events that occur for the selected host agent:
a.
HP XP7 Performance Advisor retrieves the updated information from the host agent. This
may take a few minutes depending on the number of LDEVs that are exposed to the host
agent.
The Status displays as Requested and Request Status displays the message, In
progress...please wait.
b.
After HP XP7 Performance Advisor has retrieved the latest information from the host agent,
the Status changes to Received.

Click
Refresh Hosts to manually refresh the Host Information table. If there are any configuration
changes
in the associated XP and the XP7 disk arrays, HP XP7 Performance Advisor also updates

command
device, an additional record for the new command device is also displayed under the
Configuration
Collection tab on the Array View screen.

During the next data
collection
cycle, the host collects the configuration data again from the reconfigured XP or XP7
disk
array and displays under the Configuration Collection tab on the Array View screen. This
process
avoids inconsistencies in the performance data collected for the reconfigured XP or XP7
disk
arrays.

Removing host agent information from HP XP7 Performance Advisor
IMPORTANT:
•
You can remove a host agent record when its status shows as Requested or Received under
Status.
•
If
an XP or an XP7 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 XP7 disk array is still available in HP
XP7
Performance Advisor. This is because, that XP or XP7 disk array is still connected to the
other
host agent.
•
The
existing configuration and performance data can be purged for those XP and XP7 disk
arrays
that are no longer monitored by HP XP7 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 HP XP7 Performance Advisor.
