules to automatically accept and monitor the performance of new components.
For more information, see Enabling performance collection schedules for automatic up-
dates on page 75.
You can use the inband or the outband mode for one-time or scheduled configuration data collection.
Inband mode: The inband mode uses RAID Manager Library on the host agent to collect data from
the XP and the P9000 disk arrays. The data is transferred from the XP and the P9000 disk arrays
to the host, and then to the management station.
Outband mode: The outband mode uses the TCP/IP to directly connect to the XP and the P9000
disk array and collect the configuration data through the array SVP.
NOTE:
Using the outband mode ensures that the performance of SAN is not affected because of data
collection.
After the host agents appear under the Host Information tab, the following details from the command
devices are also displayed in the Configuration Collection table, under the Configuration Collection
tab:
