HP XP P9000 Performance Advisor Software v6.0 User Guide

4. Click Remove Host. The Remove Host button is enabled only when you select a host agent
record.
HP XP 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 XP 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
configuration 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
configuration data collection periodically on a hourly, daily, weekly, or a monthly basis.
Based on the schedule frequency, HP XP P9000 Performance Advisor collects the updated
configuration data from the XP and the P9000 disk arrays. If you want HP XP 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 updates” (page 64).
You can use the outband mode for one-time or scheduled configuration data collection. 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.
• You must wait for at least 30 minutes after changing the Array RWC Login password to perform
the outband mode of configuration collection.
The following table provides a list of the preferred mode of configuration data collection for the
features. Use this as a guideline while performing configuration data collection with the HP XP
P9000 Performance Advisor v6.0.
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:
