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

4. Click Request Info. The Request Info button is enabled only when you select the host agents. Use
the Shft or the Ctrl key to select multiple host agent records.
The request is executed in the subsequent data collection cycle. Following is the sequence of
events that occur for the selected host agent:
a. P9000 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 P9000 Performance Advisor has retrieved the latest information from the host agent,
the Status changes to Received.
c. The latest time stamp is displayed under Updated.
If there are any configuration changes in the associated XP and the P9000 disk arrays, P9000
Performance Advisor also updates these details on the relevant screens. For example, if the updated
information is about a new command device, an additional record for the new command device is
also displayed under the Configuration Collection tab on the Array View screen.
To collect configuration data from a reconfigured XP or P9000 disk array, perform the above-mentioned
steps (see “Requesting host agent updates” on page 54). During the next data collection cycle, the
host collects the configuration data again from the reconfigured XP or P9000 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 P9000 disk arrays.

Removing host agent information from P9000 Performance Advisor
IMPORTANT:
• You can remove a host agent record when its status shows as Requested or Received under Status.
• If an XP or a P9000 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 P9000 disk array is still available in P9000 Performance
Advisor. This is because, that XP or P9000 disk array is still connected to the other host agent.
• The existing configuration and performance data can be purged for those XP and P9000 disk
arrays that are no longer monitored by P9000 Performance Advisor.
To remove a host agent record:
1. Click 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 P9000 Performance Advisor.
