4. Click Remove Host. The Remove Host button is enabled only when you select a host agent
record.
HP XP7 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 XP7 disk arrays connected to the host agent are also removed. Initiate a
new
configuration collection on the XP and the XP7 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 XP7 Performance Advisor Software
Installation Guide.
Collecting configuration data
You
can collect the configuration data for the XP and the XP7 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 XP7 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 XP7 Performance Advisor collects the updated
configuration
data from the XP and the XP7 disk arrays. If you want HP XP7 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 66)
.
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 XP7 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.
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:
