HP StorageWorks XP Performance Advisor Software v4.6 User and Troubleshooting Guide (T1789-96094, June 2010)

4. Click Remove Host. The Remove Host button is enabled only when you select any host record.
XP Performance Advisor deletes the host record and logs a confirmation on the Event Log screen.
When you remove a host, the data about the command devices that are exposed to the host and the
following data for XP arrays connected to the host are also removed. You should initiate a new
configuration collection on the XP array and also create or configure the above mentioned parameters
again:
• Configuration data
• Performance schedules
• Report schedules
• Alarm configuration data
• Custom groups
If you want to view the host details again, restart the host agent services on that host. A record for
the host is automatically displayed under the Host Information tab. For more information on restarting
host agent services, refer to the HP StorageWorks XP Performance Advisor Software Installation Guide.
Collecting configuration data
You can collect the configuration data for an XP array in the following ways:
• One Time configuration data collection: Use this collection type if you want to collect configuration
data only once. Any new configuration changes to the XP array, like new resources 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 configur-
ation data collection periodically on a hourly, daily, weekly, or monthly basis. Based on the
schedule frequency, XP Performance Advisor collects the updated configuration data from the XP
array. If you want XP Performance Advisor to automatically collect performance data for new re-
sources, you must enable the corresponding performance data collection schedules to automatically
accept and monitor performance of new resources. For more information, see “Enabling perform-
ance collection schedules for automatic updates” on page 56.
You can use the Inband or OutBand mode for one-time or scheduled configuration data collection.
• Inband mode: The Inband mode uses RMLIB on the host agent to collect data from an XP array,
where the data is transferred from the XP array to the host, and then to the management station.
• OutBand mode: The OutBand mode uses Remote Method Invocation (RMI) to collect data from an
XP array through its SVP, where XP Performance Advisor directly communicates with the XP array
to collect its configuration data.
NOTE:
Using the OutBand mode ensures that the performance of Storage Area Network (SAN) is not
affected because of data collection.
After the hosts appear under the Host Information tab, the following details from a command device
are also displayed in the Configuration Collection table, under the Configuration Collection tab:
