4 Frequently Asked Questions HP XP P9000 Performance Advisor Licensing Where do I find the HP XP P9000 Performance Advisor registration number for generating a permanent license? The HP XP P9000 Performance Advisor registration number is included on the product entitlement certificate that is provided with every HP XP P9000 Performance Advisor License To USE (LTU) you purchase.
I have not received the product entitlement certificate and the registration number along with the HP XP P9000 Performance Advisor v4.5 media kit. What should be the process followed to get the product registration number after an upgrade to v4.5 or later version? In order to receive the product entitlement certificate and the registration number, complete the following steps: 1. Enter the required information in the HP XP P9000 Performance Advisor License Entitlement Request text file.
No. Permitted Volumes displayed in the View License Detail section for a specific XP or P9000 disk array are not the same as the Licensed Capacity. Permitted Volumes refers to the capacity of a single license key. The aggregate of the permitted volumes is displayed as the actual license capacity (TB). For example, consider that there is a permanent license and a term license installed on a given XP or P9000 disk array. The permitted volumes (TB) installed are 20 TB and 24 TB respectively.
Yes. The grace period of 60 days is also applicable for term and emergency license types. After a term or an emergency license expires, HP XP P9000 Performance Advisor enters a grace period of 60 days for all the associated XP or P9000 disk arrays. If the current version of HP XP P9000 Performance Advisor is upgraded to v5.0, is the Instant-on license activated after the upgrade is complete? Yes. The Instant-on license is available with HP XP P9000 Performance Advisor v5.0.

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.
What is usable capacity? Is it applicable for XP disk arrays? The usable capacity is applicable only for P9500 disk arrays and calculated as follows: Allocated total LDEVs capacity + unallocated total LDEVs capacity + reserved capacity.
Refer to the answer provided for the FAQ – When the Auto Grow check box is selected, will the database size increase only when it reaches x % of the allocated disk space? Can purged data be recovered? No. Purged data cannot be recovered, as it is permanently deleted and the free disk space released back to the HP XP P9000 Performance Advisor database.
It depends on the kind of purge that is initiated: • If it is a manual purge and the data being collected falls in the date range older than the date that you have selected for purging, you may see discrepancy in the data being displayed on the HP XP P9000 Performance Advisor screens. • If it is a manual purge for an XP or a P9000 disk array, all the data collected till the current collection time is purged.
However, you can first import the v3.5.2 data onto another management station and then upgrade it to v4.0. During the upgrade, can I move or copy the HP XP P9000 Performance Advisor database folders to a different location on the same or a different management station? No. HP recommends that the HP XP P9000 Performance Advisor database folders remain untouched, as HP XP P9000 Performance Advisor uses the files in these folders for the upgrade to complete.
3. 4. Move the logs in the pa\tomcat\logs folder to another location on the management station. Start the HP XP P9000 Performance Advisor services (Start -> Programs -> HP XP P9000 Performance Advisor -> Start services). Is there a procedure to downgrade the HP XP P9000 Performance Advisor database? For example, if HP XP P9000 Performance Advisor was upgraded from v3.5.2 to v4.1, can the database be downgraded to v3.5.2? No.
1. 2. At the command prompt, enter cd ...%PADB_HOME%\tools In the Tools folder, enter DBBackup HP recommends that you provide a date for the defining parameter. For example, if you type DBBackup 07102006, the system provides a backup of all data in a directory named 07102006. To restore the SOLID database: 1. At the command prompt, enter cd ...%PADB_HOME%\tools 2. In the Tools folder, enter DBRestore 3.
The HP XP P9000 Performance Advisor services failed to restart, because the JAVA_HOME variable is not updated and it still points to JRE v1.5 Update 18. So, you need to manually update the JAVA_HOME environment variable to point to the JRE v1.6 folder. Then, try restarting the HP XP P9000 Performance Advisor services. Array dashboard and threshold settings NOTE: P9000 disk arrays are supported only from HP XP P9000 Performance Advisor v5.0 onwards.
