4 Frequently Asked Questions HP XP7 Performance Advisor Licensing Where do I find the HP XP7 Performance Advisor registration number for generating a permanent license? The HP XP7 Performance Advisor registration number is included on the product entitlement certificate that is provided with every HP XP7 Performance Advisor License To USE (LTU) you purchase.
In order to receive the product entitlement certificate and the registration number, complete the following steps: 1. Enter the required information in the HP XP7 Performance Advisor License Entitlement Request text file. By default, the HP XP7 Performance Advisor License Entitlement Request text file is located in the %HPSS_HOME%\data\keys folder, if you have upgraded to HP XP7 Performance Advisor v4.5. HP uses the information from this text file to process the registration number request. 2.
For example, consider that there is a permanent license and a term license installed on a given XP or XP7 disk array. The permitted volumes (TB) installed are 20 TB and 24 TB respectively. In this case, the actual license capacity (TB) is calculated as 44 TB.
Is the Instant-on license bound to an XP or XP7 disk array? No. The Instant-on license is provided with every instance of HP XP7 Performance Advisor and is applicable to all the XP or XP7 disk arrays that are monitored by the current instance of HP XP7 Performance Advisor. What is the indication that a license is installed on HP XP7 Performance Advisor? After you install the .
This message implies that you are monitoring an XP disk array for the internal raw disk capacity that has exceeded the actual licensed capacity. This is referred to as Capacity Violation. In this case, HP XP7 Performance Advisor switches to the grace period of 60 days for that particular XP disk array, but continues with the current functions.
HP XP7 Performance Advisor database management What is the maximum permitted size of the database that I must consider while manually increasing the size of the database? The maximum database size that you can select is 320 GB. This is possible when the Auto Grow check box is not selected on the Database – Configure screen. Every time, you select a database number from the Configured Maximum Database Size list on the Database – Configure screen, the allocated disk space increments by the number you select.
Do the purge and database archival options function the same on the HP XP7 Performance Advisor database? No. Manual purge or auto purge processes delete the data completely. Database archival process takes a backup of the data in a .dmp file and then deletes the same data from the HP XP7 Performance Advisor database.
Consider the following scenarios: • Case1: The purge start date is provided as the immediate next day for the manual purge to begin. You may see discrepancy in the data that is displayed on the HP XP7 Performance Advisor screens, as the data older than the selected start date will be purged for all the XP and XP7 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 XP7 disk array.
No. HP recommends that the HP XP7 Performance Advisor database folders remain untouched, as HP XP7 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. DefragmentDB.bat was provided prior to HP XP7 Performance Advisor v3.5 for the purpose of defragmenting the SOLID database space.
No. There is no procedure to downgrade the HP XP7 Performance Advisor after upgrading it to a later version. However, you can consider the following workaround before upgrading the current version of HP XP7 Performance Advisor to a later version: 1. Use the Backup utility to take a backup of the current version of HP XP7 Performance Advisor database, which is v3.5.2 in this scenario. 2. Upgrade to HP XP7 Performance Advisor v4.1. If the upgrade does not complete, you can roll back to v3.5.
1. 2. 3. At the command prompt, enter cd ...%PADB_HOME%\tools In the Tools folder, enter DBRestore Enter the same parameter that you entered in the command prompt for the database backup. For example, if you entered DBBackup 07102006 to back up your data, you must enter DBRestore 07102006 to restore the data from the backup contained in the 07102006 directory. To reset the SOLID database: 1. At the command prompt, enter cd ...%PADB_HOME%\tools 2.
Why does ? appear for an XP or an XP7 disk array in the XP/XP7 Array Health section on the Dashboard screen, though the threshold values are set? The ? icon appears in the XP/XP7 Array Health section if performance data collection is not happening for an XP or XP7 disk array. 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 dashboard high watermark is disabled, if you select multiple resources and plot their performance graphs for different metrics. The dashboard high watermark is displayed only when you select a single resource and metric combination. Why is the dashboard high watermark not displayed for LDEVs? The dashboard high watermark is not displayed for LDEVs, because there is no option to set the threshold values for LDEVs on the Threshold Settings screen.
The last collection time stamp get updated based on the performance data collection frequency set for each individual resource. Since the frequency set for DKC is 5 minutes, it appears first. The last collection time stamp for port data collection gets updated only after 10 minutes duration.
Yes. You can collect real-time performance data and view real-time graphs for multiple XP and XP7 disk arrays. However, ensure that the real-time data collections are happening through dedicated host agents. For example, if host agent_A and host agent_B are connected to both XP disk array_1 and XP disk array_2, initiate a real-time data collection on XP disk array_1 through host agent_A and on XP disk array_2 through host agent_B.
At a time, you can select only five LDEVs or RAID groups in an XP or an XP7 disk array to view their real-time performance graphs.
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.
What are the different levels at which I can view performance data of resources associated with my application? You can view the performance data of LDEVs, ports, CLPRs, and RAID groups at the following three levels: • Application level: Displays performance data of all the LDEVs, ports, CLPRs, and RAID groups that are associated with your application • Host level: Displays performance data of all the LDEVs, ports, CLPRs, and RAID groups that are associated with your application through the specific host
Alarms and alarms history NOTE: The following FAQs are on enhancements or new features introduced in Alarms and Alarms History from v4.5 onwards. Therefore, these FAQs are not applicable to HP XP7 Performance Advisor versions prior to v4.5. How does search functionality work if I have to search for a physical LDEV under Alarms? By default, the search function highlights the first occurrence of the physical LDEV record under Alarms.
HP XP7 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.

What is the recommendation if I have to forecast DKA, MP, RAID group, or Cache utilization for a week? To forecast utilization for a week, HP recommends that there be a minimum of 250 data points or the performance data has been collected for two or more days. Can I preview data in the zoom preview panel for any duration? No. You can preview the data in the zoom preview panel only for the duration selected in the respective chart window.
The virtual volumes like ThP or snapshot pools are displayed only if those resources can be configured on your XP or an XP7 disk array. Therefore, verify if your XP or an XP7 disk array supports virtual volumes to be configured. Does the Legends check box selection in the individual chart windows override the Show Legends check box selection in the Chart Work Area? Yes. If the Legends check box is selected in the individual chart window, it supersedes the Show Legends selection in the Chart Work Area.
The above mentioned metrics are not supported in HP XP7 Performance Advisor for the continuous access journal pool LDEVs.
HP XP7 Performance Advisor also displays the duration when the variations were observed. The durations and the corresponding dates when the load was high on the LDEVs are displayed in the table that first appears when you click the . I want to view the chart. How to close the table and view the chart? Clear the Show Peak Load check box in the Chart Work Area. Array View The Array View MP Blade screen does not show the MP blade summary.
4. Click Remove Host. HP XP7 Performance Advisor deletes the host agent record and logs a confirmation on the Event Log screen. When you remove a host agent, the data about the command devices that are exposed to its host and the following data for the XP and XP7 disk arrays are also removed.
