For example: http://[server name]:/pa or http://[server name].[domain name]:/pa. Add administrators and users to P9000 Performance Advisor.
Resolution Ensure that the antivirus software installed on the management station has not blocked the HP StorageWorks P9000 Performance Advisor Security service. Refer to the online help manual provided for the respective antivirus software to identify whether the P9000 Performance Advisor service is blocked and the steps for unblocking the service. Cause The HP StorageWorks P9000 Performance Advisor Tomcat service might not have started after the installation.
Cause The P9000 Performance Advisor login screen does not launch when the short domain name is used. On a few occasions (example, trying to access charts saved in pdf format or reports), P9000 Performance Advisor does not launch when you use localhost in the URL (http:/// pa) to access P9000 Performance Advisor. In such a case, use the IP address or the fully qualified domain name of the management station. Resolution Use the fully qualified domain name ([servername].
Cause Unable to browse to the management station. If you are seeing the Network Error (dns_unresolved_hostname) in your IE browser window, it might be because the URL that you are trying to access is not added as a trusted web site. Resolution To identify the management station to the DNS server: 1. Add to the list of addresses to bypass your proxy server.

4 Frequently Asked Questions P9000 Performance Advisor Licensing Where do I find the P9000 Performance Advisor registration number for generating a permanent license? The P9000 Performance Advisor registration number is included on the product entitlement certificate that is provided with every P9000 Performance Advisor License To USE (LTU) you purchase.
The following warning message is displayed in the Array Performance report that I generated. What does it indicate? WARNING: License violation was detected for this array. This report may not capture performance data about the recent configuration changes made in the XP/P9000 disk array. Please purchase the required Performance Advisor licenses immediately.
I have generated and installed a permanent frame license for a new XP or P9000 disk array. Why does the P9000 Performance Advisor License screen not display the corresponding license details? The corresponding license details are not displayed on the P9000 Performance Advisor License screen, because you have not performed a configuration data collection for the new XP or P9000 disk array (unmonitored XP or P9000 disk array).
When does P9000 Performance Advisor enter the grace period for an XP or P9000 disk array? P9000 Performance Advisor initiates a grace period of 60 days when either of the following conditions is met: • During Instant-on period (first time upgrade or installation of P9000 Performance Advisor v4.5 or later version): • The Instant-on license period of 120 days is over and a permanent license is not yet installed for any of the XP or P9000 disk arrays.
Is the Instant-on license bound to an XP or P9000 disk array? No. The Instant-on license is provided with every instance of P9000 Performance Advisor and is applicable to all the XP or P9000 disk arrays that are monitored by the current instance of P9000 Performance Advisor. What is the indication that a license is installed on P9000 Performance Advisor? After you install the .
f. Click Save to obtain a .doc format of the software license certificate. A new browser window appears and contains the license certificate that was shipped to you earlier. Select File >Save As, from the browser window to save the file. You can also email the certificate (word document) as a file attachment to your email account. I am seeing Capacity Insufficient displayed for an XP disk array on the P9000 Performance Advisor License screen – View License Status section.
the current management station and added to another management station, can I still use that emergency license for the remaining duration? Yes. You can move licenses between management stations. The license validity is fixed at the time of generating the license and is not tied to the movement of licenses between the management stations. NOTE: The above mentioned is valid only if both the management stations are monitoring the same P9000 disk array.
Is there an indication on when the P9000 Performance Advisor database should be archived? Should I wait for the database to grow to X size before it can be archived? Currently, there is no indication for deciding when the database must be archived. However, you can use the following as a rule of thumb to archive data: Auto purge starts when the database size has reached 70% of the allocated disk space and the Auto Grow check box is not selected on the Database – Configure screen.