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. High watermark is displayed after considering the usage data of a resource in the last 24 hours for a selected metric. NOTE: The dashboard high watermark is available on the Dashboard screen from HP XP P9000 Performance Advisor v4.5 onwards.
performance data collection is initiated at 9:47 AM for a frequency of 5 minutes, the last collection time stamp is updated only after the 5 minutes completes. I have added a command device from SLPR1. Can I collect information through that command device for LUNs presented through other SLPRs? No. If you add a command device from SLPR1, that command device collects information only for the LUNs presented through SLPR1.
HP XP P9000Watch Real-time charting Through real-time charting, you can view real-time metrics collected for RAID groups or LDEVs that belong to an XP or a P9000 disk array. At a time, you can monitor a maximum of five RAID groups or LDEVs in an XP or a P9000 disk array. 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 HP XP P9000 Performance Advisor? No.
The XP10000 and XP20000 type disk arrays are not displayed under Select Components, as the real-time charting is supported only for XP24000 or XP12000 type disk arrays. Why are ports and DKC not available for selection under Select Components on the RealTimeCharting screen for an XP or a P9000 disk array? The ports and DKC are not available for selection, as real-time data collection and charting is only supported for the LDEVs and RAID groups.
Open the realtime.properties file and provide the new port number against the Port.Number field. • On the management station, the realtime.properties file is located in the %HPSS_HOME%/ pa/properties folder. • On the host agent, the realtime.properties file is located in the xppa/realtime/ config folder. NOTE: From HP XP P9000 Performance Advisor v4.6 onwards, the realtime.properties file is renamed as xprmihaserver.properties. I have updated the new port number in the 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.
What metrics should I consider to access the response time of my application? You can look for the performance values of LDEVs, ports, CLPRs, and RAID groups related to the following metrics: LDEV Average read write response time Port IOPS, MBPS, and MP Util% CLPR Cache usage and read hits RAID group RG util%, non seq reads, seq reads, and writes Alarms and alarms history NOTE: The following FAQs are on enhancements or new features introduced in Alarms and Alarms History from v4.5 onwards.
The status of an alarm record changes to Close when the corresponding alarm record is deleted from the Alarms screen. After setting emails to last dispatch level (level 3), will an email be sent, if the threshold value is crossed in the next cycle? HP XP P9000 Performance Advisor sends an email alert, if the cache usage exceeds 10%. To receive further email notification, increase the dispatch level using the Edit option, from the Alarm Config screen. Verify the same in the Event log.
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. You can achieve this by adding new chart windows in the Chart Work Area, and plotting the performance graphs of a subset of resources in the new chart windows.
No. When you save a utilization chart using the Save Chart as PDF option, only the current utilization graph for a resource is saved. The forecasted utilization graph is not saved. Which are the resources for which I can forecast utilization? In addition to forecasting utilization for a ThP pool, you can also forecast utilization for DKA, MP, RAID group, and Cache in HP XP P9000 Performance Advisor starting from v4.6 onwards.
of resources for metrics belonging to the same metric category are automatically added to the new chart window. This continues till you clear the selection for the new chart window.
NA is displayed for the LDEVs that belong to the continuous access journal pools when you want to view the performance values for the following metrics: • MAX Write Resp • AVG Write Resp • Random Write Cache Hits • Random Writes Sequential Write Cache Hits • Sequential Writes • Random MB Writes • Sequential MB Writes The above mentioned metrics are not supported in HP XP P9000 Performance Advisor for the continuous access journal pool LDEVs.
HP XP 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.
The HP XP P9000 Performance Advisor Tomcat Monitor service is only essential for the working of HP XP P9000 Performance Advisor Tomcat service. The HP XP P9000 Performance Advisor Tomcat Monitor service monitors the HP XP P9000 Performance Advisor Tomcat service and restarts the tomcat service if it stops. However, if HP XP P9000 Performance Advisor Tomcat Monitor service stops, it does not impact the functioning of HP XP P9000 Performance Advisor.