Does purging or archiving of data also lead to defragmentation of the allocated disk space? It depends on the P9000 Performance Advisor version that is installed on your management station: • In P9000 Performance Advisor versions prior to v3.5, purging of data does not explicitly defragment the allocated disk space. If you want to reduce the database size after purging, you must use the DefragmentDB.bat file and complete the following steps to reduce the database size: 1. 2. 3. 4. 5.
as the data older than the selected start date will be purged for all the XP and P9000 disk arrays connected to the management station. This is because the manual purge process is initiated on a specific date and not for a specific XP or P9000 disk array. • Case2: Manual purge is initiated for an XP or a P9000 disk array for which data collections are in progress.
During the upgrade, can I move or copy the P9000 Performance Advisor database folders to a different location on the same or a different management station? No. HP recommends that the P9000 Performance Advisor database folders remain untouched, as P9000 Performance Advisor uses the files in these folders for the upgrade to complete. The folders not being available can lead to data corruption, permanent data loss, and upgrade failure. Can the database size be reduced using DefragmentDB.bat? No.
1. 2. 3. 4. Stop the P9000 Performance Advisor services (Start -> Programs -> HP Storageworks -> Stop services). Move the data located in %HPSS_HOME%\cache folder to another location on the management station. Move the logs in the pa\tomcat\logs folder to another location on the management station. Start the P9000 Performance Advisor services (Start -> Programs -> HP Storageworks -> Start services).
The auto purge started when the data was being imported. Will I lose the imported data? Auto purge begins if the data storage exceeds 70% of the available disk size. If you are importing data when the auto purge is in progress, the data import activity continues. However, if the imported data is among the oldest data that Performance Advisor has selected for purging, the data that is being imported is purged automatically.
Should I stop the P9000 Performance Advisor services before using the Backup utility? No. You should not stop the P9000 Performance Advisor and Oracle database services while taking backup or restoring data on a management station. The disk space on my management station is full, as the undo.log file seems to have occupied the disk space. Can I stop the P9000 Performance Advisor services, move the undo.log file to another location, and restart the P9000 Performance Advisor services? No.
Can I set the threshold values for LDEVs on the Threshold Settings screen? No. Threshold values cannot be set for LDEVs. Instead, you can set threshold values only for the ports, cache, RAID groups, and DKC resources. The frontend, cache, and backend categories on the Dashboard screen are showing the X icon for the P9000 disk array. Does it indicate that the P9000 disk array is not optimally utilized? Not necessarily.
How are LDEVs displayed in the LDEV Information table on the Dashboard screen? The LDEVs records are displayed in the ascending or descending order based on the LDEV Settings that you will have specified on the Threshold Settings screen. The ascending or descending order is decided based on an LDEV’s average read and write response times. What does the dashboard high watermark indicate? The high water mark is an indication of the maximum average usage value of that resource in the past 24 hours.
From P9000 Performance Advisor v5.0 onwards, default threshold value is also provided for the MP blade Util (%) metric (applicable only for P9000 disk arrays), which is 70%. In addition to providing the threshold values for the other Frontend, Cache, Backend, and MP blade metrics, you can retain the default values or provide values of your choice for the above mentioned metrics.
--------------------------------------------------------------------------------------------------PerformanceAdvisor: ERROR: Can't attach to command device: \\.
I need to monitor response time for a particular RAID group over a shorter duration. Can I collect performance data for less than 60 seconds using P9000 Performance Advisor? No. The minimum duration for collecting performance data using P9000 Performance Advisor is at least one minute. To view data for less than a minute duration, use P9000Watch or the real-time charting feature in P9000 Performance Advisor. Can I view real-time performance graphs for multiple XP and P9000 disk arrays simultaneously? Yes.
When real-time charting is in progress, will it be impacted by either configuration or performance data collections that are happening simultaneously? No. When real time collection is in progress for an XP or a P9000 disk array through a host agent, you can still initiate configuration and performance data collections on the same XP or P9000 disk array through the same host agent, provided you select a different command device.
If your P9000 disk array is already connected to two host agents, you can start separate instances of real-time data collections simultaneously through both the host agents. In this case, P9000 Performance Advisor collects real-time data for a set of five LDEVs through each host agent. I am seeing the following error message when I try to plot a real-time chart for the LDEV, 00:01 on the RealTimeCharting screen.
I have updated the new port number in the realtime.properties file on my management station. However, the communication between the management station and the host agent is not established. How to re-establish the connection? Verify if you have updated the same port number in the realtime.properties file on the associated host agent also. Both the management station and its host agent require the same port number to be provided in the respective realtime.
Can I associate my application with resources that belong to legacy XP disk arrays? No. You cannot associate applications with resources belonging to the following legacy XP disk arrays, XP256, XP48, and XP512, because WWNs of the hosts connected to these XP disk arrays are not available. When can an existing application be associated with an existing host? There may be cases, where the LDEVs associated with an application are made available through two hosts belonging to different WWNs.
A port record appears grayed out in the table under Frontend metrics on the Troubleshooting screen. What does it indicate? The grayed out port record indicates that it is a partner port. A partner ports uses the same CHA MP that is also used by the primary port, which communicates the I/O requests from the application to the associated LDEVs. When you plot a usage graph for the primary port, the usage graph for the partner port is also displayed.
physical LDEV ID. The same procedure should be followed if you want to search for physical LDEVs under Charts. For example, assume that you are searching for the physical LDEV ID, 0:05 that belongs to the XP disk array, 10055. However, the search result shows the same LDEV record highlighted under the XP disk array, 10058. In this scenario, the search result showed the LDEV record, 0:05 highlighted under the XP disk array, 10058, as it may be the first XP disk array under Alarms.
When will “Good Information” alarm be sent? P9000 Performance Advisor dispatches Good Information alarm notifications, which is a Recovery Alarm. Good Information email notification is sent, if the performance collection value goes below the set threshold value. I've provided the new threshold values for an alarm record on the Alarms screen. However, the threshold values are not updated.
How to improve performance of P9000 Performance Advisor when plotting charts for large number of resources? Before plotting charts for large number of resources (for example, more than 100 resources) and for a large data range, clear the following selections in the Chart Work Area: • The Show Data Points check box • The Show Zoom check box Also, split the resources across multiple chart windows.
1. 2. Click the title bars of the chart windows to select the charts (blue border should appear around the chart window). Click Save Chart as PDF. • Print, which allows you to print charts in the Chart Work Area as separate pages. By default, all the active or selected charts can be printed. However, if the charts that you want to print are not selected, do the following to select and print the charts: 1.
The zoom preview panel has sliders that you can use to filter the overall duration in the chart window and view data for a particular focused duration. You can drag the sliders on either side of the time scale to increase or decrease the duration for which you want to view the data points. The existing chart window are accordingly updated to display data points for the duration selected in the Zoom preview panel. The focused area in the Zoom preview panel is highlighted in blue.
The new charts are added always at the end of the Chart Work Area. Every time, I have to scroll down the Chart Work Area to view the new chart when more number of charts are added. Is it possible to view the new chart first? Yes. You can rearrange charts in the Chart Work Area. Click the title bar of the chart window that you want to move and holding down the left mouse button, drag and drop that chart over the first chart in the Chart Work Area.
• Sequential MB Writes The above mentioned metrics are not supported in P9000 Performance Advisor for the continuous access journal pool LDEVs.
When is the displayed for an LDEV on the Troubleshooting screen? P9000 Performance Advisor analyses the previous average read and write response values of an LDEV for the duration you specified. It computes a reference value based on the actual data for the specified duration and verifies whether the average read and write response values of an LDEV are beyond the reference value. If the values are high, it displays a for the corresponding LDEV.
Will P9000 Performance Advisor work if the HP StorageWorks P9000 Performance Advisor Tomcat Monitor service is not running? Yes.

After removing Performance Advisor v3.4.1 on the management station, I did not delete the HPSS folder and started with the v4.5 installation. After the installation completed, I am not able to log into Performance Advisor. Why?

Remove v4.5, delete the HPSS folder manually, and reinstall v4.5 on the management station.
